The suicide attackers who launched the deadly Istanbul airport assault were planning to take dozens of passengers hostage, Turkish media reported today, as CCTV of the bombers' faces emerged.

Turkish officials have pointed blame at the Islamic State jihadist group for Tuesday night's gun and bomb spree at Ataturk airport, which left 44 people dead including 19 foreigners.

"They say they are doing this in the name of Islam," President Recep Tayyip Erdogan said on a visit to Istanbul. "That has nothing to do with Islam. Their place is in hell."

State-run news agency Anadolu said 24 people had been detained in Istanbul in a string of raids over the attack over the past two days, including 15 foreigners.

Nine other suspected jihadists were rounded up in the western port city of Izmir, but officials declined to confirm a link with the bloodshed in Istanbul. AFP
