At least three people, including one policeman, have been killed in violence that erupted as Thai police began clearing protest sites in the capital, Bangkok.
Police want to retake official sites that have been blocked by demonstrators since late last year, but the protesters are demanding that Prime Minister Yingluck Shinawatra resigns.
