Thousands of Protesters Arrive in Bangkok VOA News 13 March 2010 Thai anti-government demonstrators converge at a check point in Wang Noi, Thailand, 13 Mar 2010 Photo: AP Thai anti-government demonstrators converge at a check point in Wang Noi, Thailand, 13 Mar 2010 Thousands of protesters from rural northern Thailand have begun arriving in Bangkok for a rally aimed at toppling the government of Thai Prime Minister Abhisit Vejjajhiva. Trucks and other vehicles filled highways into the capital city Saturday as security forces searched them, ahead of a protest scheduled for Sunday to restore ousted Prime Minister Thaksin Shinawatra to power. Protest organizers say between 600,000 and 700,000 supporters of the United Front for Democracy Against Dictatorship (UDD) will march in Bangkok. About 50,000 police, military and other security forces were patrolling Bangkok. The government has enacted an internal security law that allows the military to impose curfews and restrict freedom of movement. Protest organizers say the rally will be peaceful. The demonstrators, distinguished by their red shirts, are seeking to force Mr. Abhisit to resign from power and call new elections. A military coup ousted Mr. Thaksin from office in 2006. The last time his supporters protested, in April 2009, riots resulted and two people died. Most of Mr. Thaksin's supporters in the UDD are rural and poor, while Mr. Abhisit is backed by members of Thailand's elite known as the "Yellow Shirts." Mr. Thaksin currently lives in Dubai, avoiding a 2-year jail sentence on corruption charges. The French news agency says he has been encouraging his supporters via text messages and his Twitter page.
