The Komsomolskoye massacre occurred following the Battle of Komsomolskoye (Chechen: Saadi-Kotar) during the Second Chechen War in March 2000. A prominent feature in the incident was the fate of a group of about 72 Chechen combatants who had surrendered on 20 March on a Russian public promise of amnesty, but had almost all either died or "disappeared" shortly after they were detained.
