Thai Troops Move Into Bangkok Business District VOA News 18 April 2010 Photo: ASSOCIATED PRESS Thai soldiers stand outside a go-go bar on Patpong Road Monday, April 19, 2010, in the business district of downtown Bangkok, Thailand. Thai troops armed with assault rifles have moved to block Bangkok's prime business district not far from thousands of anti-government protesters. Armed Thai troops have moved into Bangkok's central business district to keep anti-government protesters from holding a planned rally. The security forces moved into place early Monday, after the government declared the area, including the Silom Road thoroughfare, off-limits to the demonstrators. Army spokesman Sansern Kaewkamnerd said checkpoints had been set up across the capital in an effort to prevent more of the protesters, known as Red Shirts, from reaching a mass rally site where thousands have gathered since last week. The Red Shirts say they plan another massive demonstration on Tuesday. Also Sunday, a spokesman for the pro-government Yellow Shirts said the group will take action unless the government ends the Red Shirts' protest within seven days. Â The Red Shirts, supporters of exiled Prime Minister Thaksin Shinawatra, have shut down much of central Bangkok since last week. They are demanding new elections, claiming Prime Minister Abhisit Vejjajiva was installed illegally. In 2008, the Yellow Shirts held a weeklong blockade of Bangkok's two main airports to protest the Thaksin government. The Yellow Shirts accuse Mr. Thaksin of corruption and disrespecting Thailand's widely beloved monarchy. Â Some information for this report provided by Reuters and AP. .
