Thousands of anti-government "red shirt" protesters cheer as their leaders make an announcement at their encampment in Bangkok's main shopping district May 10, 2010. Thai anti-government demonstrators refused on Monday to end a two-month street protest until the government accepted responsibility for a clash with troops in April that killed 25 people and wounded more than 800.
