Australia issued new travel warnings for Thailand on Wednesday as anti-government protests continue, advising its citizens of demonstrations in the capital Bangkok and to cancel travel to other areas in the south.
"We advise you to exercise a high degree of caution because of the uncertain political situation and high threat of terrorist attack," Australia's Department of Foreign Affairs said.
Protesters stormed Bangkok's main international airport and gunfire broke out on the streets of the Thai capital on Tuesday as a campaign to oust Prime Minister Somchai Wongsawat turned violent.
Two successive Australian warnings ramped up security advice for the southern provinces of Yala, Pattani, Narathiwat and Songkhla, with the foreign ministry pointing to "terrorist attacks and bombings" in the area on an almost daily basis.
Protests in Bangkok had resulted in fatalities, the department said, while demonstrations at Suvarnabhumi International Airport and Don Muang Airport had disrupted flights.
"Several attacks, including with hand grenades and explosive devices resulting in some fatalities and a number of injuries have occurred. Further violence cannot be ruled out," the warnings said.
