At least 22 Syrians were killed in a triple suicide car bomb attack in northeastern Syria, the London-based Syrian Observatory for Human Rights (SOHR) said Friday in a revised toll.

The monitor group said the attacks targeted the town of Tal Tamr in Syria's Hasakeh province.

A bomb detonated next to a post manned by Kurdish security forces and that members of the force were believed to have been killed.

Another blast took place in front of a hospital, where four women and a doctor were killed.

The SOHR said dozens of people had been injured in the blasts and warned that the toll could rise further.

Tal Tamr, in Hasakeh's Khabur region, is controlled by Kurdish forces and has been targeted in the past by Daesh terrorists.
