Beirut: Daesh launched an assault on the largely Kurdish city of Hasakeh in northeast Syria on Saturday, the Syrian Observatory for Human Rights said.

The attack came a day after Kurdish militia executed 20 civilians accused of supporting the extremists, the monitoring group said.

“Daesh fighters started an assault on Hasakeh city and reached the city’s southern periphery, where they are clashing with pro-regime forces,” said Observatory head Rami Abdul Rahman.

He said the pro-government National Defence Forces militia had blocked the Daesh advance on the city’s edges and reported heavy shelling.

Syria’s official news agency SANA said loyalist forces had “foiled a terrorist attack by Daesh on military points near Hasakeh”.

Control of Hasakeh, capital city of the province by the same name, is split between President Bashar Al Assad’s regime and Kurdish forces.

Abdul Rahman said at least 10 government loyalists had been killed, but he had no immediate information on Daesh casualties.

The Assyrian Network for Human Rights activist group said Daesh had launched “a new attempt at seizing control of the city” and seized one checkpoint on Hasakeh’s southwest edges.

“Hasakeh has been hit by mortar rounds since Saturday morning,” and a local church had been damaged, the Network said.

Elsewhere in Hasakeh province, Kurdish militia executed at least 20 civilians on Friday, including two children, after accusing them of being Daesh supporters, the Observatory reported.

The Britain-based monitor said Kurdish militia also burned and demolished homes of people it suspected of supporting Daesh near the flashpoint towns of Ras Al Ain and Tal Tamr.

The Kurdish People’s Protection Units (YPG) in Hasakeh have been battling Daesh extremists over a series of key towns in the province bordering Turkey.

Daesh on Friday killed 30 civilians trying to escape an advancing jihadist assault, Abdul Rahman said.
