Violent clashes between pro and anti-government supporters in Thailand's capital, Bangkok, left many injured, and at least one dead.
Dozens of people were injured, some of them from with gunshot wounds, during the fighting near the main government complex.
The fighting began after supporters of Prime Minister Samak Sundaravej tried to retake the government compound, seized by the People's Alliance for Democracy.
PAD supporters occupied the prime minister's office last week, vowing not to leave until Mr Samak resigned.
They accuse Mr Samak's cabinet of corruption and of being a puppet of the exiled former Prime Minister, Thaksin Shinawatra.
The government retains strong support among the nation's rural poor, who have vowed to defend Mr Samak.
Mr Samak declared a state of emergency after the clashes, empowering the military to restore order.
