- In 1966, the UK leased the US the remote, 17-square-mile Indian Ocean island of Diego Garcia.
- Diego Garcia is now one a key US military bases in the region, and is used as a launchpad for Air Force missions in the Middle East.
- Around 5,000 service personnel and contractors are based on Diego Garcia, which has a bowling alley, burger bar and stores.
- The British government evicted thousands of islanders from their homes on Diego Garcia and the surrounding area to make way for the base.
- The UN's top court recently ruled that the British illegally gained possession of the islands in 1965, placing the future status of the base in doubt.
On the remote tropical island of Diego Garcia, in the middle of the Indian Ocean, lies a secretive, strategically vital US military base
The base has served as a launchpad for US military operations in the Middle East, as a refuelling point for Air Force patrols headed to the South China Sea, and was even designated an emergency landing spot for space missions by NASA.
But this distant outpost of American power isn't located on US territory. Instead it occupies what was formerly a part of the British Empire - and its former owners after throwing off their imperial rulers want it back.
But a recent ruling from the UN's highest said that Diego Garcia and the islands around it were illegally taken by Britain, and should be returned. Although the ruling is not binding, it has put the future of the base in doubt.
