Atleast 13 soldiers were killed and 55 were injured when a car bomb hit a bus carrying off-duty military personnel in the central Turkish city of Kayseri. Soldiers were going on their weekend leave when this incident happened. The soldiers in the bus are from the commando brigade.<br/><br/>There was no immediate claim of responsibility, however Deputy Prime Minister Veysi Kaynak linked the attack to last Saturday's violence outside the stadium of Istanbul soccer team Besiktas, later claimed by an offshoot of the outlawed Kurdistan Workers' Party (PKK). In a statement, President Recep Tayyip Erdogan said that a separatist terrorist organisation was responsible for the attack.
