Ambulances raced from Turkey to retrieve the dead and wounded, said the private Turkish Dogan news agency. Syrian activists of the Idlib News group listed 11 people wounded, including a five-month-old baby, who were rushed to Turkey.
The blast occurred near the Orient hospital in the rebel-held northwestern Syrian town of Atmeh, the activists reported. Atmeh hosts a sprawling camp for thousands of displaced Syrians. It wasn't immediately clear who operated the hospital, nor who may have carried out the bombing.
A February 20 car bomb targeted the Bab al-Salama border crossing in another part of northern Syria. The region is contested between rebel brigades and an al-Qaida breakaway group, the Islamic State in Iraq and the Levant.
