(CNN) The organizer of the Istanbul airport massacre is a well-known terrorist who served as a top soldier in the ISIS war ministry, a U.S. official said.
Akhmed Chatayev, from Russia’s North Caucasus region, directed the three suicide bombers who killed 43 people Tuesday, said rep Michael McCaul, chairman of the House Committee on Homeland Security.
Turkish media reported that a man nicknamed “Akhmed One-Arm” organized the attack.
While his whereabouts are unclear, his ties to jihadist activities are well documented, McCaul said.
“He’s … probably the No. 1 enemy in the Northern Caucus region of Russia. He’s traveled to Syria on many occasions and became one of the top lieutenants for the minister of war for ISIS operations,” he told CNN’s Brianna Keilar.
