Hostage crisis in Moscow theater
October 23, 2002. Chechens capture 700 hostages at a Moscow theater. Russian security forces used an experimental gas to incapacitate the terrorist before they could detonate their suicide vests. Most of the terrorists were killed, but 120 of the hostages died from the gas.
On October 23, 2002, about 50 Chechen rebels storm a Moscow theater, taking up to 700 people hostage during a sold-out performance of a popular musical.
After a 57-hour-standoff at the Palace of Culture, during which two hostages were killed, Russian special forces surrounded and raided the theater on the morning of October 26. Later it was revealed that they had pumped a powerful narcotic gas into the building, knocking nearly all of the terrorists and hostages unconscious before breaking into the walls and roof and entering through underground sewage tunnels. Most of the guerrillas and 120 hostages were killed during the raid. Security forces were later forced to defend the decision to use the dangerous gas, saying that only a complete surprise attack could have disarmed the terrorists before they had time to detonate their explosives.
