The total number of people killed in East Pakistan is not known with any degree of accuracy . Bangladeshi authorities claim that 3 million people were killed , while the Hamoodur Rahman Commission , an official Pakistan Government investigation , put the figure as low as 26,000 civilian casualties . According to Sarmila Bose , between 50,000 and 100,000 combatants and civilians were killed by both sides during the war . A 2008 '' British Medical Journal '' study by Ziad Obermeyer , Christopher J. L. Murray , and Emmanuela Gakidou estimated that up to 269,000 civilians died as a result of the conflict ; the authors note that this is far higher than a previous estimate of 58,000 from Uppsala University and the Peace Research Institute , Oslo
