In particular, in the Luhansk region documentary evidence of participation in the activities of the LPR terrorist organization of Russian citizen Igor Grigorov (born 1972) was revealed. He was a commander of a BMD 1 squad.
Grigorov's military card shows his enrollment into the military service on July 7, 2014. This is another indication that the Russian Federation enlists and sends its troops to fight in the territory of Ukraine, against Ukrainian citizens, the statement says.
All the evidence has been included into the relevant criminal proceedings.
