Tbilisi: Chechen militant Akhmed Chatayev, who is suspected to have organised the Istanbul airport attack last year, blew himself up while two others were shot dead during clashes with security forces near here on November 22, Georgian officials said. Chatayev was regarded by European intelligence agencies as one of the key recruiters for extremists in Europe. He is said to have made living arrangements for the three bombers before the Istanbul airport attack which left 46 dead and scores injured. In 2015, he was placed on a terror black list by the UN Security Council and US Treasury for suspected ties to the Islamic State (IS) and al Qaeda. While no group claimed responsibility for the Istanbul attack, Ankara blamed it on IS.
