Police in Nepal's capital have broken up a protest by Tibetan exiles in front of the Chinese embassy visa office, detaining more than 400, AP reported. Police official Ramesh Thapa says the Tibetan protesters tried to storm the visa office in Katmandu, violating a ban on demonstrations in the area. Thapa says some of the protesters, chanting anti-China slogans, reached the gates but were blocked by the police who detained them.
