In January 2010 , in a statement about the upcoming " military actions " , Umarov said the re-created Riyad-us-Saliheen Brigade of Martyrs will now operate in the Russian cities outside the Caucasus and " the war will come to their homes " , possibly indicating the new wave of bombings such as those conducted by the group in Moscow and elsewhere in 2002 – 2004 under Basayev 's orders . On 31 March 2010 , Umarov claimed responsibility for personally ordering the Moscow Metro bombings which took the lives of 40 civilians . He warned that more attacks were to come on Russian soil because of perceived repressions of Chechnya by Prime Minister Putin . On 7 February 2011 , Umarov claimed responsibility in a video posted online for ordering a suicide bombing at Domodedovo International Airport , Russia 's busiest airport . The bombing killed 36 people , and was described by Umarov as a " special operation " targeting the Russian society and Putin personally . His practice of claiming responsibility for such attacks resulted in some media dubbing him " Russia 's bin Laden . " On 3 February 2012 , Umarov made an about-face again . In a video posted online , ordered his subordinates to halt attacks on the civilian population of Russia , while leaving military and security personnel as legitimate targets . Umarov gave this order in response to nationwide protests against the Russian government . In June 2013 , however , Umarov , accompanied by his deputy Aslan Byutukayev , called for his followers in and outside the Caucasus ( in particular in Tatarstan and Bashkortostan ) to use " maximum force " to ensure the 2014 Sochi Winter Olympics do not take place , claiming that Russia 's " barbaric actions " in the region had forced him to retaliate . Umarov said : " Today we must show those who live in the Kremlin … that our kindness is not weakness . They plan to hold the Olympics on the bones of our ancestors , on the bones of many , many dead Muslims buried on our land by the Black Sea . We as mujahideen are required not to allow that , using any methods that Allah allows us . " Russian state mass media did not report his threat , but Russia 's anti-terrorist committee said it was taking measures to " protect Russian citizens " and was " paying special attention to questions of preparation for hold major sporting events of a global scale " while the Sochi 2014 Organising Committee announced that security would be a top priority . In October , a Caucasian '' shahidka '' woman blew up a bus in Volgograd
