Nepalese police have detained two Tibetan activists posting "anti-Beijing leaflets" ahead of a planned protest against Chinese rule of their homeland.Both were being held under public security laws that allow for preventive detention, though one faces charges of resisting arrest and assaulting police officers, Govind Pariyar, police chief in the Boudha area in Kathmandu where thousands of Tibetan refugees live, told AP.The activists — identified as Kelsang Nordup and Tashi Dawa — are members of the New Age Network, a group involved in organizing anti-China protests in Kathmandu, the report said.Dawa would likely be released after Thursday's planned protest, while Nordup could be jailed for a few months if convicted of the charges. Tibetan exiles in Nepal have regularly staged demonstrations in the streets of Kathmandu since a 2008 uprising in Tibet. Nepal has banned the gatherings, saying it cannot allow protests against friendly nations including China.Those violating or planning to violate the law are generally detained for a few hours to a few days before they are released
