The Department of Foreign Affairs has advised Irish citizens to exercise ‘extreme caution’ if travelling to Thailand.
It says travellers should curtail their movements if necessary and follow local advice as to where to go, amid continuing political unrest in the capital Bangkok.
The department also advised people travelling to the area to keep informed of the situation on the ground via the media and its website.
Thai Prime Minister Abhisit Vejjajiva has said the situation in the capital, Bangkok, is now under control, following a day of violent clashes between the army and anti-government protesters.
Troops have now moved in on Bangkok's Government House, where tens of thousands of red-shirted protesters based their camp.
Local residents also clashed with protesters in some parts of Bangkok and the building housing the Education Ministry was set on fire.
More than 90 people are reported to have been injured in clashes.
Two people are thought to have died in the violence.
Thailand's military has said it will use ‘all possible means’ to restore order as the protests rage despite a state of emergency in the capital Bangkok.
‘The emergency operations command centre will use all possible means to restore order swiftly and reopen traffic so that people can resume their normal lives,’ Supreme Commander Songkitti Jaggabatara said in a television address.
'We will not use force to crack down on our people because we are fully aware that they are all Thais,' he said.
'But we reserve the right to use weapons in self-defence.'
'I hope the situation will be resolved soon in an orderly manner,' he added.
Mr Vejjajiva declared a state of emergency yesterday after red-shirted supporters of former Prime Minister Thaksin Shinawatra forced the cancellation of the Asian summit in the southern beach resort of Pattaya.
Thaksin Shinawatra’s supporters say Abhisit Vejjajiva only became premier last December because of parliamentary defections the army engineered.
They want new elections, which they would be well placed to win.
