Relatives of those who died during the Dubrovka Theatre raid are still seeking justice over Russian forces use of a deadly gas to end the siege.
Chechen militants stormed the Moscow venue on October 23rd ten years ago, taking 912 people hostage for three days.
One hundred and thirty theatre goers died when police pumped the gas into the ventilation system.
But this Russian security forces veteran said it was the only way to save at least someone.
To the anger of survivors and the victims’ families, who suspect a cover-up, officials have refused to reveal its contents.
According to a Levada Center poll, only nine percent of Russians believe the government has told the full truth.
Families of the dead will hold a ceremony at the theatre on Friday.
They will lay flowers to mark the end of the siege.
