The Scattered Islands in the Indian Ocean consist of four small coral islands, an atoll, and a reef in the Indian Ocean, and have constituted the 5th district of the French Southern and Antarctic Lands since February 2007. They have never had a permanent population. Two of the islands—Juan de Nova and Europa—and the Bassas da India atoll lie in the Mozambique Channel west of Madagascar, while a third island, Tromelin, lies about 450 kilometres east of Madagascar and the Glorioso Islands lies about 200 kilometres northwest of Madagascar. Also in the Mozambique Channel is the Banc du Geyser, a reef under French control claimed by Madagascar since 1976. France and the Comoros view the Banc du Geyser as part of the Glorioso Islands.
The islands have been classified as nature reserves. Except for Bassas da India, they all support meteorological stations: those on the Glorioso Islands, Juan de Nova, and Europa Island are automated.
