Two groups have claimed responsibility for three bomb attacks in Turkey in which two people were killed and 11 others injured.
Two hotels and a gas depot were targeted in the attacks.
Foreign tourists were among the injured.
A group claiming to have links with al-Qaeda said it carried out the bombings and warned of more to come.
An unknown Kurdish group also said it carried out the attacks.
Last November, more than 60 people were killed in four suicide bomb attacks on British and Jewish targets in the city.
