Kaf Ajnoun mountain is located on border of which two countries?

Kaf Ajnoun or Mountain of Ghosts is the haunted natural rock fortress of Idinen, also known as the legendary Fortress of Ghosts, or the Cave of the Jinn located in the southern region of Libya, about 25 km north of Ghat. It is bordered by Wadi Tanezuft along the east and the Algerian border from the west. The Idinen summit is about 1280 metres high, and is an offshoot of the mountain nearby. The trail from the Algerian border-side, from Meggedet to Ghat, allows an excellent view of this strange mountain.

English jinn, plural jinni; from Latin genius (guardian spirit) evolving into 'genie' - an invisible spirit mentioned in ancient mythologies, believed to inhabit the subterranean earth.

According to the explorer Hugh Clapperton, who visited the area in 1822, some of the inhabitants of the mountain, apparently with red hair, were heard to beat their drums at night and fire their musquets; which some interpret as a reference to colonial men arriving with their guns during the pre-colonial period. Musquet is a variant spelling of "musket", which is a smoothbore shoulder gun used from the late 16th through the 18th century.
