Thirteen people, including policemen and soldiers, were injured on Thursday in an explosion in the western Turkish city of Izmir, the NTV news channel said.
The explosion ripped through a car on a road near a police residential complex where minibuses transporting police and soldiers were plying at the time, it said.
Seven police officers, three soldiers and three civilians were injured in the blast, the report said. The cause of the blast was not immediately clear.
Television footage showed dark smoke coming off a burning piece of wreckage in front of a police minibus as police cordoned off the area and warned civilians to stay away.
Izmir, which sits on the Aegean coast, has in the past been the target of bomb attacks especially by Kurdish rebels fighting the Ankara government for self rule in Turkey's southeast.
Thursday's explosion comes two days after a suspected suicide bomber pursued by police detonated a car in the southern city of Mersin, killing himself and wounding 12 officers.
Police have yet to make a statement on who was behind the attack.
