On October 26, 2002, authorities interrupted negotiations and went on the assault on the building seized by terrorists during the presentation of the musical Nord-Ost. As a result of the special operation, 130 people were killed. According to the public organization “Nord-Ost” – 174 people. More than 700 were injured. The cause of the death of many hostages was the gas put into the room, the composition of which is still classified. The doctors who saved the lives of the victims did not have information about the necessary antidote.
In 2011, the European Court of Human Rights examined the collective complaint of victims of the terrorist attack and admitted that the Russian authorities violated the right to life and to a fair trial.
The court ordered Russia to pay monetary compensation to the families of the victims of the attack and to investigate the circumstances of the deaths of 130 people. However, the Investigative Committee of Russia refused to initiate criminal proceedings against persons responsible for the deaths during the assault.
