Fighters loyal to the Syrian government have clashed with Kurdish-led forces in a mainly Arab district of eastern Syria, leaving 25 people dead in two days, a war monitor said Tuesday.
The Kurdish-led Syrian Democratic Forces (SDF), who are backed by Washington, said they had "driven out the regime gunmen who had infiltrated the Dheiban area" of Deir Ezzor province in the gun battles which erupted on Monday.
Earlier this month, the same area saw 10 days of fighting between the SDF and armed Arab tribesmen in which 90 people were killed.
Britain-based monitor the Syrian Observatory for Human Rights said the latest clashes erupted when pro-government fighters crossed the Euphrates river, which separates pro-government forces in southwestern Deir Ezzor from the SDF in the northeast.
