An explosion has targeted a police station in the southern Turkish city of Adana, causing damage and shattering nearby windows, local media say.
According to the private Dogan news agency, the blast took place at 7:10 p.m. on a street close to the police station in the city's Seyhan district on Thursday.
The bomb was placed beneath an electrical pole by a person wearing a mask. It shattered nearby windows and was heard in other parts of the city.
Adana Police Chief Selami Yildiz said that the explosion was caused by a "sound bomb" designed to make a loud noise but not cause any casualties.
"We believe it was a home-made bomb, like a sound bomb," the official Anadolu agency quoted Yildiz as saying. "We are continuing our inspections," he added
Police teams have launched a major manhunt for the perpetrator.
In recent years, Turkey has suffered a wave of deadly attacks carried out by Kurdish militants or Takfiri Daesh terrorists that have killed hundreds of people.
