Seven people, including six police officers, have been killed in a car bombing in the Turkish city of Diyarbakir.
Another 27 people were wounded in the explosion near a bus terminal in what is a mainly Kurdish city in southeast Turkey.
The bomb detonated as a special forces bus passed, according to state-run media.
It damaged cars and shattered almost all the windows of a nearby high-rise.
At least six ambulances deployed to collect casualties and security forces rushed to seal off the area.
The city has suffered renewed violence since a ceasefire between the outlawed Kurdistan Workers Party (PKK) and the government collapsed last July.
Turkish president Tayyip Erdogan said: "This shows terrorism's ugly face again. The determination of our security forces will, God willing, put an end to terrorism."
A PKK offshoot has claimed two car bomb attacks this year in the capital Ankara - including one on a military bus that killed 29.
There has been no immediate claim of responsibility following the Diyarbakir blast.
It is the second major attack Turkey has suffered in a fortnight after an apparent Islamic State suicide bomber killed four foreigners in Istanbul.
