Twenty people are now known to have died in clashes in Bangkok as red-shirt protesters vow to carry on their fight to topple the Thai government.
Abandoned armoured personnel carriers litter the streets of the capital in the aftermath of the fighting that has left four soldiers and a Japanese journalist among the dead.
The red-shirts are demanding that Prime Minister Abhisit Vejjajiva dissolve parliament immediately and leave the country.
The worst political violence seen in Thailand for 18 years erupted as security forces attempted, unsuccessfully, to retake an area held by opposition supporters.
Police pumped tear gas and rubber bullets into crowds of protesters who hurled petrol bombs in response. A government spokesman has denied live rounds were fired.
As both sides tend to their wounded the red-shirts are vowing to continue to defy the state of emergency declared by the government.
