An explosives-laden vehicle has exploded and killed several people near a field hospital in the Syrian town of Atmeh, near the border with Turkey, activists said.
At least nine people were killed by the car bomb on Sunday, the Reuters news agency reported, citing Syrian activists on the ground.
The Britain-based Syrian Observatory for Human Rights and Turkey's state-run Anadolu agency both reported the incident in the northwestern Syrian town of Atmeh. Andalou said several people were killed and wounded.
The town of Atmeh hosts a sprawling camp for thousands of displaced Syrians, according to an Associated Press news agency report on the bombing.
The hospital is owned by Ghassan Aboud, a Gulf-based businessman who runs Orient Television, which said at least 10 people were killed.
It was not immediately clear who carried out the attack but Atmeh is in territory held by rebels fighting to overthrow Syrian President Bashar al-Assad.
