Located in the Horn of Africa, at the southern entrance to the Red Sea, Djibouti has been an independent state since 27 June 1977, bordered by Eritrea, Ethiopia and Somalia. The country covers 23,200 km², with a population now above one million, two-thirds of whom live in Djibouti City, the capital. French and Arabic are official languages, alongside Afar and Somali, the national languages. A land of volcanic plateaus and extreme aridity, Djibouti holds Lake Assal, the lowest point in Africa (-153 m), and Mount Moussa Ali, its highest peak (2,028 m). Its strategic position on international shipping routes makes it a major commercial and military crossroads.
