Biharis supported the Pakistan Armed Forces during the 1971 Bangladesh Liberation War, comprising majorities in armed paramilitary groups such as Al-Shams, Razakars and Al-Badr (held responsible for the genocidal campaign against Bengali nationalists, civilians, religious and ethnic minorities). News outlets such as the BBC have published death-toll estimates by independent researchers varying from 200,000 to 500,000. Scholars such as R. J. Rummel and Matthew White estimate the total Bengali civilian death toll at 1.5 million. The casualty figure estimated by Pakistan is 25,000, as reported by the Hamoodur Rahman Commission.
