The threat of chemical, biological, radiologic, nuclear, and explosive (CBRNe) terrorist attacks has increased over time. The need for rapid and effective responses to such attacks is paramount. Effective medical counter-measures to CBRNe events are critical and training for such may effectively occur early in physician training. While some medical specialties are more involved than others, counter-terrorism medicine (CTM) spans all medical specialties.

All United States allopathic medical schools were examined via online curriculums and queries for academic content related to CBRNe and terrorist medical counter-measures.

Analysis of 153 United States allopathic medical schools demonstrated that 15 (9.8%) medical schools offered educational content related to CBRNe and terrorist counter-measures. This is in contrast to legislation following the September 11, 2001 attacks that called for high priority for such education.

Effective CBRNe medical counter-measures are currently in place; however, there is room for improvement in education that may begin during medical school. While certain medical specialties such as emergency medicine, primary care, and dermatology may have specific niches in such events, physicians of all medical specialties have something to offer, and even a basic education in medical school can help best prepare the nation for future attacks.

Health care provision depends on reliable critical infrastructure (CI) to power equipment and to provide water for medication and sanitation. Attacks on CI limiting such functions can have a profound and prolonged influence on delivery of care.

A retrospective analysis of the Global Terrorism Database (GTD) was performed of all attacks occurring from 1970-2020. Data were filtered using the internal database search function for all events where the primary target was “Utilities,” “Food or Water Supply,” and “Telecommunications.” For the purposes of this study, the subtype “Food Supply” was excluded. Events were collated based on year, country, region, and numbers killed and wounded.

The GTD listed 7,813 attacks on CI, with 6,280 of those attacks targeting utilities, leading to 1,917 persons directly killed and 1,377 persons wounded. In total, there were 1,265 attacks targeting telecommunications causing 205 direct deaths and 510 wounded. Lastly, 268 attacks targeted the water supply with 318 directly killed and 261 wounded. Regionally, South America had the most attacks with 2,236, followed by Central America and the Caribbean with 1,390. Based on infrastructure type, the most attacks on utilities occurred in El Salvador (1,061), and the most attacks on telecommunications were in India (140). Peru (46) had the most attacks on its water supply.

The regions with the highest number of total attacks targeting CI have historically been in South America, with more attacks against power and utilities than other infrastructure. Although the numbers of persons directly killed and wounded in these attacks were lower than with other target types, the true impacts on lack of health care delivery are not accounted for in these numbers. By understanding the pattern and scope of these attacks, Counter-Terrorism Medicine (CTM) initiatives can be created to target-harden health care-related infrastructure.

Russia’s annexation of Crimea in 2014, and the recent Russo-Ukrainian war that started in 2022, were triggers that radically changed the perception of security in the Nordic and Baltic countries. The on-going Russian hybrid war has resulted in a renewed global interest in the safety and security of many countries (eg, the Nordic-Baltic Eight). The prospective North Atlantic Treaty Organization (NATO) membership of Finland and Sweden may drastically change the regional military and political landscape.

The objective of this study was to identify and characterize all documented terrorist attacks in this region as reported to the Global Terrorism Database (GTD) from 1970 through 2020.

The GTD was searched using the internal database functions for all terrorism incidents in the Nordic-Baltic states: Denmark, Estonia, Finland, Iceland, Latvia, Lithuania, Norway, and Sweden.

Temporal factors, location, target type, attack and weapon type, perpetrator type, number of casualties, and property value loss were collated. Results were exported into an Excel spreadsheet for analysis.

There were 298 terrorism-related incidents from 1970 through 2020. Most attacks occurred in Sweden, followed by Norway and Finland. No entries were recorded for the Baltic states prior to their independency in 1991. The 298 incidents resulted in a total of 113 fatalities and 277 injuries.

Facility/infrastructure attacks were the most frequently identified attack type (35.0%), followed by bombings and explosions (30.9%). Armed assaults were responsible for 80 fatalities and 105 injuries, followed by bombings/explosions with 15 fatalities and 72 injuries. The predominant target types were immigrants and refugee shelters (64/298 incidents). In only 33.6% of the incidents, perpetrators were known. Right-wing assailants represented the largest group, accounting for 27 incidents.

From 1970 through 2020, there were 298 terrorist attacks in the Nordic-Baltic Eight. Sweden accounted for 50% of incidents.

