A new CCTV video shows one of the attackers shooting a police officer several times and killing him before entering the elevators. Turkish officials have strong evidence that ISIS leadership was involved in the planning of the Istanbul airport terrorist attack, a senior government, according to sources that spoke to CNN. Officials believe the men — identified by state media as being from Russia, Uzbekistan and Kyrgyzstan — entered Turkey about a month ago from the ISIS stronghold of Raqqa in Syria, bringing with them the suicide vests and bombs used in the attack, the source said.
The death toll rose to 44 when a 3-year-old Palestinian boy hurt in the attack died, according to Palestinian officials. The boy’s mother died Wednesday, officials said. And Turkish state news agency Anadolu reported a Turkish man died at a hospital.
Those killed at the Istanbul airport had come from all over the world, but most of them were Turkish, including 10 airport employees, TAV Airports CEO Sani Sener said.
Saudi Arabia’s foreign ministry said six Saudis were killed and dozens more wounded.
Other fatalities included two Iraqis, one Tunisian, one Chinese, one Iranian, one Ukrainian, one Jordanian and one person from Uzbekistan, a Turkish official said. Three of the foreigners had dual Turkish citizenship.
One U.S. citizen suffered “minor injuries,” Homeland Security Secretary Jeh Johnson said Thursday.
