Kurdish, Islamist and leftist militants have all carried out bombings in recent years.
A car bomb outside the governor’s office in the Turkish town of Adana has killed two people and injured 16, the governor has told state-run media.
The vehicle exploded in the car park close to the office entrance in the southern town.
The suspect’s car license plates had been identified and a female attacker was suspected.
There was no immediate claim of responsibility.
