The blast, the deadliest in a string of bombings across Turkey this year, occurred Tuesday evening near a bus stop at a crowded park in Diyarbakir's impoverished Baglar district.

Seven of the victims were children.

Fourteen other people were injured and four remained in hospital Wednesday morning.

There was no immediate claim of responsibility for the attack.

Diyarbakir, a city of around one million people, is a hotbed of Kurdish separatist militancy.
