Sat Dec 27 13:46:17 UTC 2025: ## US-Syria Cooperation Against ISIS Tested by Deadly Attack

Palmyra, Syria – A joint US-Syrian patrol was ambushed near Palmyra on December 13th, resulting in the deaths of two US soldiers and an interpreter. The attacker, a member of Syria’s security forces, was linked to ISIS by both US and Syrian officials, highlighting the complex security challenges facing the nation following the fall of the Assad regime in December 2024.

The incident underscores the growing cooperation between the United States and Syria in combating ISIS, especially after Syria joined the US-backed coalition against the group in November 2025. Experts note that intelligence sharing and support from the US have contributed to a significant decline in ISIS attacks within Syria. A report by Karam Shaar Advisory showed monthly attacks dropped from an average of 63 in 2024 to just 10 in 2025.

While the Al-Sharaa government is committed to the fight, a rapid security recruitment drive following the regime change has raised concerns about adequate vetting processes, leaving the system vulnerable to infiltration.

“The Palmyra attack points to structural flaws rather than a mere one-off event,” warned Nanar Hawash, a senior Syria analyst with the International Crisis Group.

Despite the improved security situation, analysts caution that ISIS remains a significant threat. While the group no longer seeks to control territory, its focus has shifted to destabilization. Targets include state security forces, religious minorities, foreign personnel, and the volatile situation in the SDF-controlled northeast, particularly the al-Hol and Roj prison camps holding numerous ISIS fighters.

“ISIS cannot hold cities or topple governments. But it doesn’t need to. Its strength lies in destabilisation,” said Hawach.

The attack raises questions about the sustainability of US confidence in the new Syrian government’s ability to provide security. Another similar incident could jeopardize the crucial US-Syrian cooperation necessary to contain the resurgent threat of ISIS.
