Thai-Cambodian troops 'must leave Preah Vihear temple'
The UN's highest court has ordered Thailand and Cambodia to withdraw troops from a disputed border region near an ancient temple complex.
Cambodia had asked the International Court of Justice for a ruling after fighting broke out around the Preah Vihear temple earlier this year.
The temple is in Cambodia. Both nations claim some of the surrounding area.
The judgement is part of a long-running case in which the ICJ is attempting to clarify earlier border rulings.
The BBC's Rachel Harvey in Bangkok says Monday's ruling is just the first round in what promises to be a lengthy and complex judicial process.
Cambodia brought the case asking for a clarification on an ICJ decision from 1962 that awarded it the temple, but left other issues vague.
Thailand wants the case dropped, but has said it will respect the court's ruling.
The ICJ rejected Thailand's attempts to have the case thrown out.
- 1962: UN court awards temple to Cambodia; surrounding land remains undesignated
- 2001-2002: Thai troops block access over water row
- Jul 2008: Unesco lists temple World Heritage site; Thai foreign minister quits; both sides move in troops
- Feb 2009: Clashes leave at least eight dead
- Feb-Apr 2011: Skirmishes at Preah Vihear and elsewhere along border force tens of thousands to flee
The court said in a statement that "both parties should immediately withdraw all their military personnel present in the demilitarised zone and refrain from any military presence in that zone".
The court said both sides must allow access to observers from the regional bloc Asean.
Tension had been increasing between Cambodia and Thailand since Unesco awarded Preah Vihear World Heritage status in 2008.
Clashes broke out around the temple in February and 10 people were killed.
In April, another 18 people died in fighting along the border, around another set of temples to the west.
