Izmir: An explosion believed to have been caused by a car bomb in front of a courthouse in the western Turkish city of Izmir on Thursday wounded some 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 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 the Islamic State group 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. The IS group claimed that attack.
