Juan de Nova Island is a territory of Madagascar
Juan de Nova Island (French: Île Juan de Nova, pronounced [il ʒɥɑ̃ də nɔva]), Malagasy: Nosy Kely)[1] is a French-controlled tropical island in the narrowest part of the Mozambique Channel, about one-third of the way between Madagascar and Mozambique. It is a low, flat island, 4.8 square kilometres (1.9 sq mi) in size. [...] Juan de Nova[3] is located in the Mozambique Canal, closer to the Madagascar side: 140 kilometres (87 mi) from Tambohorano, 207 kilometres (129 mi) west-southwest from Tanjona Vilanandro and 288 kilometres (179 mi) from the African coast. [...] Juan de Nova Island was assigned a small garrison of 14 soldiers from the 2nd Marine Infantry Parachute Regiment, as well as a gendarme. They settled in housing that formerly hosted SOFIM workers.[8] The troops receive supplies by air every 45 days.
