An official says suspected Kurdish rebels have attacked a van in southeastern Turkey, killing four female civilians.
Gov. Musa Colak said the van was attacked with gunfire and hand grenades in Siirt province late Tuesday. One of the assailants was also killed when a grenade exploded prematurely in his hand.
The attack occurred close to a police training school, leading to speculation that the assailants may have mistaken the van for a police vehicle.
Kurdish rebels, who are fighting for autonomy from Turkey, have stepped up attacks on military and police, killing dozens of members of security forces and at least three other civilians since July.
On Tuesday, a car bomb explosion in the capital Ankara killed three people and wounded 34 other people. No one has claimed responsibility so far.
