BANGKOK, THAILAND - APRIL 13: Red shirt anti-government protesters celebrate the first of three days of Songkran New Year festival amid the political turmoil of weeks of protests and more recently, clashes with the Thai military, at Ratchaprasong on April 13, 2010 in Bangkok, Thailand. Thailand's foreign minister Kasit Piromya ruled out any immediate role for ousted former Prime Minister Thaksin Shinawatra at a global nuclear summit in Washington last night, with US Secretary of State Hillary Clinton urging Thailand to instead embrace reconciliation.
