Sports venues foster community and support local economies. Due to their capacity to host hundreds to thousands of spectators, sports venues are vulnerable to becoming targets of terrorism. Types of venues targeted, regional trends, and methods of attack employed world-wide have not been well-described.

A search of the Global Terrorism Database (GTD) was conducted from 1970 through the end of 2019. Pre-coded variables for target type “business” and target subtype “entertainment/cultural/stadium/casino” were used to identify attacks involving venues where sports events might be viewed by spectators as part of an audience. Sports venues were specifically identified using the search terms “sport,” “stadium,” ”arena,” and “ring,” as well as mention of any specific sport. Two authors then manually reviewed each entry for specific information to confirm appropriateness for inclusion, selecting preferentially for attacks against venues where watching a sports event was the primary focus for the majority of the attendees. Descriptive statistics were performed using R (3.6.1).

Seventy-four (74) terrorist attacks targeting sports venues were identified from January 1, 1970 through December 31, 2019. Thirty-three (33) attacks, or 44.6% of attacks, involved soccer stadiums or soccer venues, while 33.8% of attacks (25 attacks) involved unspecified sports venues. A bombing or explosion was the most frequent method of attack employed, comprising 87.8% of attacks. The highest number of attacks occurred in the Middle East & North Africa. In total, 213 persons died and 699 more were wounded in attacks against sports venues.

Although terrorist attacks against sports venues are uncommon, they carry the risk of mass casualties, especially when explosives are used. A greater understanding of the threat posed by terrorist attacks against sports venues can aid emergency preparedness planning and future medical responses.

The purpose of this study was to critically review the provision of medical care at mass gatherings as described in 25 years of case reports. Specifically measured was the relationship between the size of a mass gathering and the frequency of patients seeking medical aid and the effects of certain event characteristics on this relationship.

Data were obtained through a retrospective literature review. Medline and CINHAL computerized databases were searched for English language articles using several keywords: “mass gathering”, “concert”, “festival”, “Olympics”, “crowd”, “riot”, “stadium”, “sports”, “games”, “papal”, and “football”. Only articles containing complete information on the number of spectators, number of patients, type, location, and duration of the mass gathering were included in the primary analysis. As available, additional information was added including the described weather patterns, number of patients transported to a hospital, and number of patients suffering a cardiac arrest. Thirty-five of the approximately 100 articles reviewed, met these criteria.

A Spearman Rank Correlation Coefficient was calculated for number of spectators and patients and a significant relationship was identified (p = 0.0001). Mann-Whitney U-tests indicated that papal masses (p = 0.04), rock concerts (p = 0.005), hot climatic conditions (p = 0.03) and events held in the British Commonwealth (p = 0.03) had a significantly higher frequency of patient visits. Significantly more cardiac arrests occurred at papal masses (p = 0.04) and sporting events (p = 0.0002).

Type of event, country, weather, and the size of the mass gathering had a significant effect on the numbers of spectators seeking medical care. A uniform classification scheme is necessary for future prospective studies of mass gatherings.
