From today's New York Times:
"... it was 50 years ago on Tuesday that 300,000 Tibetans surrounded the Dalai Lama’s palace in Lhasa, the start of a failed uprising against Chinese rule that resonates to this day."
"The 1959 Tibetan uprising, or 1959 Tibetan Rebellion began on 10 March 1959, when an anti-Chinese and anti-Communist revolt erupted in Lhasa, the capital of Tibet, which had been under the reign of the Communist Party of China since the Invasion of Tibet in 1950."
"The United States funded training and arms for the guerrillas in Tibet and the United States prior to the uprising and for several years following. From 1959 to 1964, Tibetan guerrillas were secretly trained at Camp Hale by the CIA."
"According to the Tibetan Government in Exile and captured Chinese documents an estimated 86,000 Tibetans died in the events surrounding the 1959 uprising."
From Amnesty International:
"10 March 2009 is the 50th anniversary of the failed Tibetan uprising in 1959 which led to the Dalai Lama fleeing to India.
Last year's anniversary saw widespread protests across the region that lead to arbitrary arrests and numerous reports of human rights violations. These violations included prolonged detention and imprisonment, torture and other ill-treatment.
Based on official statistics, the Chinese authorities have released 3,027 of the 4,434 detained in March 2008. Testimonies of those released, tell a story of desperate prison conditions, including beatings, refusal of medical treatment, and inadequate food and drink."
