Several countries now warn their citizens against travelling to Thailand, in the wake of protests there that forced the cancellation of an Asian leaders summit.
Thai Prime Minister Abhisit Vejjajiva declared a state of emergency on Sunday to quell political unrest, which has now spread to the capital, Bangkok. Five surrounding provinces are under a similar decree.
Britain has urged its citizens to review plans to travel there. Thailand has an estimated one million British visitors each year.
Australia advises people to reconsider travelling to Bangkok and surrounding provinces, and warned its citizens already in the area to avoid unnecessary travel.
The New Zealand government has upgraded its travel advisory to Thailand, saying the situation has deteriorated, and people could become caught in protests.
