A suicide bomber identified as the companion of Badia region security official Abu Jaber Sufyan detonated explosives against a US military delegation at Palmyra's security headquarters just after 1:46 PM UTC on December 13, 2025, killing two US personnel and wounding others, according to former Al-Nusra Front leader Saleh Al-Hamawi cited by Syrian Observer. Al-Hamawi, posting under the name “The Exponent of the Conflict in the Levant,” revealed these details of the attack in the past 30 minutes. A separate X post by @AnalyticaCamil1 attributed the casualties to Daesh, quoting Al-Jazeera's earlier report of a shooting involving US troops in the Palmyra area with casualties. The incident occurred as US forces entered Palmyra for the first time on patrol with heavy security including fighter jets, building on Al-Jazeera reports from before 1:46 PM UTC shared via @AJArabic. This marks an unprecedented US troop presence in the city, per @QalaatAlMudiq.
