A bus transporting off-duty military personnel was struck by a car bomb on Saturday in Turkey’s Kayseri, killing 13 soldiers and injuring another 55. A car reportedly pulled up next to the bus at a red light before detonating. The bombing comes just a week after another deadly bombing in Istanbul claimed by Kurdish militants. In a statement issued after Saturday’s attack, Turkish President Tayyip Erdogan blamed “the separatist terrorist organization” for trying to “trip up Turkey, cut its strength and have it focus its energy and forces elsewhere.” “We know that these attacks we are being subjected to are not independent from the developments in our region, especially in Iraq and Syria,” he said, referring to the Kurdistan Worker’s Party, which Turkey considers a terrorist organization. No group has come forward to claim responsibility yet.
