Death Toll at Turkish Border Bombing Rises to 13

Car bomb at customs gate at border to Syria

A mysterious blast ripped through a busy Turkish customs gate on the border with Syria on Monday, killing at least 13 people and wounding dozens, the Turkish government said.

Deputy Prime Minister Bulent Arinc, chief spokesman for the government, said a minivan traveling from Syria to Turkey exploded. He declined to call it a terrorist attack, saying the investigation was still ongoing.

"The type of explosive could not be determined as of this time," Arinc said.
