Burmese Indians came from various groups from different parts of India, including Tamils, Telugus, Hindi speakers, Bengalis, Gujaratis, Oriya, and Punjabis. Today they form approximately 2% (about 950,000) of the population, according to the CIA "World Factbook 2006", although exact figures do not exist due to uncertainties over census results and methods in Myanmar. Disaffected young Indians often flee the cities and join ethnic resistance movements. The All Burma Muslim Union whose members consist largely of Muslims of Indian origin is routinely labelled by the government as "Muslim terrorist insurgents". It operates alongside the Karen National Union which has a militant wing and, despite a swelling of its ranks following anti-Muslim riots in the eighties, remains a very minor force.
