"Dozens of ethnic Tibetans have set themselves on fire in heavily Tibetan regions since March 2011 to protest what activists say is Beijing's heavy-handed rule there. U.N. human rights chief Navi Pillay urged Chinese authorities on Friday to better address grievances expressed by Tibetan people and allow independent monitors to visit the region. Beijing has sought to play down the notion that people in Tibetan areas have complaints about Chinese rule by portraying any protests as being instigated from abroad by the exiled Buddhist spiritual leader the Dalai Lama and his supporters."
