The Foreign and Commonwealth Office has advised against all but essential travel for UK visitors to Thailand, after a number of political protests have resulted in violence.
A Foreign Office spokesperson said the situation in Thailand was "volatile", and British nationals should avoid demonstrations and large gatherings.
"This advice reflects the increasing tension in Thailand and our concern that violent incidents of an unpredictable nature are occurring in many parts of Thailand," said the FCO.
"The situation is volatile and we recommend that British nationals in Thailand or planning to travel to the country check the travel advice on the Embassy website regularly for details of further developments."
