Syria's state TV has raised the death toll from a car bombing in a predominantly Kurdish town in the country's north, saying 22 people died and dozens were wounded.
The TV says the car blew up on the western edge of the town of Qamishli, near the Turkish border on Wednesday.
The Britain-based Syrian Observatory for Human Rights says the explosion targeted a center of the local Kurdish police and a nearby government building.
No one immediately claimed responsibility for the attack but the Islamic State group has carried out several bombings in Kurdish areas in Syria in the past.
The predominantly Kurdish U.S.-backed Syria Democratic Forces have been the main force fighting IS group in northern Syria and have captured wide areas from the extremists.
