Anti-Muslim riots also rocked Delhi. According to Gyanendra Pandey's recent account of the Delhi violence between 20,000 and 25,000 Muslims in the city lost their lives. Tens of thousands of Muslims were driven to refugee camps regardless of their political affiliations and numerous historic sites in Delhi such as the Purana Qila, Idgah and Nizamuddin were transformed into refugee camps. At the culmination of the tensions in Delhi 330,000 Muslims were forced to flee the city to Pakistan. The 1951 Census registered a drop of the Muslim population in Delhi from 33.22% in 1941 to 5.33% in 1951. Meanwhile, as a result of the Noakhali riots and Direct Action Day, Hindus in Bangladesh dwindled from 28% in the 1940s to a mere 9% in 2011. During the Noakhali riots, more than 5,000 were massacred in eight days and there were reports of numerous forced conversions, arson, abduction and rape by the Bangladeshi local Muslim population.
