Leaders of the anti-government protests that have paralysed the heart of Bangkok for weeks have surrendered, after troops stormed their barricades.
At least five people have been killed in the gun battles in the Thai capital, and the demonstration leaders said they did not want anyone else to die.
But some of the so-called red-shirt protesters vowed to fight on.
Fires were started across the city, including at the stock exchange, banks, a huge shopping mall and a TV station.
The Thai government imposed a night-time curfew and ordered television channels to broadcast only official-sanctioned programmes.
Pockets of resistance
In the north-east of the country, a town hall in Udon Thani was set on fire and another, at Khon Kaen, was wrecked.
