In 1962, the International Court of Justice awarded the 11-century classic Khmer-style Preah Vihear Temple, together with the land it occupies, to Cambodia. The decision has rankled the Thais ever since.
Earlier Tuesday, three Thai protesters trespassed the border to reclaim the temple, but were immediately arrested. Thai troops then came in to fetch them, thus triggering the face off with Cambodian soldiers there. Bilateral military build-up occurred day by day.
The temple straddles the Thai-Cambodian border atop the Dangrek Mountain and was listed as a World Heritage Site on July 7 by the UNESCO's World Heritage Committee.
