The Syrian Observatory for Human Rights said on Tuesday that 25 people, most of them pro-regime gunmen, were killed in several hours of clashes with the Syrian Democratic Forces in the vicinity of the towns of Hawaij Dhiban, Dhiban and Tayana in Deir Ezzor province in eastern Syria.

Following the end of Monday's clashes, the Syrian Democratic Forces (SDF), an alliance of U.S.-backed Kurdish and Arab factions, stepped up their deployment in the area.

On Tuesday morning, it announced the "expulsion of regime gunmen from the town of Dhiban hours after they infiltrated" from the areas under their control.

From the early hours of dawn, the area was relatively calm, with sporadic clashes heard.
