The NKVD prisoner massacre in Sambir was a Soviet war crime conducted by the NKVD in the city of Sambir, then located in occupied Poland (now in Ukraine). In the last days of June 1941, following the German invasion of the USSR, the Soviets executed an estimated 500 to 700 prisoners held in the Sambir prison. The majority of those executed were Ukrainians and Poles. During the latter stage of the massacre, some prisoners actively resisted, which resulted in saving their lives. This atrocity was one of several prisoner massacres carried out by the Soviet secret police and army during the summer of 1941.
