The War of Dagestan began on August 7, 1999, during which the Islamic International Brigade (IIPB) began an unsuccessful incursion into the neighboring Russian republic of Dagestan in favor of the Shura of Dagestan which sought independence from Russia. In September, a series of apartment bombs that killed around 300 people in several Russian cities, including Moscow, were blamed on the Chechen separatists. Some journalists contested the official explanation, instead blaming the Russian Secret Service for blowing up the buildings to initiate a new military campaign against Chechnya. In response to the bombings, a prolonged air campaign of retaliatory strikes against the Ichkerian regime and a ground offensive that began in October 1999 marked the beginning of the Second Chechen War. Much better organized and planned than in the first Chechen War, the Russian armed forces took control of most regions. The Russian forces used brutal force, killing 60 Chechen civilians during a mop-up operation in Aldy, Chechnya on February 5, 2000. After the re-capture of Grozny in February 2000, the Ichkerian regime fell apart.
