At least eight people died when a car bomb exploded near a police station in the southeast of Turkey.
Dozens more were said to be injured in the blast in Gaziantep, near the Syrian border.
There was no immediate claim of responsibility for the blast, but Kurdish militants are active in the area.
The fight between Turkish security forces and Kurdish rebels, who seek autonomy in Turkey's predominantly Kurdish southeast, has intensified in recent weeks.
Television footage showed firefighters attempting to douse a fierce blaze that gutted several vehicles.
NTV television said eight people died and as many as 50 were wounded.
Earlier, CNN-Turk television reported seven deaths, citing local authorities.
The blast comes at a delicate time for the government of Prime Minister Recep Tayyip Erdogan.
His government is providing refuge to tens of thousands of Syrians who have fled the conflict in their country, and is seeking the removal of Syrian President Bashar al-Assad.
Within its borders, the Turkish state has granted more cultural rights to Kurds as a means of easing the long-running conflict with a significant portion of the ethnic minority, but there is still a great deal of distrust between the government and many Kurds.
The Kurdish rebel group PKK operates from bases in the mountains of northern Iraq, and Turkish jets have periodically conducted bombing raids there.
