Ankara: Several people were wounded on Saturday in a car bombing close to a public bus in the central Turkish city of Kayseri, television reports said, although the death toll was still unclear.
Initial television pictures showed that the bus had been reduced to a smouldering wreck by the impact of the blast. Ambulances were sent to the area after the explosion, the sources said.
The bus was carrying off-duty soldiers, according to reports, and was opposite a university campus when the explosion occurred.
The Dogan news agency said that the blast took place opposite the Erciyes University in the city. NTV television said that there could be fatalities as a result of the blast.
The explosion comes a week after 44 people were killed in an attack in Istanbul claimed by Kurdish militants.
Turkey has seen a spate of deadly bombings in 2016 blamed both in jihadists and Kurdish militants that have left dozens dead.
One of the main cities of central Turkey, Kayersi is a key industrial hub that is usually seen as a peaceful area.
It is well west of the southeast of the country that has been hit by months of deadly fighting between Kurdish militants and the security forces.
