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, Mahmut Demirtas told Anadolu news agency.
He said the suspect’s car license plates had been identified and a female attacker was suspected.
There was no immediate claim of responsibility.
Kurdish, Islamist and leftist militants have all carried out bombings in recent years.
Windows were blown out and parts of the facade of the building, roughly six floors high, were torn off.
Adana, about 40km (25 miles) from the Mediterranean coast, is about 16km from Incirlik Air Base, which the US military uses to launch attacks against so-called Islamic State militants in Syria.
In March, the US ordered families of US defence personnel and diplomats out of Adana and two other provinces because of security concerns.
“This accursed terror continues to target our people,” Turkey’s EU Affairs Minister Omer Celik, a ruling party MP from Adana.
“We will fight against terror until the very end in the name of humanity,” he added.
