A suicide car bomber killed four people at a checkpoint in a Kurdish-controlled area of northeastern Syria on Tuesday, the Syrian Observatory for Human Rights said.
Observatory Director Rami Abdulrahman said the attack took place near the village of Tel Tamr, some 30 km from the Syrian-Turkish border. Syrian state TV also reported the deaths of four people in a car bomb attack in the area, but said it had taken place in the nearby town of Ras al-Ayn.
