Chagossian families celebrate at the Groupe Refugies Chagos headquarters on February 25, 2019 the news that the United Nations' top court had told Britain to give up control of the Indian Ocean archipelago. - The UN's International Court of Justice in The Hague said in a legal opinion on February 25 that Britain had illegally split the islands from Mauritius before independence in 1968, after which the entire population of islanders was evicted. It is a major development in a decades-old row with Mauritius over an archipelago that is now home to a huge US airbase. The court's opinion is non-binding but carries heavy symbolic and political weight. (Photo by STRINGER / AFP)
