1805 Andy, Bangkok, e-mails: "I've lived in Bangkok for over five years and never have I seen the roads so quiet. Looks like everyone is respecting the curfew. Today from my balcony, I watched the skyline of Bangkok burn before my very eyes. The shock still hasn't sunk in yet".
1755 Jesse Lerer in Bangkok, e-mails: "I live in the historic part of Bangkok and you would never know anything was going on if you didn't hear about it on the television. The majority of the city is operating as usual with the exception of tonight's curfew."
tweets: "To the rest of the world, this may just be today's biggest news but to us who live in Bangkok, it's life. It's reality"
1746 Hannah e-mails from Chiang Mai: "For most of the afternoon red-shirts were blockading Narawat Bridge, a major bridge in the city. Tyres and fire trucks were burned there, firecrackers were set off and shots were fired in the air.
"A couple of hours ago heavily armed soldiers showed up at the bridge and I am not sure what has happened since. Some banks on Tapae Road, which is in the heart of the tourist district, were also attacked.
"The military presence in the city has definitely been increased, we saw low flying helicopters over Chiang Mai this afternoon as well as more armed guards on the streets."
1736 Eve Li is a friend of Fabio Polenghi, the Italian photographer who died after being shot in the chest during the clashes. She told the BBC's Europe Today she had spoken to him on Tuesday night: "I was even asking him 'Do you have a helmet? Do you have a bullet-proof vest, or anything?' And he said he has a helmet, yes, but he doesn't have a vest.
"We were joking about this last night. I didn't foresee that it would be the last phone call that we would have"
tweets: "My brother and sister-in-law stand on Ascott balcony in Bangkok. Surreal atmosphere. Deadly silence in normally 24/7 traffic-jammed area."
1732 Central World has become one of the trending terms of Twitter - an indication of the global interest in this event.
1717 Noah Severs, who runs a jewellery factory in Bangkok, told the BBC: "From a business owner's perspective, the situation right now is far more volatile that it was when everyone was centralised, protesting peacefully in the centre of the city.
"Three weeks ago, Bangkok was still not dangerous. But now the government has started to disperse them they have eliminated the peaceful element who are going home, but you still have some 3,000 protesters unaccounted for who are going round Bangkok burning buildings.
"Right now it's anyone's game what's going to happen in Thailand.
1710 The BBC's diplomatic correspondent James Robbins says: "We're looking at a country with extremely polarised politics and a country which hasn't had a long tradition of stable democracy.
"In essence, both the red-shirts and the supporters of the government think they have been denied legitimacy - that the system has been manipulated against them in some way. It is a real crisis in politics in Thailand.
"That explains why this will be a hard road back for the Thai government, even if they've seen of the protest today."
1705Vaitor tweets: "I'm still in red territory, cinema fire nearly erased, Central World still burning, infrequent shots around the temple."
1650 Sean Tipton, from the Association of British Travel Agents, told the BBC tourists staying in Thailand's southern resorts should not be affected by events in Bangkok.
"Where we send our customers to, hundreds of miles south of Bangkok, there haven't been problems. We have many people there having enjoyable times.
"The main issue for us as well is also Bangkok airport itself, which is perfectly safe. So if you're due to travel out you'll be flown into the airport, and then get a flight from there down to your resort, further south, and you won't encounter any problems."
1645 Bangkok resident Ronnie Reid has been
taking photos of the crackdown
in Bangkok today. Having been in the city for 20 years, he said he wanted to "document today to remember it".

1626 Kenneth from Sweden e-mails: "I'm staying at a hotel in Bangkok's Chinatown district. Smoke is currently rising from at least three locations in the city.

"I don't see how the red army members can expect to garner sympathy from the people when they are looting stores and setting fire to buildings."
1523 The BBC's Lucy Williamson in Bangkok says 23 provinces are now covered by the curfew. "There have been reports coming in all day of anger mounting, particularly in the north and east of the country and that's something the government will be keen to quell as soon as possible.
"The protesters weren't a unified group, there were lots of different people drawn from in and around Bangkok and the more rural provinces. The government has managed to disperse this protest but does not now want to see a nationwide rebellion in its wake."
1513 Finance Minister Korn Chatikavanij tells the BBC he "absolutely" blames former Prime Minister Thaksin Shinawatra - who currently lives overseas - for the unrest.
"Leading up to all of this and during the red-shirt protest he has on several occasions telephoned in rallying protesters - promising them the world if they could lead a red-shirt victory that would allow him to return to Thailand. How could I possibly interpret these phone calls? Every Thai has seen it."
1510 Paris-based media rights group Reporters Without Borderssays it is: "dismayed to learn that Italian freelance photographer Fabio Polenghi, 45, was killed during last night's army assault on deposed Prime Minister Thaksin Shinawatra's "Red Shirt" supporters in Bangkok, and offers its condolence's to Polenghi's family".

1448Thailand's Finance Minister Korn Chatikavanij tells BBC World News the curfew was in place to protect citizens: "Once the protest leaders decided to give themselves in, that apparently displeased a number of the hardcore elements within the red-shirts who subsequently went on an arsonist rampage around the city.

