A car bomb wounded nine people in the eastern Turkish province of Tunceli on Monday near a housing block for civil servants working at a local courthouse, security sources said.
Three of those wounded were in critical condition after the bomb was detonated near the lodgings in the district of Ovacik, the sources said. Television images showed the remains of a vehicle burning on the road and smoke rising from damaged buildings.
Turkey has seen a series of such attacks over recent months, including last week when a car bomb ripped through a police bus in central Istanbul near the main tourist district, a major university and the mayor's office.
Kurdish militants claimed responsibility for that attack. The militants have increasingly staged bombings outside the largely Kurdish southeast, where they have been waging an armed insurgency for three decades.
Tunceli is a mainly Kurdish province but lies further north than where most of the fighting between Kurdish militants and the security forces has been centered in recent years.
Most of those hurt in the latest attack were civilians, security sources said. Authorities have stepped up security measures around the town, they added.
Islamic State has also been blamed for suicide bombings including two in Istanbul this year.
