Pro-Tibet demonstrators scuffled with police outside the Chinese Embassy in the Australian capital, Canberra, Tuesday, as they marked 50 years since an uprising sent Tibet's spiritual leader, the Dalai Lama, into exile.
Police say four people were arrested after a group of several hundred activists marched from Australia's Parliament House to the embassy in support of Tibetan independence from China.
Tibetan exiles and their supporters are planning protests across Asia, North America and Europe on Tuesday to mark the anniversary of the Tibetan uprising.
U.S. lawmakers are scheduled to vote this week on a nonbinding resolution that calls for a multilateral effort to bring about a peaceful solution to the Tibet issue.
On Capitol Hill Monday, House Speaker Nancy Pelosi told lawmakers gathered for a commemoration of the uprising that the human rights situation in Tibet has deteriorated over the last year.
On Tuesday, China's Foreign Ministry spokesman urged U.S. lawmakers not to pass the bill.
