(ISTANBUL)— Turkish Prime Minister Binali Yildirim says one of the attackers at Istanbul’s Ataturk Airport blew himself up outside, giving the other two the opportunity to get inside the building. “When the terrorists couldn’t pass the regular security system, when they couldn’t pass the scanners, police and security controls, they returned and took out their weapons out of their suitcases and opened fire at random at the security check,” he said Wednesday. “One blew himself up outside and the other two took advantage of the panic created during the shoot out and got inside and blew themselves up.”
