A suicide gun and bomb attack on Istanbul’s Ataturk international airport, one of Europe’s busiest.
Three attackers were involved, with one reportedly opening fire with a Kalashnikov as they targeted an entry point to the terminal.
Recent bombings in Turkey have been linked to either Kurdish separatists or the so-called Islamic State group.
This looks like a major co-ordinated assault, the BBC’s Mark Lowen reports.
Ataturk airport was long seen as a vulnerable target, the BBC Turkey correspondent adds, reporting from a plane at the airport.
Many Israelis travel through Istanbul’s Ataturk international airport.
The Foreign Ministry in Israel said that it is examining whether there were Israeli casualties in the attack, but at this stage there is no indication that any Israelis were injured. Israeli passengers who were stranded at the airport following the attack were taken to nearby hotels until flights are renewed on Wednesday. Regardless, Israel has announced that it is sending an emergency medical team to help with the injured in Istanbul.
The Foreign Ministry has opened an emergency hotline at +972-2-5303155.
Turkish officials have confirmed that two suicide bombers detonated their explosives in the attack.
