Terrorism & Counterterrorism

Polish authorities arrested a 19‑year‑old student in late November in Lublin for allegedly preparing an ISIS‑inspired mass‑casualty bombing targeting a Christmas market, seizing items linked to Islam and digital media; he was remanded for three months as ABW continues its probe. Germany arrested five men on Dec. 12 over a suspected Christmas market attack plan in Lower Bavaria, and London’s Metropolitan Police increased armed patrols and public alerts after the Sydney Hanukkah shooting; U.S. officials separately disrupted a New Year’s Eve bombing plot in Southern California.
