An unspecified number of people have been wounded in at least two explosions at Ataturk Airport, located just outside of Istanbul in Turkey.
Turkish officials say they haven't confirmed whether the blasts were suicide bombers or bombs planted at the site, but the incident is believed to be a militant attack.
There have also been reports of gunfire at the scene, and witnesses told Reuters that gunmen opened fire from an airport car park.
Footage has emerged apparently showing terrified commuters taking cover at the airport.
