"On the borders of what was to become East Pakistan, Hindu-Muslim violence in 1947 was far smaller in scale. What happened there was that after a relatively peaceful transition to independence, the Partition process of religious cleansing took place anyway but drawn out over decades. During this "prolonged Partition", there has been a constant trickle of Hindu refugees from East Bengal to India, which became a flood in times of crisis. The biggest crisis was of course the Bangladesh war of 1971, when the Pakistani army and its Bengali and immigrant-Bihari collaborators hunted down Hindus along with Muslim Bengali nationalists. The official death toll as claimed by the Bangladeshi government was 3 million; foreign observers settle for 1.5 million. All disinterested observers agree that Hindus were the first and largest among the victim groups. As for the Muslim victims, they were not killed by Hindus but by Pakistanis and their Jamaat-i-Islami collaborators who killed them for not being Muslim enough."
