Authorities have detained nine Turks believed to have links to Syria in connection with bombs that killed 46 people. Elsewhere Sunday, Syrian rebels freed peacekeepers captured on the Israeli-occupied Golan Heights.
The nine detained included the mastermind of the attack, said Turkish Interior Minister Muammer Guler, who added that he expected more arrests. Saturday's blasts have raised concern that Syria's bloody civil war is crossing into Turkey.
"This incident was carried out by an organization which is in close contact to pro-regime groups in Syria and I say this very clearly, with the Syrian mukhabarat," Guler said, using the Arabic word for intelligence. "We have determined that some of them were involved in the planning, in the exploration and in the hiding of the vehicles," he added.
