A suicide bomber carried out the attack which killed six people in Turkey's capital late on Tuesday, and the type of explosives used point to Kurdish separatists, Ankara's governor said yesterday.

"The examinations showed the body parts belong to Guven Akkus, a man born in Sivas (Turkey) in 1979," Kemal Onal told reporters after an emergency government meeting called following the attack, the worst in the capital in at least a decade.

"It is understood the incident was caused by the explosion of a plastic (explosives) bomb on this person's body and the incident's style matches the methods of the separatist organization," the governor said.
