A Chechen militant leader has claimed responsibility for twin suicide bombings on Moscow's Metro that killed 39 and wounded scores of others.
In a video statement recorded on Monday, Dokka Abu Usman, the leader of the Islamist "Emirate of the Caucasus", said the motive for the deadly blasts was revenge.
Usman said the attack was to avenge "the massacre by Russian invaders of the poorest residents of Chechnya and Ingushetia, who were picking wild garlic in the Arshty village on February 11, 2010, to feed their families".

In the clip, published on Chechen Internet site The Kavkaz Centre, he warned of fresh strikes against Russia, saying the troops stabbed their victims to death and then "mocked" their corpses.
He warned Russians that the "war will come to your streets, and you will feel it with your own lives and skins."
Warning of new attacks
Prime Minister Vladimir Putin on Tuesday ordered security forces to snare the masterminds of the metro bombings, saying they should be scraped out from the sewers.
Usman said Russians could no longer "idly watch the war in the Caucasus on their TV sets, watch it quietly, with no reaction to excesses and crimes committed by their gangs, which are being sent to the Caucasus under the leadership of Putin".
It was the first claim of responsibility for Monday's metro bombings in Moscow that killed 39 people. The authenticity of the video could not be independently confirmed.
Police have released grisly photographs of the two bombers' severed heads.
Russian authorities have said that the bombings, the first major terror attacks in Moscow in six years, were carried out by militants from North Caucasus.
Unconfirmed reports suggest the women arrived in Moscow from the Caucasus by bus early on Monday.
