On 29 March 2010, two bombs exploded on the Sokolnicheskaya Line, killing 40 and injuring 102 others. The first bomb went off at the Lubyanka station on the Sokolnicheskaya Line at 7:56, during the morning rush hour. At least 26 were killed in the first explosion, of which 14 were in the rail car where it took place.

The Caucasus Emirate later claimed responsibility for the bombings.
