A bomb in the southeastern Turkish city of Diyarbakir Tuesday evening killed seven people and injured 17 others, the local governor's office said.
Authorities said the bomb was made from powerful explosives and was set off by a cell phone timer. It was not immediately known who placed it.
Diyarbakir Deputy Gov. Ahmet Aydin said children were among the killed and that two of the injured were in serious condition at a local hospital. Local news stations said five of the seven killed were children.
The blast apparently took place near an elementary school, a Kurdish news agency reported.
Diyarbakir is Turkey's largest Kurdish-majority city, and the explosion comes as Kurdish rebels fighting for autonomy in the region have stepped up their attacks.
It is the third suspected bomb attack of the day.
Ten people, 7 of which are children, are dead, and at least 17 injured as a bomb went off in , Turkey. Police say that the bomb was set off by a timer on a mobile phone. The blast happened inside a park in the Baglar region of Diyarbakir.

A group called the Kurdistan Freedom Falcons or TAC has claimed to be responsible for the blasts. The group threatened Turkey last week when it posted a message on their website saying that they would turn the country "into hell."

"Our grief is great for the victims of this terror, especially as our children have been the victims," said Recep Tayyip Erdogan, the Turkish Prime Minister.
