Protesters attend a prayer session during a rally at Ratchaprasong Intersection in Bangkok, Thailand, on Saturday, May 19, 2012. The Red Shirt protesters marked the second anniversary of the army's crushing of a two-month-long Red Shirt protest in central Bangkok, the most violent incident in political unrest that has wracked the country since Thaksin Shinawatra was ousted in a 2006 military coup.
