Pro-Syrian government forces, including alleged Russian Wagner Group mercenaries, crossed the Euphrates River de-confliction line and launched what U.S. Central Command described as an unprovoked attack on a well-established Syrian Democratic Forces headquarters where U.S. coalition service members were co-located, approximately 8 kilometers east of the agreed boundary.
On 7 February 2018, Operation Inherent Resolve coalition forces responded with air and artillery strikes against the attacking Syrian Armed Forces and pro-government militias near Khasham and Al Tabiyeh. The engagement resulted in significant casualties among the attackers, with estimates of Syrian troops killed at around 100, and disputed figures of Russian Wagner Group mercenaries killed ranging from 20 to over 200.
The battle drew intense international attention as reports emerged of Russian mercenary casualties, making it widely characterized as the first deadly confrontation between Russian and American citizens since the Cold War. Russia officially denied having service members in the area, and the exact death toll of Russian nationals remained contested, with estimates ranging from 20 to 200 depending on the source.
