Anti-government protest leaders have surrendered amid fierce gun battles after the Thai military entered their camp in central Bangkok, ending weeks of protests.
While protesters threw hand grenades and started fires, Thai troops armed with M16 rifles marched through the central business district.
At least five people have been killed in the latest clashes, including an Italian photojournalist who died from a gunshot wound.
While areas previously occupied by demonstrators are now deserted, a few hard-line red-shirt protesters have refused to give up.
A protester cries as demonstration leaders announce the decision to surrender, saying they did not want anyone else to die.
Downtown Bangkok was ablaze with flames as numerous fires were started, including at the country's largest shopping centre, the stock exchange and a TV station.
Hundreds of police and army personnel were required to escort firefighters into the central district in order to tackle the blazes.
Buddhist monks were among large numbers of protesters arrested by army and police forces. Several red-shirt leaders were also apprehended, with some handing themselves over to police.
The crackdown ends more than two months of protests by red-shirt protesters who have been demanding that the government, which they say is "illegitimate", stands down and new elections are held.
As a long and violent day draws to a close in Thailand, the government says army operations will continue through the night, while a curfew has been imposed from 2000 local time to 0600. A local media blackout has also been enforced.
Curfews were also announced in at least 21 of the country's provinces, as rioting spread and government buildings in some north-eastern cities were torched.