The profile of terrorist attacks was very diverse, as were the perpetrators and targets. Every country had its own incident characteristics. The surge of right-wing extremism must be closely monitored.

The use of chemical, biological, radiation, and nuclear (CBRN) weapons is not new, and though rare, it is an issue of concern around the world due to their ability to cause large-scale mass-casualty events and their potential threat to global stability. The purpose of this study is to explore the use of CBRN weapons by non-state actors through analysis of the Violent Non-State Actor (VNSA) CBRN Event database, and aims to better inform health care systems of the potential risks and consequences of such events.

Data collection was performed using a retrospective database search through the VNSA CBRN Event database.

A total of 565 events were recorded. Five hundred and five (505) events (89.4%) involved single agents while 60 events (10.6%) involved multiple agents. Fatalities numbered 965 for chemical agents, 19 for biological agents, and none for radiological and nuclear events. Injuries numbered 7,540 for chemical agents, 59 for biological agents, 50 for radiological events, and none for nuclear attacks. Fatality and injury per attack was 2.22 and 17.37, respectively, for chemical event agents and 0.15 and 0.48, respectively, for biological event agents.

Violent Non-State Actors were responsible for 565 unique events around the world involving the use of CBRN weapons from 1990-2020. The United States (118), Russia (49), and Iraq (43) accounted for the top three countries where these events occurred. While CBRN events remain relatively rare, technological advances have the potential to facilitate the use of such weapons as part of a hybrid warfare strategy with significant repercussions for civilian health and health care systems.

Terrorist attacks against hospitals and health care providers have disproportionally increased during the last decades. A significant proportion of these attacks targeted abortion clinics and abortion providers. In the light of the overturning of Roe v. Wade in 2022, an increase of anti-abortion terrorist attacks is anticipated. Therefore, it becomes imperative to gain further insight into the risk and characteristics of past terrorist attacks. This study aimed to review terrorist attacks against health care targets providing abortion services from 1970 through 2020.

Data collection was performed using a retrospective database search through the Global Terrorism Database (GTD). The GTD was searched using the internal database functions for all terrorist attacks against abortion health care providers from January 1, 1970 - December 31, 2020. Temporal factors, location, attack and weapon type, and number of casualties or hostages were analyzed using descriptive statistics.

In total, 262 terrorist attacks were identified in five different countries. The majority (96.6%) occurred in the United States, with the highest counts during the last 20 years of the 20th century. Facility and infrastructure attacks were the most common attack types, followed by bombings and explosions. The attacks resulted in 34 injuries and nine fatalities. Kidnapping took place in three incidents. Of all successful attacks, 96.9% resulted in property damage.

Abortion-related health care facilities and providers have repeatedly been the target of terrorists over the past decades. Nearly all of these attacks took place in the United States, with the highest counts during the last 20 years of the 20th century.

In recent decades, an increasing number of terrorist attacks have been carried out against medical institutions, hospitals, and health care workers. These attacks, that often result in high numbers of casualties and impaired access to health services, have a more significant impact on people’s sense of security than attacks against military and police targets. Attacks on ambulances – especially on the African continent – have been sparsely studied. This study examines attacks on ambulances on the African continent during the period from 1992-2022 (until December 31, 2021).

Reports of ambulance terrorism were extracted from the Global Terrorism Database (GTD), RAND Database of Worldwide Terrorism Incidents (RDWTI), United Nation’s Safeguarding Health in Conflict Coalition (SHCC) database, Armed Conflict Location and Event Data Project (ACLED), Surveillance System for Attacks on Health Care (SSA) database, and Aid Worker Security Database (AWSD). Furthermore, a grey literature search was performed. The date and location of the attacks, perpetrators, weapon and attack types, and the number of victims (dead and wounded) and hostages were collected. Results were exported into an Excel spreadsheet (Microsoft Corp.; Redmond, Washington USA) for analysis.

During the 30-year study period, 166 attacks were observed in 18 African countries. The number of attacks significantly increased since 2016, with 81.3% of the attacks taking place from 2016 to 2022. In total, 193 people died and another 208 were injured. Attacks with firearms were most frequently noted (92 cases; 55.4%), followed by attacks with explosive devices (26 cases; 15.7%). A significant number of ambulances were hijacked (26 cases; 15.7%) and subsequently used for other terrorist attacks. In seven attacks, ambulances were used as vehicle-born improvised explosive devices (VBIEDs).

