World News: Chechen rebel leader claims responsibility for bombing
The Kavkaz Centre website received the video late yesterday. It was not clear when or where the video was recorded.
The January 24 attack at Moscow's Domodedovo Airport killed 36 people.
Russian investigators said the bomber was a 20-year-old man from the Caucasus region that includes Chechnya, but have not released his name or other details.
"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, wearing a camouflage uniform and a skullcap.
"Among us there are hundreds of brothers who are prepared to sacrifice themselves" in further attacks, Umarov says in the video.
"We can at any time carry out operations where we want," he added.
Chechen rebels have fought two full-scale wars against Russian forces since 1994.
