The UN's highest court is due to rule on a disputed area of land surrounding the Preah Vihear temple on the border between Cambodia and Thailand.

The long-standing rift has previously led to clashes between the two nations, who both lay claim to the land.

A 1962 verdict by the International Court of Justice declared the temple to be Cambodian, but did not rule on the area around it.

Cambodia sought a clarification of the ruling in 2011, after fighting erupted. Jonathan Head reports.
