Nepalese police broke up a small Tibetan protest in Kathmandu and detained the demonstrators on the anniversary of a failed 1959 uprising against Chinese rule in Tibet.
The two men and three women waved Tibet flags and chanted, "Free Tibet, get out of Tibet, we want justice'' near the Chinese embassy visa office before being picked up by police.
Hundreds of riot police had stepped up security on Monday to stop any possible anti-China protests in Kathmandu and attempts by the Tibetan refugees to self-immolate to protest Chinese rule over their homeland, police spokesman Ganesh K.C. told the Associated Press news agency.
Police officers in riot gear guarded all the roads leading to the Chinese Embassy and its visa office in the center of Kathmandu.
Police are also keeping a close watch on the Boudhanath area in Kathmandu where most Tibetan refugees live. The area has many Buddhist monasteries and shrines.
Tibetan refugees in Nepal regularly demonstrate against Chinese rule over their homeland, but Nepal does not allow protests near the Chinese Embassy and other key areas, saying it cannot allow activities against friendly nations.
In the past, Tibetans in Nepal have attempted to storm the Chinese Embassy, while the Chinese government has repeatedly pressured Nepal to stop the protests.
Protesters are generally removed from the areas and detained for a few hours.