1444 Priya64tweets: "Bangkok looks like a DEAD TOWN now. No cars to be seen... everything shut!... So depressing."

1418 Jim, e-mails from Udon Thani in the north-east: "Today I heard a couple of loud bangs and saw a big plume of smoke. It was actually a government building that's been set alight. The government closed mobile communications and electricity for a while. It's kind of worrying. The centre is like a ghost town - shops are closed, there are security forces everywhere."
"The government is trying to say that the protestors are terrorists but it's quite clear when you look at the pictures of those who were shot, most of the protestors are armed only by rocks or slingshots. And out of the 72 protesters that were killed, these include two health workers, one Italian journalist, one woman and one 14-year-old boy. So it's clearly an indiscriminate attack on the protestors."
1400 The Thai government announces it is extending the curfew from Bangkok to 21 provinces, Reuters news agency says.
1357 Mark Mackinnon,East Asia correspondent for Canada's Globe and Mailis inside Wat Patum, the temple where many protesters have taken refuge. He tweets: "At least five wounded around me at makeshift medical centre in park behind Wat Patum temple, one a friend and colleague... gunfire continues."

1246 Patrick Barta, the
Wall Street Journal's
South-East-Asia bureau chief in Bangkok, tells the BBC the authorities will be closely following reports of trouble around the country.
"There are also people outside of Bangkok who're very upset and so what we're going to be watching tonight is whether or not those people come out in large groups or if it turns out that really there are just a handful or a few hundred militants who are hardcore fighters but don't necessarily reflect the bigger population."
1235 Government spokesman Panitan Wattanayagorn has warned the day could be followed by "another night of suffering".

1232 Adam from Bangkok e-mails: "I have just spent an hour cowered in the back of an office on Sukhumvit 83 after four bombs exploded outside. It's a similar scene around the city - it seems that angry Red Shirts are going on a violent looting spree."

Hundreds of people still sheltering inside....At least one person inside temple has bullet wound. No idea what happened. Gunfire escalating."
1217 The BBC's Chris Hogg in Bangkok says: "There are, of course, tourists caught up in this. They're being advised they can travel through the checkpoints as long as they have their passports and tickets.
"But there is obviously a real concern among the authorities that they need to keep a lid on this in the next two hours.
"Whereas a lot of the city is carrying on as normal there are particular difficult problems in different parts of the city and it's going to take several hours for the security forces to get on top of this."
tweets: "Bangkok sky is now black....... So scared."
1158 The BBC's Lucy Williamson in Bangkok says: "As the sun goes down in Bangkok there's an uncertain atmosphere in the city. All day columns of black smoke have risen above the skyline as protestors set fire to buildings, including a luxury shopping complex and the Bangkok stock exchange.

1131 The BBC's Vaudine England in Bangkok says: " The government says its security operation is designed to secure the safety and security of the public and has already succeeded in clearing Lumpini Park.
"Troops have forced their way over several barricades, protesters in other parts of the city are setting off fires by dousing tyres and even cooking gas canisters in petrol.
"The protesters want to depose the government, which they say is illegitimate. The government says it has given every possible warning and opportunity for a peaceful resolution of this conflict but the time for talk is over."
1131Tilly from Dubai e-mails from Bangkok: "It is very bad here. The fringe elements hiding under the guise of 'red-shirts' have spread throughout the city.

1105 The BBC's Chris Hogg in Bangkok says:
"Over the last hour four police trucks have driven past us with prisoners in the back handcuffed - in one of them the prisoners were monks. We've also heard of attacks on journalists throughout the city - some of the redshirts feel in particular the local journalists were biased against them in favour of the government. Journalists have been wearing green armbands to help them get through the checkpoints, but most have now taken them off because of concerns they are being targeted.
"We've had reports of gunfire directed at the police headquarters and other blasts - nobody knows if they are bombs or grenades. It's still a pretty tense picture here in Bangkok."
1103 Ren Roblestweets: "No matter what side of the political spectrum you're on, can we at least agree that violence IS NOT and SHOULD NEVER BE the answer?"
1101 Jeffrey Lane from Melbourne, Australia, e-mails: We live very close to the Ratchaprasong protest site. A few hours ago we decided to leave our apartment but when we reached the main road we realised we were actually between the army and the red shirts. That was a hairy moment. Luckily we made it across the road safely and we later had a police escort out of the troubled area."
1059 Thai government spokesman Panitan Wattanyagorn tells the BBC a political solution proposal is still on the table:
"The prime minister proposed a road-map and hopes that the demonstrators can join him in implementing this road-map. But the first thing we need to do today is security forces will move in and secure more parameters in the area, to make sure that they isolated the elements that are armed and violent."
1055 Jonny Thomson, a British man living in Bangkok, tells the BBC he is in the centre of the violence around the Victory Monument: "Since the red-shirt leader has handed himself in to the authorities, it's pretty much gone crazy in that two of the major shopping centres have been burnt.

1038 The BBC's Vaudine England says the fires at Central World Plaza and at the Thai Stock Exchange are said to be petering out. The main stage area where the protesters were concentrated for six weeks is now mostly clear and people are cleaning up.

1018 The BBC's Chris Hogg in Bangkok says: "The concern is that although transport was provided for a lot of these protesters to be taken out of the area, the reality is that a lot of the other people who were on the streets and opposing the security forces have just melted away - nobody really knows what happened to them.
"This started off as a political protest but certainly by the end of it, it was unclear how many of these people were motivated by the original aims of the red-shirt protesters."
1010 Television footage shows yellow bulldozers clearing away some of the barricades around the red-shirts' camp.

0931 Leaders of anti-government protests in Bangkok have surrendered and told supporters to end their rally.
