evidence: Two of the islands—Europa and Juan de Nova—and the Bassas da India atoll lie in the Mozambique Channel west of Madagascar, while a third island, Tromelin, lies about 450 kilometres (280 mi) east of Madagascar and the Glorioso Islands lies about 200 kilometres (120 mi) northwest of Madagascar. Also in the Mozambique Channel is the Banc du Geyser, a mostly submerged reef considered a part of the Glorioso Islands by France and the Comoros. [...] Mauritius, Madagascar, and the Comoros dispute France’s sovereignty over these islands. Mauritius claims Tromelin and states that the island, discovered by France in 1722, was not ceded by the Treaty of Paris in 1814. Madagascar claims sovereignty over the Glorioso Islands (including Banc du Geyser), though the islands were never a part of the Malagasy Protectorate, having been a part of the Colony of Mayotte and dependencies, then a part of the French Comoros that had become a separately administered colony from Madagascar in 1946. The Comoros also claims the Glorioso Islands (including Banc du Geyser), as a part of the disputed French region of Mayotte. Furthermore, Madagascar has also claimed Bassas da India, Europa, and Juan de Nova since 1972, and a 1979 United Nations resolution (without binding force) demanded the cession of these islands to Madagascar. Seychelles claimed a part of the Scattered Islands too before the signing of the France–Seychelles Maritime Boundary Agreement.
