Soviet partisans
The Soviet partisans were involved in several massacres of Polish civilians, including at Naliboki, on May 8, 1943 and at Koniuchy on 29 January 1944. Soviet partisans and Red Army Officers have also murdered members of Polish anti-Nazi resistance after inviting them to "negotiations" in 1943, and also denounced them to the Germans, who then killed the Poles.
