ONE OF RUSSIA’S MOST wanted men, Chechen militant Doku Umarov, has claimed responsibility for the deadly bomb attack on Moscow’s Domodedovo airport last month which killed 35 people.

Investigators suspected Umarov’s involvement in the bombing after seeing a video released by Umarov on Friday – but made before the airport attack – which featured the man they suspect was the Domdedovo suicide bomber.

Authorities believe they have identified the suicide bomber and say he was a 20-year-old man from the North Caucausus.

In that video, Islamist militant Umarov warned of a year of “blood and tears” if Russia continues to preside over states in the North Caucasus.”

In a video posted on an extremist website more recently, Umarov said he ordered the attack in response to “Russian crimes in the Caucasus”, according to the BBC.

Russia Today reports that Russian legislators are expected to hold meetings today to discuss closer cohesion between security agencies in light of the Domodedovo attacks. Lax security at the airport was heavily criticised in the wake of the bombing, and President Medvedev fired several senior security and transport officials.

Umarov has previously claimed responsibility for the Moscow metro bombings in March 2010 which killed at least 40 people.
