BEIRUT: Syria regime forces ousted Daesh (ISIS) from a town near the border with Iraq on Monday after days of clashes to end a deadly incursion there, a monitor said.

On Friday, the militants used at least 10 suicide bombers in their offensive on Albukamal, quickly overrunning several of its neighborhoods, the Syrian Observatory for Human Rights said.

It was the biggest attack on the town in the eastern province of Deir al-Zor since the militant group lost it to regime forces in November 2017, the Britain-based monitor said.

On Monday, “regime forces and their allies regained control of the whole town of Albukamal after expelling Daesh from its northern and northwestern parts,” Observatory head Rami Abdel-Rahman said.

After loyalist forces tried to surround them, the militants fled back into Syria’s vast Badiya desert, which stretches from the country’s center to the border with Iraq, he said.

Violent clashes since Friday have killed at least 48 regime forces and allied fighters, as well as 32 militants including the 10 suicide bombers who led the initial raid.

Daesh has ramped up its attacks on fighters loyal to President Bashar Assad since the extremist group withdrew from its last bastion in the capital last month.

The militants were bussed out of the southern suburb of Yarmouk to parts of the Badiya desert under a secretive evacuation deal with the regime.

Daesh has lost much of the “caliphate” it declared in 2014 in Syria and neighboring Iraq, but still holds slithers of land in the desert and east of the country.

In eastern Syria, regime forces hold land west of the Euphrates River.

A Kurdish-Arab alliance backed by the U.S.-led coalition, meanwhile, has been fighting extremists in a tiny pocket on its eastern banks and another to the north in the northwestern province of Hassakeh.
