FILE PHOTO: Photo of fuel tanks at the edge of a miltary airstrip on Diego Garcia, largest island in the Chagos archipelago and site of a major United States military base in the middle of the Indian Ocean leased from Britain in 1966. Exiled inhabitants of Diego Garcia began a challenge July 17 to a British government decision to kick them off the remote island 30 years ago to make way for the U.S. base. Thousands of islanders from the 65-island Chagos archipelago, many of them born in exile in Mauritius, want Britain to return them to their homeland. clh/HO/U.S./File Photo
