A double suicide car bombing at the Bab al-Hawa border post between Syria and Turkey killed at least 16 people and wounded others on Monday, a monitoring group said.

The opposing UK-based Syrian Observatory for Human Rights said the blasts hit on Monday afternoon, with one car detonating at a checkpoint just outside the crossing and another inside the post.

The observatory added a number of the wounded were in critical condition and the toll was expected to rise from the attack in the northwestern province of Idlib.

The observatory said that the culprits are likely to belong to ISIL, despite the latter's denial of carrying out the blasts.
