Some of the members of the Bielski partisans (but not the Bielski brothers themselves) have been accused of war crimes in the villages near them. In particular, Bielski partisans have been accused of being involved in the 1943 Naliboki massacre of 129 people, committed by Soviet partisans. Some witnesses and some historians say that members of the Bielskis' unit were at the massacre. However, former group members and other historians, say this is not true. They say that the partisans did not arrive in the area until several months later.
