A Chechen militant leader has claimed responsibility for the bombing that killed 36 people at Russia's biggest airport last month. Warlord Doku Umarov appears in a 16-minute video posted online in which he says the suicide bombing at Moscow's Domodedovo airport was carried out on his orders and warns of more attacks to come, AP reports.
"You see this special operation carried out by my order. More special operations will be carried out in the future," Umarov says in the video. "Among us there are hundreds of brothers who are prepared to sacrifice themselves" in further attacks. "We can at any time carry out operations where we want," he adds. Chechen rebels, who seek to establish an independent Islamic state in the Caucasus, also claimed responsibility for the Moscow subway bombing last year. (Read more Doku Umarov stories.)
