This escalated up until the early 1990s, and was followed by the forceful expulsion of Nepali ethnic minority citizens from the southern part of Bhutan. The main purpose of this was the fear that revolt mirrored images of the Gorkhaland movement stirring up in the neighboring state of West Bengal, and fueled fears of a fate similar to the Kingdom of Sikkim where the immigrant Nepalis population had overwhelmed the small native population of the kingdom, leading to its demise as an independent nation. The Bhutanese security forces were accused of human rights violations including torture and rape of political demonstrators, and some Lhotshampas were accused of staging a violent revolt against the state.  According to the UNHCR, an estimate of 107,000 Bhutanese refugees living in seven camps in eastern Nepal have been documented . After many years in refugee camps, many inhabitants moved to other host nations such as Canada, Norway, the UK, Australia, and the US as refugees. The US admitted 60,773 refugees from fiscal years 2008 to 2012.