In this database study on ambulance terrorism in Africa, it was found that the reported occurrence of attacks increased from 2013 onwards, including the rise of ambulances used as VBIEDs. These findings suggest that ambulance terrorism represents a real, significant risk that both governments and health care institutions must address.

Sub-Saharan Africa (SSA) has become a hotspot for global terrorism, with nearly 50% of global terror-related deaths occurring in SSA in 2021. With a large population and complex geopolitical and social climate, terrorist activity further burdens an already strained medical system. This study provides a retrospective descriptive analysis of terrorist-related activity in SSA from 1970-2020.

A retrospective analysis of the Global Terrorism Database (GTD) was performed for the region of SSA from 1970-2020. Data were filtered using the internal database search function for all events in the following countries: Angola, Benin, Botswana, Burkina Faso, Burundi, Cameroon, Central African Republic, Chad, Comoros, the Democratic Republic of the Congo, Djibouti, Equatorial Guinea, Eritrea, Ethiopia, Gabon, Gambia, Ghana, Guinea, Guinea-Bissau, Ivory Coast, Kenya, Lesotho, Liberia, Madagascar, Malawi, Mali, Mauritania, Mozambique, Namibia, Niger, Nigeria, People’s Republic of the Congo, Republic of the Congo, Rhodesia, Rwanda, Senegal, Seychelles, Sierra Leone, Somalia, South Africa, South Sudan, Sudan, Swaziland, Tanzania, Togo, Uganda, Zaire, Zambia, and Zimbabwe. Number of attacks, deaths, and injuries, as well as primary weapons types, country where attacks occurred, and primary target types, were collated and analyzed.

A total 19,320 attacks were recorded, resulting in 77,565 deaths and 52,986 injuries. Firearms were the most frequent weapons used (8,745), followed by explosives (6,031), unknown (2,615), and incendiary (1,246), with all others making up the remainder (683.) Private citizens and property were the most frequently targeted entities (8,031), followed by general government facilities (2,582), police (1,854), business (1,446), military (805), diplomatic government facilities (741), and religious figures/institution (678), with all other targets making up the remainder (3,183).

The majority of deaths from terrorism in SSA are the result of firearm attacks and explosions. Nigeria, Somalia, South Africa, The Democratic Republic of the Congo, and Sudan have had the largest number of attacks since 1970, and Nigeria has the largest number of people killed and injured. The health implications of terrorist attacks are often compounded by violence and pose unique challenges to governments, populations, and aid organizations. By understanding the impact and scope of terrorist activity in SSA, Counter-Terrorism Medicine (CTM) initiatives can be employed to improve health care outcomes.

This study aims to analyze and describe terrorism-related attacks in East Asia from 1970 through 2020.

East Asia consists of South Korea, North Korea, Singapore, Hong Kong, China, Japan, Taiwan, and Macao. According to the Global Terrorism Index (GTI) 2022, the impact of terrorism in East Asia is very low. However, the assassination of former Japanese Prime Minister Shinzo Abe on July 8, 2022 demonstrates that East Asia is not safe from terrorist attacks. This descriptive analysis of terrorist attacks in East Asia will help first responders, Emergency Medical Services (EMS), hospital-based medical providers, and policymakers establish a more refined hazard vulnerability assessment (HVA) framework and develop a Counter-Terrorism Medicine (CTM) mitigation, preparedness, response, and recovery plan.

This is a descriptive observational study drawing data from the Global Terrorism Database (GTD) from January 1, 1970 through December 31, 2020. Epidemiology outcomes included primary weapon type, primary target type, the country where the incident occurred, and the number of total deaths and injured collected. Data from 2021 were not yet available at the time of this study. Results were exported into an Excel spreadsheet (Microsoft Corp.; Redmond, Washington USA) for analysis.

There were 779 terrorism-related events in East Asia from 1970 through 2020. In total, the attacks resulted in 1,123 deaths and 9,061 persons injured. The greatest number of attacks (371; 47.63%) occurred in Japan and the second most occurred in China (268; 34.4%). Explosives were the most used primary weapon type (308; 39.54%) in the region, followed by incendiary devices (260; 33.38%). Terrorist attacks drastically diminished from their peak of 92 in 1990, but there were additional peaks of 88 in 1996, 18 in 2000, 20 in 2008, and 36 attacks in 2014.

