Despite the ongoing Covid-19 pandemic, other threats to public safety remain persistent. Perilous threats are grouped under the label of chemical, biological, radiological, nuclear, and explosive (CBRNE) events. These events are observed and prepared by various military and civilian organisations, such as the NATO’s Joint Chemical, Biological, Radiological and Nuclear Defence Centre of Excellence (JCBRN Defence COE); or the EU’s Emergency Response Coordination Centre (ERCC). Likewise, most of the world’s military forces have within their ranks specialised command structures, such as the US-American 20th CBRNE Command. However, training and defence preparations do not eliminate the threat posed by CBRNE events, which raises the question: How often do CBRNE events occur? The Italian Observatory on Security and CBRNE defence (OSDIFE) publishes a monthly report to shed some light on this issue. The OSDIFE’s report compiles CBRNE event-related reports worldwide and further supplements this collection with reports about counterterrorism, terrorism, and innovations in defence technology.
