An explosion in the eastern Turkish city of Igdir has wounded at least 12 people.
Officials say a bomb in a truck parked near a police facility exploded Saturday, and that two of those wounded are in serious condition.
No one has claimed responsibility for the blast.
Turkey has been on edge since a bomb killed 10 people in the southeastern city of Diyarbakir earlier this month. Authorities in Ankara have blamed the Kurdistan Workers Party for such incidents in the past.
The country's Kurdish-dominated southeastern region has seen a surge of clashes between separatist Kurdish guerrillas and Turkish troops. Many of the guerrillas belong to the Kurdistan Workers Party, P.K.K., which launched its armed struggle for an independent Kurdish state in 1984.
The fighting has claimed the lives of more than 30,000 people.
