President Recep Tayyip Erdogan summoned the ambassadors from the five permanent members of the UN Security Council on Thursday, hours after Turkish warplanes launched airstrikes in northern Iraq as retaliation for an Ankara suicide car bomb that left at least 28 people dead Wednesday. “Turkey will not shy away from using its right to self-defense at any time, any place, or any occasion,” he said. Early Thursday, Prime Minister Ahmet Davutoglu declared the Syrian Kurdish YPG group was behind the suicide bombing, with help from the outlawed PKK movement, with 14 people detained in connection with the attack. Representatives from the YPG denied involvement. A car filled with explosives was detonated as military buses were passing by in an area close to parliament and military headquarters.
