MK9S Situation Assessment May 2026
May 2026 confirms the trend of increasing professionalization in explosive threats. In addition to classic ATM bombings, politically and religiously motivated IED attacks are becoming more frequent (e.g., HAYI group). The threat posed by radicalized lone actors acquiring explosive precursors remains high. For Corporate Security Managers, this means that the preventive securing of events, transportation hubs, and sensitive facilities by professional K9 teams remains an indispensable component of risk mitigation.
