BANGKOK, Thailand (AP) âÄî Anti-government protesters vowed Wednesday to avenge those killed and injured in clashes with the police. Soldiers maintained an uneasy calm in Bangkok a day after two people died and more than 400 were injured as police attempted to break up protests that degenerated into ThailandâÄôs worst political violence in more than a decade. Hundreds of workers swept the streets Wednesday around Parliament that were littered with burned-out cars and debris from the rioting. While each side accused the other of using excess force, many pointed to the grievous wounds suffered by several demonstrators, including four who lost parts of their legs, as evidence that the police used heavy weapons. Police said they only used tear gas, and said they believed some demonstrators were hurt be explosives they themselves were carrying. Protesters rallied in their stronghold at the compound of the prime ministerâÄôs office, which they have occupied since Aug. 26. âÄúWe will not negotiate with a man who has blood on his hands,âÄù said key protest leader Sondhi Limthongkul to loud applause. âÄúI ask our brothers and sisters to be strong and turn your sorrow into anger so we can have our revenge!âÄù The protesters from the PeopleâÄôs Alliance for Democracy say Prime Minister Somchai Wongsawat is a pawn of ex-Prime Minister Thaksin Shinawatra, who was ousted in 2006 by military leaders who accused him of corruption. He who now lives in exile. Somchai is his brother-in-law. TuesdayâÄôs fighting began when hundreds of police set out to clear away demonstrators who were blockading parliament to keep Somchai from delivering a key policy speech. Running battles between police and protesters that lasted into the night left 423 protesters and 20 police injured, medical authorities said. About five dozen people were hospitalized overnight.
