US forces reportedly responded to an "unprovoked attack" by Syrian pro-regime forces at the Syrian Democratic Forces (SDF) headquarters on Wednesday, according to a statement from US Central Command (CENTCOM).

US-led coalition forces, who typically advise and assist SDF troops, conducted airstrikes against the Syrian forces who attacked their "well established" headquarters. No US special operations forces were injured during the attack according to reports from multiple news outlets.

"In defense of Coalition and partner forces, the Coalition conducted strikes against attacking forces to repel the act of aggression against partners engaged in the Global Coalition's defeat-Daesh mission," a CENTCOM statement said, referring to the alternative label for Islamic State militants.

The initial attack happened eight kilometers (about five miles) east of the de-confliction line on the Euphrates River.
