Police raided houses this evening in a major security crackdown in Diyarbakir, the largest city in Turkey's mainly Kurdish southeast, after a bomb blast killed 10 people, five of them children.
It was the bloodiest attack in Turkey since suicide bombers killed more than 60 people in Istanbul in November 2003 and the latest in a series of explosions in Turkish cities, including coastal resorts, which have killed at least 15 people.
No one claimed responsibility for the blast late yesterday at a bus stop in the city, in the heart of a region that has witnessed 22 years of conflict between Turkish security forces and rebels fighting for a Kurdish state.
The local governor's office put the death toll at 10, with 15 injured. Police had earlier said the blast killed 11 people.
Among the dead were a mother, her four children and her sister, the state Anatolian news agency reported.
