Moscow: Spilling his guts about the deadly bomb attack last month on a Moscow airport, Chechen warlord Doku Umarov claimed that he ordered to conduct the incident which was a response to Russian crimes in the Caucasus, reported BBC.

The attack on the arrivals area of Domodedovo international airport on 24 January had left 36 people dead and 180 injured.

Umarov is leader of the Caucasus Emirate, an Islamist militant outfit spanning the North Caucasus, and is one of the few prominent Chechen rebels still active, having served as security minister in the Chechen separatist government from 1996-99.

Similar suicide attacks would continue, he threatened, speaking in Russian.

He has also claimed the March 2010 suicide bombings on the Moscow Metro in which 39 people died, and the November 2009 bombing of a train from Moscow to St Petersburg that left 26 dead.

The video, On my orders, which appeared on the Kavkaz Tsentr website is dated 24 January, the day of the attack.

Umarov said in the video: "This special operation was carried out on my orders and, God willing, special operations like it will continue to be carried out."

He argued that Muslims are under attack all over the world, talking at length about the situation in Sudan, and condemns "Zionist and Christian regimes led by Israel and America".

Russian investigating officials said the suicide bomber who struck at Domodedovo Airport was a 20-year-old man from the North Caucasus.

Russian President Dmitry Medvedev fired several officials including a regional transport chief and a Moscow police deputy head after the bombing, accusing them for poor security.
