Anti-government "red shirt" protesters face Thai security forces during clashes in central Bangkok April 10, 2010. Thai troops fired rubber bullets at opposition "red shirts" on Saturday as they moved in to clear a protest site in Bangkok in the biggest confrontation in the month-long campaign for new elections, witnesses said. The red shirts took their protest to the northern city of Chiang Mai, where hundreds forced their way into the governor's office compound in protest at the crackdown in Bangkok.
