At least two people have been killed and several wounded in a car bomb explosion outside a courthouse in the Turkish city of Izmir.
Two attackers are believed to have been shot dead by police, who are now seeking a third assailant.
Turkey's Deputy Prime Minister, Veysi Kaynak said a much larger attack was apparently being planned based on the weapons found at the scene of the Izmir car bomb attack.
"Based on the preparation, the weapons, bombs and ammunition seized, it is understood that a big atrocity was being planned," Kaynak told reporters.
The attackers were reportedly carrying two automatic rifles, rocket launchers and eight hand grenades.
He said the attack, thought to have been carried out by Kurdish militants, would not stop Turkey's military involvement in Syria and Iraq.
