Thai anti-government protesters battled Tuesday with riot police trying to clear protest sites in Bangkok, leaving at least three people dead.
Officials say two protesters and one police officer were killed in the fighting near the Government House. Around 60 people were wounded.
Tear gas, gunfire and explosions could be heard during the midday fight. Both sides appeared to be using weapons.
The violence came as police attempted to clear several camps of protesters trying to oust Prime Minister Yingluck Shinawatra.
Elsewhere, protesters gave up without resistance. At the Energy Ministry, about 100 people were detained following a police operation.
Police say the protesters are violating a state of emergency, but have vowed not to use violence in dispersing the protests.
Hours after the clashes, Ms. Yingluck suffered a setback when the National Anti-Corruption Committee announced charges against her.
The committee said the prime minister was aware of corruption within a national rice-buying scheme, but continued the program anyway. It ordered her to face the charges on February 27.
