The Moscow region Prosecutor's Office said on May 25 it has filed a lawsuit to recognize crimes committed by Nazi troops in 1941-1942 in the area as war crimes and genocide. The move comes amid international calls to recognize Moscow’s ongoing invasion of Ukraine as genocide of Ukrainians. In October, a court in the Russian city of St. Petersburg (formerly Leningrad), recognized the 1941-1944 siege of the city as a genocide. In January, President Vladimir Putin said it is "extremely important" to recognize Nazi crimes in the Soviet Union during World War II as genocide.
