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, the Syrian Observatory for Human Rights said Tuesday.

The Kurdish-led Syrian Democratic Forces, who are backed by Washington, said Tuesday they had “driven out the regime gunmen who had infiltrated the Dheiban area” of Deir Ezzor province in the clashes which erupted on Monday.
