Several people have been killed and more wounded by an explosion near a bus in the central Turkish city of Kayseri, security services say.

The bus was carrying off-duty soldiers, according to reports, and was opposite a university campus when the explosion occurred.

Turkey’s Dogan news agency said that the blast was caused by a car bomb.

The explosion comes a week after 44 people were killed by a bomb attack in Istanbul claimed by Kurdish militants.

TV images showed the bus reduced to a smouldering wreck by the blast.

Turkey has suffered a series of bombings in 2016 at the hands of both Kurdish militants and jihadists.
