At least seven US-supported Kurdish fighters have been killed and 18 wounded in a drone strike on a US base in eastern Syria by the Iran-backed militia Islamic Resistance in Iraq.
The Kurdish-led Syrian Democratic Forces confirmed the attack on their commando academy at the base.
Six of our fighters were martyred during a terrorist attack by a suicide plane originating from areas controlled by Syrian regime mercenaries, targeting a training academy in the al-Omar oilfield east of Deir ez-Zor.
Syrian activists later reported the death of a seventh fighter.
The Islamic Resistance of Iraq also claimed the January 28 drone strike that killed three US troops and injured 34 at at outpost in Jordan. The Americans responded four days later with 85 strikes on militia positions in Syria and Iraq.
Al-Omar is the largest base in Syria of the US-led coalition including the SDF, created in 2014 to expel the Islamic State from northern and eastern Syria.
About 2,500 US troops are still deployed in Iraq and about 900 in Syria, where much of the northeast is controlled by a Kurdish administration.
