A homicide bomber has reportedly detonated explosives inside a car when stopped by police, killing two suspected militants and wounding six policemen in Turkey.

A private Turk television station says police stopped the car Tuesday on a highway on the outskirts of the southern city of Mersin. TV footage shows firefighters trying to extinguish flames at the scene.

The report says police had been following the car after a tip. Police have confirmed the explosion, saying there were casualties.

There has been no immediate claim of responsibility. Kurdish, Islamic and leftist militants are active in Turkey.
