All Afridi clans have their own areas in the Tirah Valley, and most of them extend down into the Khyber Pass over which they have always exercised the right of toll. The Malikdin Khel live in the centre of the Tirah and hold Bagh, the traditional meeting place of Afridi jirgas or assemblies. The Aka Khel are scattered in the hills south of Jamrud. All of this area is included in the Khyber Agency. The Adam Khel live in the hills between Peshawar and Kohat. Their preserve is the Kohat Pass in which several of the most important Afridi gun factories are located.
