FACTBOX - Travel warnings for Thailand after weekend mayhem

Reuters - Travel Security Services issued advice to its clients on Monday to defer all non-essential travel to Bangkok and nearby areas, as unrest flared in the Thai capital.

Following are the latest travel advisories issued in response to the unrest:

TRAVEL SECURITY SERVICES - The joint venture between Control Risks and International SOS, which provides security advice and support to business travellers, said non-essential travel to Bangkok and other Thai provinces where a state of emergency has been declared should be deferred.

"The worsening situation has prompted a revision to our travel advice," it said in an advisory. On Sunday, the firm had said normal travel to Bangkok could continue.

BRITAIN - The Foreign Office issued new advice for Thailand on Sunday, urging its citizens to review plans to travel to the country which is visited by an estimated one million British holidaymakers each year.

A Foreign Office spokeswoman said no British tourists had so far reported incidents directly affecting them. Around 40,000 British nationals are believed to live in Thailand.

"In view of the deteriorating security situation anyone considering going to Bangkok should urgently review their plans," the Foreign Office said.

"British residents in, and visitors to, Bangkok are advised to avoid any areas where demonstrations are taking place and to stay indoors as far as possible."
