Thai Protesters Send Convoy to Suburban Market VOA News 28 April 2010 'Red Shirt' anti-government protesters, holding portraits of the Thai king and queen, leave their fortified camp in central Bangkok for a rally in the outskirts of the capital, 28 Apr 2010 Photo: AFP 'Red Shirt' anti-government protesters, holding portraits of the Thai king and queen, leave their fortified camp in central Bangkok for a rally in the outskirts of the capital, 28 Apr 2010 Thai troops have fired into the air near a convoy of anti-government protesters in a effort to block their efforts to take their protest to a suburban Bangkok market. Several thousand Red Shirt protesters left their fortified encampment in Bangkok's downtown commercial district in pickup trucks and motorcycles Wednesday to move their seven-week campaign outside the city. The government has vowed to keep the Red Shirts from spreading the protest outside their encampment.  The convoy is traveling on a road where a group of Red Shirts briefly set up a blockade earlier this week to block additional Thai security forces from heading into the city. The anti-government forces have virtually brought Bangkok to a standstill in their drive to force Prime Minister Abhisit Vejjajiva to call new elections. The Red Shirts placed tires along Bangkok's elevated railway system Tuesday, shutting down the system for several hours. The activists said they were worried that Thai troops might use the station to attack them from above. The protests have turned bloody, with at least 26 people killed and nearly 1,000 wounded during clashes with Thai security forces.  The Red Shirts are supporters of former Prime Minister Thaksin Shinawatra, who was ousted in 2006 on allegations of corruption.  They say Mr. Abhisit was installed in office illegally. The Thai government has accused Red Shirt leaders of plotting to overthrow Thailand's revered monarchy, a charge the movement denies. But Mr. Abhisit said earlier this week his government will try to enforce the law with "minimum losses," as he put it. He also promised to try to find a political resolution to the crisis, and he pleaded for "patience and cooperation."
