Istanbul: Two people were killed and 16 wounded on Thursday in a car bomb explosion outside a local government building in the southern Turkish city of Adana, officials said.
The bomb exploded in the car park of the governor's office for the Adana region, close to the vehicle entrance, the governorate said in a statement.
The explosion sparked a fire, and a cloud of dark smoke spewed into the sky.
The force of the blast caused damage to the governorate itself, the state-run Anadolu news agency said, describing the blast as a "terror attack".
"Two people were killed and 16 were wounded," the governor of Adana, Mahmut Demirtas, was quoted as saying by Anadolu.
"A vehicle blew up at 8.05 am (0505 GMT) at a parking lot next to the entrance of the governor's office," Demirtas said.
The attack is believed to have been carried out by a woman, the governor said, without providing further details of the nature of the blast.
As has been the case with previous attacks, the Turkish authorities immediately slapped a broadcast ban on footage of the blast.
"This accursed terror continues to target our people," Turkey's EU Affairs Minister Omer Celik, a ruling party MP from Adana, wrote on Twitter.
"We will fight against terror until the very end in the name of humanity," he added.
With a population of almost two million, Adana is one of Turkey's largest cities, lying around 100 kilometres (60 miles) from the Syrian border.
The US consulate in Adana in September had warned its citizens of a potential security threat targeting US-branded hotels there.
Incirlik air base, located just outside Adana, is used by American and coalition forces as a hub for air raids against Islamic State (IS) jihadists in neighbouring Syria.
Turkey has already been hit by a bloody year of militant attacks in its two biggest cities that have left dozens of people dead and put the country on a high security alert.
Kurdish militants have twice struck in Ankara in deadly attacks, while suspected IS suicide bombers have hit Istanbul on three occasions.
In June, 47 people were killed in a triple suicide bombing and gun attack at Istanbul's Ataturk airport, with authorities pointing the finger at IS.
Fifty-seven people, 34 of them children, were killed in August in a suicide attack carried out by a bomber linked to IS jihadists at a Kurdish wedding in the southeastern city of Gaziantep.
The country is also still reeling from a failed 15 July coup blamed on the US-based Islamic preacher Fethullah Gulen that has been followed by a relentless purge of his supporters from all state institutions.
Battle against PKK
There was no immediate indication who could be behind the latest attack.
The Turkish military has stepped up operations against Kurdish militants after a fragile ceasefire broke down in 2015. There has been a dramatic surge in violence that so far shows no sign of ending.
The outlawed Kurdistan Workers' Party (PKK), designated as a terror group by Turkey and its Western allies, generally concentrates its attacks in the southeast of the country.
While it is located strategically in southern Turkey, Adana lies to the west of the southeastern region that has been the main theatre of conflict with the PKK.
