Bangla College killing field is located in the Mirpur area of Dhaka , Bangladesh . In 1971 , during the Bangladesh Liberation War , the Pakistani army killed 3 million Bangladeshis with the help of some local collaborators . It has been claimed to be the largest genocide after World War II . Bangladesh officially became independent on 16 December 1971 , but the neighborhood of Mirpur was liberated from Pakistan Army and local Bihari people on 31 January 1972 , 45 days after the declaration of independence was signed . Mirpur was largely inhabited by Biharis who were against the secession movement , so genocide took place on a large scale . Mirpur was the last battlefield of the war . Bangla College is one of the largest killing fields in Bangladesh
