Police used tear gas to repel pro-Tibet demonstrators who protested Sunday outside the Chinese Embassy in Paris. One protester managed to climb the front of the embassy building and take down the red Chinese flag that hangs there. The man tried to hang a Tibetan flag in its place, but a police officer prevented him from unfurling it by snapping the flag pole. Police estimated that 550 demonstrators took part in the protest. They made several arrests. France's Foreign Ministry said Sunday it was "very worried" by the events in Tibet. Noting that Beijing would hold the Olympic Games this August, France reminded China of "the importance of respecting human rights."
