 Groups such as the Madrid-based Committee to Support Tibet claim the death toll in Tibet since the 1950 People's Liberation Army invasion of Tibet to be 1,200,000 and have filed official charges of genocide against prominent Chinese leaders and officials.This figure has been disputed by Patrick French, a supporter of the Tibetan cause who was able to view the data and calculations, but rather, concludes a no less devastating death toll of half a million people as a direct result of Chinese policies.According to an ICJ (International Commission of Jurists) report released in 1960, there was no "sufficient proof of the destruction of Tibetans as a race, nation or ethnic group as such by methods that can be regarded as genocide in international law" found in Tibet.
