Turkey's Interior Minister Muammer Guler says the death toll in two car bomb explosions in a town near the border with Syria is up to 18.
The bombs exploded in the town of Reyhanli, just across the border from Syria's Idlib province on Saturday, also injuring 22 people.
He says one of the car bombs exploded outside the city hall while the other went off outside the post office.
Suspicion immediately fell on Syria, but there was no immediate confirmation of its involvement.
Turkey, which shares a more than 500-mile border with Syria, has been a crucial supporter of the Syrian rebel cause and Ankara has allowed its territory to be used as a logistics base and staging center for Syrian insurgents.