A total of 779 terrorist attacks occurred from 1970 through 2020 in East Asia, resulting in 1,123 deaths and 9,061 injuries. Of those, 82.03% attacks occurred in Japan and China. Terrorist attacks drastically diminished since their peak in 1996, but there is an overall uptrend in attacks since 1999.

The on-going Russo-Ukrainian war has resulted in a renewed global interest in the safety and security of nuclear installations and the possibility of nuclear disasters caused by warfare and terrorism.

The objective of this study was to identify and characterize all documented terrorist attacks against nuclear transport, nuclear facilities, and nuclear scientists as reported to the Global Terrorism Database (GTD) over a 50-year period.

The GTD was searched for all terrorist attacks against nuclear facilities, nuclear scientists, nuclear transport, and other nuclear industry-related targets in the period from 1970-2020. Analyses were performed on temporal factors, location, target type, attack and weapon type, perpetrator type, number of casualties, and property value loss.

Ninety-one incidents that occurred from 1970 through 2020 were included. Incidents took place in 25 countries and nine world regions, with most (42; 46.1%) occurring in Western Europe.

During these 50 years, 91 incidents resulted in 19 fatalities and 117 injuries. One perpetrator was killed during an incident and one other assailant was injured.

Bombings and explosions were the most frequently identified attack type (n = 40; 44.0%), followed by facility/infrastructure damage (n = 24; 26.4%) and armed assaults and assassinations (both n = 7; 7.7%).

Nuclear power plants and reactors under construction were targeted in 13 (14.3%) and eight (8.8%) incidents, respectively. Most of the attacks took place on other nuclear industry-related sites.

Terrorist attacks carried out by non-state perpetrators against nuclear facilities, nuclear scientists, nuclear transport, and other nuclear industry-related targets are rare, with only 91 incidents in a 50-year period. None of the attacks resulted in radioactive fallout or environmental contamination. Most of the attacks took place outside a nuclear power plant.

The coronavirus disease 2019 (COVID-19) pandemic enabled a situational type of terrorism with mixed racist, anti-government, anti-science, anti-5G, and conspiracy theorist backgrounds and motives.

The objective of this study was to identify and characterize all documented COVID-19-related terrorist attacks reported to the Global Terrorism Database (GTD) in 2020.

The GTD was searched for all COVID-19-related terrorist attacks (aimed at patients, health care workers, and at all actors involved in pandemic containment response) that occurred world-wide in 2020. Analyses were performed on temporal factors, location, target type, attack and weapon type, attacker type, and number of casualties or hostages. Ambiguous incidents were excluded if there was doubt about whether they were exclusively acts of terrorism.

In total, 165 terrorist attacks were identified. With 50% of incidents, Western Europe was the most heavily hit region of the world. Nonetheless, most victims were listed in Southeast Asia (19 fatalities and seven injured). The most frequent but least lethal attack type concerned arson attacks against 5G telephone masts (105 incidents [60.9%] with only one injured). Armed assaults accounted for most fatalities, followed by assassinations. Incendiary and firearms were the most devastating weapon types.

This analysis of the GTD, which identified 165 COVID-19-related terrorist attacks in 2020, demonstrates that the COVID-19 pandemic truly resulted in new threats for COVID-19 patients, aid workers, hospitals, and testing and quarantine centers. It is anticipated that vaccination centers have become a new target of COVID-19-related terrorism in 2021 and 2022.

Mass gatherings are vulnerable to terrorist attacks and are considered soft targets with potential to inflict high numbers of casualties. The objective of this study was to identify and characterize all documented terrorist attacks targeted at concerts and festivals reported to the Global Terrorism Database (GTD) over a 50-year period.

The GTD was searched for all terrorist attacks against concerts and festivals that occurred world-wide from 1970 through 2019. Analyses were performed on temporal factors, location, target type, attack and weapon type, attacker type, and number of casualties or hostages. Ambiguous incidents were excluded if there was doubt about whether they were exclusively acts of terrorism. Chi-square tests were performed to evaluate trends over time and differences in attack types.

In total, 146 terrorist attacks were identified. In addition to musical concerts, festivals included religious, cultural, community, and food festivals. With 53 incidents, South Asia was the most heavily hit region of the world, followed by the Middle East & North Africa with 25 attacks. Bombings and explosions were the most common attack types. The attacks targeted attendees, pilgrims, politicians, or police/military members who secured the concerts and festivals.

