Ten people have died in two explosions at Istanbul’s Ataturk airport.
Two attackers blew themselves up after police fired at them, an official said.
The state-run TRT television said an explosion hit a control point at the international arrival terminal of the airport.
Other media reported the sound of gunfire at the scene.
Eyewitness Ercan Ceyhan told CNN-Turk that he saw some 30 ambulances enter the airport.
The private DHA news agency said the wounded, among them police officers, were being transferred to Bakirkoy State Hospital.
Turkey has suffered several bombings in recent months linked to Kurdish or Islamic State (IS) militants.
The bombings included two in Istanbul targeting tourists – which the authorities have blamed on the IS group.
The attacks have increased in scale and frequency, scaring off tourists and hurting the economy, which relies heavily on tourism revenues.
