At least seven people have been killed by remote-controlled car bomb in the city of Gaziantep in southeastern Turkey.
The explosives, placed near a police station, are believed to have been planted by Kurdish nationalists.
Dozens of wounded were carried to local hospitals amongst scenes of chaos.
"Kurdish militants are believed to be behind the attack," a security source told Reuters, although no such group has yet claimed responsibility.
The Kurdistan Workers Party (PKK) has long staged attacks in southeastern Turkey in an effort to destabilize the Turkish state and establish a Kurdish homeland.
Complicating matters is the deteriorating situation in neighboring crisis – Ankara believes that the Damascus regime may be supplying arms to PKK.
