The question refers to a significant historical event following the 1971 Bangladesh Liberation War. After the surrender of Pakistani forces, a large number of Pakistani military personnel became prisoners of war (POWs) in Bangladesh and India. Bangladesh, having suffered immense atrocities during the war, intended to prosecute certain individuals for war crimes, genocide, and crimes against humanity. The specific number of Pakistani prisoners of war that Bangladesh sought to prosecute for these grave offenses was 195.
These 195 individuals were identified by Bangladesh as having committed serious crimes during the conflict. However, their prosecution ultimately did not proceed. Through diplomatic efforts, particularly the Delhi Agreement of 1973 between India, Pakistan, and Bangladesh, these 195 POWs, along with the vast majority of other Pakistani POWs, were repatriated to Pakistan without facing trial in Bangladesh. The numbers 193, 194, and 196 are incorrect figures related to the specific group of Pakistani POWs identified for prosecution by Bangladesh.
