REYHANLI, Turkey: Prime Minister Recep Tayyip Erdogan said yesterday Turkey would “not refrain” from responding to twin car bombings it has blamed on Syria but also said the government would be cautious and not be drawn into its neighbor’s civil war.

Saturday’s powerful bombings at a border town that is a main hub for Syrian refugees and rebels, was the bloodiest attack in Turkey in recent years. It escalated tensions between the two former allies and raised fears the conflict in Syria could engulf Turkey. The official death toll in the attacks stood at 46 but an Associated Press reporter saw authorities recovering at least one more body from a building on Monday.

Syria has denied being behind the attacks. Turkish authorities, however, said they had detained nine Turkish citizens with links to the Syrian intelligence agency in connection with the attacks, including a suspected ringleader.

Erdogan said yesterday Turkey had no doubt about Syria’s involvement and called Syria’s denial a lie.

“The incident is, with certainty, an incident connected to the regime,” Erdogan said. “Their world is based on lies.”

He said Turkey would not refrain from “giving the necessary response” but also indicated that the government wanted to act with restraint.

“We must not enter into a policy of tension,” Erdogan said. “We have to take steps that are required to be taken by great states. “

“We won’t fall for the trap, but we will give the necessary response at the necessary time. We would not refrain from this,” he said without elaborating.
