For years, Umarov had been the top terrorist leader in Russia. He had taken responsibility for several attacks on civilian targets since 2009, including the 2010 Moscow Metro bombings and the 2011 Domodedovo International Airport bombing. In 2012, Umarov ordered his followers to halt attacks on the civilian population of Russia, while leaving military and security personnel as legitimate targets. In July 2013, however, he announced the end of this moratorium and calling on Islamic insurgents in the Caucasus and beyond to forcibly prevent the holding of the Sochi 2014 Olympics. Umarov was internationally wanted by the government of Russia and United States. In 2011, the United Nations Security Council's Al-Qaida and Taliban Sanctions Committee added Umarov to the list of individuals allegedly associated with al-Qaeda and Taliban.
