ANKARA, Turkey (Reuters) - Thirteen soldiers were killed and 48 more were injured when a car bomb hit a bus transporting off-duty military personnel in the central Turkish city of Kayseri on Saturday, one week after a twin bombing targeted police in Istanbul.

The blast is likely to further anger a Turkish public frustrated by a string of deadly bombings this year, several of which have been claimed by Kurdish militants, including last week’s, which killed 44 and wounded more than 150.

There was no immediate claim of responsibility, but Deputy Prime Minister Veysi Kaynak likened the attack to last Saturday’s dual bombings outside the stadium of Istanbul soccer team Besiktas, later claimed by an offshoot of the militant Kurdistan Workers Party (PKK).

“The car bomb attack resembles the Besiktas attack in terms of its style,” he told a group of reporters, adding the incident would not put Turkey off of its goal of fighting militancy.
