|  | The BIOT Post Office is managed by the
                Foreign and Commonwealth Office of the British Government and
                is operated on its behalf by Sure (Diego Garcia) Limited. The
                Post Office provides outbound postal services from the
            island of Diego Garcia. Incoming mail is handled by both the US Postal
                Service and the British Forces Post Office. British Indian Ocean
            Territory (BIOT) lies about 1770 km east of the Seychelles. The islands have a land area
            of only 60 sq km and 698 km of coastline. Diego Garcia, the largest and most southerly
            island, is 44 sq km. The climate is hot, humid and moderated by trade winds. The terrain
            is flat and low and most areas do not exceed two metres above sea level. The Chagos islands were first discovered, uninhabited, in the
            16th century. The French assumed sovereignty in the late 18th century and began to exploit
            them for copra, originally employing slave labour. Under the treaty of Paris in 1814,
            France ceded to Britain Mauritius and its dependencies, which comprised Seychelles and the
            Chagos Archipelago. The Chagos islands were detached to become part of the British Indian
            Ocean Territory in 1965. Diego Garcia has approx. 3,000 inhabitants, mainly UK and US
            military personnel and civilians, and Filipino and Mauritian civilians. |
