The Thai government has rejected calls by opposition protesters known as Red Shirts for U.N.-mediated talks to end four days of deadly battles in the capital, Bangkok.
Government spokesman Panitan Wattanayagorn said Sunday the military will continue an operation to seal-off the protesters' encampment in Bangkok's main commercial district. He also said the government will not let any foreign agency intervene in Thailand's internal affairs.
Gunfire and explosions shook Bangkok's commercial district into the night Sunday as security forces fired at militant protesters armed with stones, gasoline bombs and guns. Other protesters set fire to tires forming a barricade around their protest site.
Thai authorities said the fighting has killed at least 31 civilians and wounded another 230 people since it erupted Thursday. Red Shirt leaders proposed U.N.-mediated talks with the government if it withdraws troops from the area that the protesters have been occupying since mid-March.
