"It is insufficiently realized how, even apart from the 1971 massacre, the killing of Hindus has been a frequent and large-scale affair in Pakistan and Bangladesh. In East Bengal in February 1950, "from detailed information received, the conservative estimate of casualties was placed at 2,500 killed in the district of Barisal alone. Total casualties of Dacca and East Bengal riots were estimated to be in the neighbourhood of 10,000 killed". Ten days in May 1950 were enough to kill a similar number of Hindus; after this slaughter, a million Hindus fled East Pakistan within half a year."
