evidence: The Kuki and Paite ethnic tribes also entered into a cease-fire in March, which was signed in the presence of Manipur's Chief Minister. Both sides observed the cease-fire, and in October a peace accord between them was signed. In 1997 violence between the Kuki and Paite communities led to hundreds of deaths and the burning of many homes. Elsewhere in the northeast, the upsurge in Bodo-Santhal ethnic clashes, which began in April, intensified in July and August. More than 260,000 persons are currently living under poor conditions in relief camps in Assam's Kokrajhar, Gosaigaon, and adjoining districts as a result of the ongoing violence between Bodos and Santhals. The brutal killings of relatives of ULFA leaders renewed concerns about the situation in Assam. In Nagaland clashes between the Naga groups not participating in the cease-fire and the NSCN-IM occurred (albeit with less frequency than in 1997), leading to a number of deaths. There were also encounters between security forces and the NSCN-Khaplang faction throughout the year. [...] There are ethnic Chins among nonrecognized refugees in the northeastern states, particularly Mizoram. They and Chakma refugees in the state have been the targets of student-led demonstrations protesting their presence in the state. Recent tensions between security forces and Chin National Force (CNF) insurgents operating in Burma allegedly have resulted in detention, interrogation, and expulsion of some persons associated with the CNF. In Manipur the Manipur underground attempted to impose a $3 "tax" on all non-Manipuris above the age of 12 as the price for continued permission for them to live in the state.