This analysis of the GTD, which identified terrorist attacks aimed at concerts and festivals over a 50-year period, demonstrates that the threat is significant, and not only in world regions where terrorism is more prevalent or local conflicts are going on. The findings of this study may help to create or enhance contingency plans.

Terrorism remains a major threat and concern in many countries around the world. Pediatric populations represent approximately 30% of the world population, and in the event of a terrorist attack, can either be primary targets, to include the possibility of abduction, or unintended victims. They are unique in their vulnerabilities and, therefore, require special consideration.

This study is a semi-quantitative, epidemiological analysis of all terrorism-related pediatric fatalities and injuries sustained from 1970-2019. Data collection was performed using a retrospective database search through the Global Terrorism Database (GTD). Summaries of events including search terms associated with pediatric population were individually reviewed and those describing the deaths, injuries, or abductions were tallied.

Of the over 200,000 terror events, 2,302 events met inclusion criteria. This represented 1.14% of total events which involved death, injury, or abduction. Of 2,032 events, a total of 2,275 pediatric fatal injuries (FI) were recorded, as well as 2,280 pediatric non-fatal injuries (NFI). The most common weapons used in all attacks involving the pediatric population were explosives (1,539 [66.8%]), firearms (543 [23.5%]), other (169 [7.3%]), and melee (83 [3.6%]). A total of 275 of the 2,032 events were related to abductions, with 71 cases involving the abduction of 10 individuals or more.

Pediatric casualties in terrorist events represent a small proportion of overall victims. However, it should be understood that the pediatric population has unique vulnerabilities, and when directly impacted by terrorism, can have long-term physical and psychosocial sequelae, as well as a devastating emotional impact on the community.

Violence against primary care providers (PCPs) has increased during the current pandemic. While some of these violent acts are not defined as terrorist events, they are intentional events with an aim to disrupt, kill, or injure. Despite their pivotal role in health care, little is known about the risk for PCPs as targets of terrorism.

Data collection was performed using a retrospective database search through the Global Terrorism Database (GTD). The GTD was searched using the internal database search functions for all terrorist attacks against PCPs and their offices from January 1, 1970 - December 31, 2019. Years 2020 and 2021 were not yet available at the time of the study. Primary attack and weapon type, location (country, world region), and number of deaths and injuries were collated. Results were exported into an Excel spreadsheet (Microsoft Corp.; Redmond, Washington USA) for analysis.

There were 29 terrorist attacks against PCPs and their offices from 1970-2019. The majority of attacks occurred during or after 2010. There were 58 fatalities, 52 injured, and 13 hostages. Most documented attacks took place in Pakistan, the United States, and Sri Lanka. Bombings concerned 55% of cases and 21% were hostage-takings.

Although less common than attacks on other health care related targets, terrorist attacks against PCPs have occurred. The majority of attacks occurred during the last decade. Future studies are warranted to further assess the risk of terrorist attacks against PCPs: before, during, and beyond the current pandemic.

Over the past five decades, Eastern Europe has seen relatively little in terms of terrorist attacks. The recent escalation of the Russo-Ukrainian conflict has, however, placed a new spotlight on the region, and new questions and concerns around war, conflict, insurgency, and terrorism are being posed. The Russian invasion and extensive combat operations, the largest in Europe since World War II, are occurring across Ukraine where there are 15 active nuclear reactors, not including the Chernobyl site, that are vulnerable to attack or sabotage. In addition, Eastern Europe has been heavily affected by COVID-19, exposing broad vulnerabilities in an otherwise fragile health care system. This raises concerns over the ability of Eastern European health care institutions to absorb surge and manage terrorist attacks or acts of violent extremism. This study provides an epidemiological description of all terrorism-related fatalities and injuries in Eastern Europe sustained from 1970 – 2019.

Data collection was performed using a retrospective database search through the Global Terrorism Database (GTD). The GTD was searched using the internal database functions for all terrorism events which occurred in Eastern Europe from January 1, 1970 - December 31, 2019. Years 2020 and 2021 were not yet available at the time of this study. Primary weapon type, country where the incident occurred, and number of deaths and injured were collated. Results were exported into an Excel spreadsheet (Microsoft Corp.; Redmond, Washington USA) for analysis.

