The attack took place Saturday during a training session at the Western Military District, according to TASS, which cited the Russian Defense Ministry. The gunmen were said to be from former Soviet states. Russian officials have branded the attack an act of terrorism.

“The incident occurred during a shooting training session with volunteers preparing for a special operation. The terrorists attacked the personnel of the unit with small-arms fire.”
According to TASS, two individuals who committed the “terrorist act” were killed in retaliatory fire at the training ground.
