ISTANBUL — A Turkish official says two explosions have rocked Istanbul's Ataturk airport, wounding multiple people.
The official said Tuesday it was unclear whether the explosions were caused by a suicide attack.
The official spoke on condition of anonymity in line with government protocol.
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.
Eye witness 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 group militants.
The bombings included two in Istanbul targeting tourists — which the authorities have blamed on the Islamic State group.
The attacks have increased in scale and frequency, scaring off tourists and hurting the economy, which relies heavily on tourism revenues.
