The defendants were on trial for “banditry”, the ministry said in a statement without identifying them.
But state-owned Tass news agency reported that they were accused of being part of the notorious GTA Gang, named after the violent game series Grand Theft Auto (GTA).
The group of Central Asian nationals was suspected of killing 17 motorists in the Moscow area between 2012 and 2014.
A lawyer who was at the building when the incident happened said that at least 20 shots were heard.
The security officers injured include a Russian National Guard member, who sustained a gunshot wound and was taken to hospital, and two police officers, who sustained various injuries, according to the ministry.