There were 3,901 terrorism-related events in Eastern Europe between the years 1970 and 2019, inclusive. In total, the attacks resulted in 5,391 deaths and 9,538 persons injured. Explosives were the most commonly used weapon type in 59.2% of all attacks in the region, followed by firearms in 27.6%.

From 1970 through 2019, a total of 3,901 terrorist attacks occurred in Eastern Europe, inflicting 5,391 deaths and 9,538 injuries. Of those, 72.3% occurred in Russia and Ukraine. Terrorist attacks sharply declined since the peak in 2014, but there is an overall uptrend in attacks since the 1970s.

The recent United States (US) troop withdrawal out of Afghanistan under a February 2020 US-Taliban agreement and the rapid concurrent collapse of the Afghan military, followed by the ascendance of the Taliban, has placed an international spotlight around the future of South Asian countries. Security threats, in particular, will likely escalate within the region and beyond, with significant concerns around the resurgence of terrorism and violence in the region. This study aims to provide an epidemiological description of all terrorism-related attacks in South Asia sustained from 1970 – 2019. These data will be useful in the development of education programs in Counter-Terrorism Medicine and provide an insight into potential attacks in the future.

Data collection was performed using a retrospective database search through the Global Terrorism Database (GTD). The GTD was searched using the internal database search functions for all events which occurred in Afghanistan, Bangladesh, Bhutan, India, Maldives, Mauritius, Nepal, Pakistan, and Sri Lanka (collectively referred to as South Asia) from January 1, 1970 - December 31, 2019. Primary weapon type, primary target type, country where the incident occurred, and number of deaths and injuries were collated and exported for analysis.

In total, 23.69% of all terrorist attacks from 1970-2019 occurred in the South Asia region, causing 96,092 deaths and 141,333 non-fatal injuries. Of those, 50.1% of attacks in South Asia used explosives, 31.9% used firearms, 9.4% used unknown weapons, 5.9% used incendiary attacks, 2.3% were melee attacks, and <0.5% used chemical, biological, and other weapon types.

Over 88% of the attacks occurred in Afghanistan, Pakistan, and India combined. While there has been a decline in attacks since a peak in 2014, there are concerns of a significant increase in terrorism activity in recent months which could impact an already fragmented health care system. The use of explosives and firearms as attack modalities accounted for 82.0 % of all weapon types used, but the impact of terrorism and conflict expands beyond simple death and casualty tolls.

The use of chemical weapons in terrorist attacks, though rare, remains a significant challenge and concern due to their ability to inflict mass casualties. Chemical attacks remain a topic of interest for Disaster Medicine (DM) and Counter-Terrorism Medicine (CTM) specialists and are clearly an area in need of enhanced preparedness. This study aims to provide an epidemiological description of all terrorism-related attacks using chemical agents as a primary weapon, sustained from 1970 - 2019. These data will be useful in the development of education programs in CTM and provide an insight into how best to prepare for potential attacks in the future.

Data collection was performed using a retrospective database search through the Global Terrorism Database (GTD). The GTD was searched using the internal database search functions for all events using chemical weapons as a primary attack method from January 1, 1970 - December 31, 2019. Years 2020 and 2021 were not yet available at the time of the study. The GTD also details the specific chemical used, when known, in the summary of incidents. Results were exported into an Excel spreadsheet (Microsoft Corp.; Redmond, Washington USA) for analysis.

A total of 292 terrorist attacks involving chemical agents as a primary attack method were recorded from 1970 - 2019, registering 284 deaths and 13,267 injuries. Acid (52) was the most commonly used chemical agent, followed by “unspecified poison” (43), “unknown chemical agents” (29), “unspecified gas” (27), tear gas (27), chlorine gas (24), cyanide (21), mercury (9), pepper spray or mace (9), mustard gas (8), insecticide or 1080 (8), diphenylamine chloroarsine (7), phosphate or phosphorous (3), sodium hydroxide or corrosive liquid (3), sarin (2), “unspecified drugs” (2), VX nerve gas and other nerve gas (2), pesticides (2), cleaning chemicals/paint thinner (2), ammonia (2), anesthesia agent (1), arsenic (1), chlorine and mustard gas mix (1), phenarsazine chloride (1), rat poison (1), unknown irritative gas (1), hydrochloric acid and sodium cyanide mix (1), unknown white powder (1), antiseptic dye (1), and chlorine gas and white phosphorous mix (1).

