The Sydney Morning Herald reports:
Police in Burma have fired tear gas at about 1000 protesters led by Buddhist monks as they started a march from Rangoon’s landmark Shwedagon Pagoda today, witnesses said. At least 100 people, including some monks, were thrown into police trucks as police tried to stop them joining in, witnesses said. Earlier, police at the pagoda used batons to beat hundreds of anti-junta protesters gathered there.
