Shocking footage of car bomb attack
An explosion believed to have been caused by a car bomb in front of a courthouse in the western Turkish city of Izmir has wounded 10 people, a local official said.
Two of the suspected attackers were killed in an ensuing shootout with police.
District mayor Hasan Karadag told NTV television that one of the wounded was in a serious condition.
A firefight between three of the suspected attackers and police erupted after the explosion and two of the assailants were killed, he said.
Turkey's state-run news agency said police are looking for a third suspect, described as wearing a black coat and a white beret.
Several ambulances and police were dispatched to the scene.
The explosion occurred near an entrance used by judges and prosecutors, several media reports said.
The incident follows a string of attacks, carried out by Islamic State (IS) or by Kurdish militants, that have left Turkey on edge.
Thirty-nine people were killed in a nightclub attack in Istanbul during New Year's celebrations. IS claimed that attack.