The use of chemical weapons in warfare, though prohibited by the Chemical Weapons Convention (CWC), remains a rare but concerning terrorist attack methodology. In recent years, there have been more instances where potentially deadly chemicals have been used in civilian settings. Dual use industrial chemicals, in particular, pose a significant concern. Acid was the most commonly used chemical weapon in 52 attacks. Tear gas, chlorine, and cyanide were each used in over 20 attacks. Both DM and CTM specialists advocate for better preparedness and response training for intentional events in civilian settings.

Educational institutions around the world have long been targets of terrorist attacks. Schools, colleges, and universities often lack security measures against intentional threats and may be viewed as relatively easy, soft targets with high potential for mass casualties. The long-term psychosocial impact on children, youth, and survivors of terrorist attacks are significant and recovery remains a challenge. Deliberate attacks on students and children, in particular, can also often gain mass-media attention, provoke significant community unrest, and place a spotlight on the local government’s inability to protect the vulnerable. This study is an epidemiological examination of all terrorism-related events targeting educational institutions from 1970-2019.

Data collection was performed using a retrospective search through the Global Terrorism Database (GTD). The database was searched using the internal search functions for all events that occurred from January 1, 1970 - December 31, 2019. “Educational institutions” as a primary target type was selected for the purpose of this study and events were further sub-classified by country and attack type. All classifications were pre-determined by the GTD.

The GTD listed 4,520 attacks against educational institutions, recording 3,732 deaths and 9,920 wounded. This accounted for 2.7% of all terrorist attacks (total 168,003 attacks against all target types). There has been a downtrend in attacks since the 2014 peak when 344 attacks were recorded that year. Pakistan recorded the most attacks with 969 events, followed by Afghanistan (369), India (311), and Iraq (279). The most common attack types included bombing/explosions (2290), facility/infrastructure attacks (636), armed assaults (628), hostage takings (kidnappings [415]), assassinations (357), unarmed assaults (72), unknown (67), hostage takings (barricade incidents [46]), and hijackings (9).

Eight hundred seventy-three of the 4,520 attacks were recorded against teachers, professors, and instructors and 486 attacks were recorded against “other personnel” such as security and non-teaching staff.

Terrorist attacks on educational institutions are rare but significant target types. In total, 41.2% of attacks on educational institutions occurred in South Asia, followed by 18.9% in the Middle East and North Africa. Western Europe and North America accounted for 3.9% and 3.6%, respectively. Educational institutions around the world should evaluate their risks and put in place appropriate hardening measures as well as preparedness and recovery plans to intentional threats.

Hospitals are vulnerable to terrorist attacks, as they must remain easily accessible to the general public. Hospitals are also occupied with both staff and patients 24 hours a day, 365 days a year, meaning that any attack is almost guaranteed to inflict a multitude of casualties. In addition to the immediate effects of attacking a hospital, there are also uniquely devastating second- and third-order effects when hospitals are attacked.

A focused search of the Global Terrorism Database (GTD) was performed to identify terrorist attacks against hospitals throughout the world. Data between the years 1970-2018 were selected, which included 191,465 entries in total. These entries were then searched for incidents containing the term “hospital” and the results were manually searched to identify trends in the number of incidents occurring per year, as well as the armament that was employed, and the regions of the world where the attacks occurred.

A total of 430 terrorist attacks on hospitals were identified in the GTD, resulting in 1,291 deaths and an additional 1,921 wounded. The frequency of terrorist attacks against hospitals has been steadily increasing over the last two decades and is disproportionate to the overall increase in terrorist attacks against all target types. Attacks have been carried out against hospitals in 61 different countries. The most common method used in these attacks was “bombing/explosion,” which accounted for 299 attacks. Of the known terrorist groups identified in the GTD, “Houthi extremists (Anshar Allah)” and “Islamic State of Iraq and the Levant (ISIL)” carried out the greatest number of attacks on hospitals.

There has been a disproportionate rise in the frequency of terrorist attacks on hospitals when compared to other target types, highlighting the vulnerability of these key structures. Unsurprisingly, these attacks have inflicted large casualty counts in addition to disrupting community health care and disaster response. Attacks against hospitals have been reported on every inhabited continent except Australia, making their protection a matter of international security. The rate of terrorist attacks on hospitals has increased dramatically over the last two decades, creating an urgent need to develop improved defense strategies that will better ensure their protection.
