Еще 40 armed militants stormed the Dubrovka Theatre in southern Moscow during a performance of the Nord-Ost musical. Some 900 people, including theatre workers, performers and audience members, were taken hostage. The militants claimed allegiance to the separatist movement in Chechnya and demanded the withdrawal of Russian forces from the region. After almost three days, Russian special forces began an assault, filling the building with knock-out gas. All the militants were killed during the raid, as well as 130 hostages, some of whom are believed to have died from the effects of inhaling the gas.
