At least 13 people have died Saturday in a car bomb blast near a market in the Syrian border town of Tal Abyad controlled by Turkish forces, Ankara and a rights watchdog said.
Turkey's defence ministry said 13 civilians were killed and another 20 people injured in the attack, which it blamed on Kurdish fighters.
The Britain-based Syrian Observatory for Human Rights meanwhile reported the deaths of 14 civilians and Turkish-backed rebels in the explosion.
