From 2009, the level of terrorism in Russia increased again. Particularly worrisome was the increase in suicide attacks. While between February 2005 and August 2008, no civilians were killed in such attacks, in 2008 at least 17 were killed and in 2009 the number rose to 45. In March 2010, Islamist militants organised the 2010 Moscow Metro bombings, which killed 40 people. One of the two blasts took place at Lubyanka station, near the FSB headquarters. Militant leader Doku Umarov—dubbed "Russia's Osama Bin Laden"—took responsibility for the attacks. In July 2010, President Dmitry Medvedev expanded the FSB's powers in its fight against terrorism.
