What region of Afghanistan borders Pewar, Pakistan and was home to the Mujahedeen?
Tora Bora Tora Bora (Pashto: توره بوړه‎ , "Black Cave") is a cave complex, part of the Spīn Ghar mountain range of eastern Afghanistan. It is situated in the Pachir Aw Agam District of Nangarhar, approximately 50 km west of the Khyber Pass and 10 km north of the border of the Federally Administered Tribal Areas in Pakistan. Tora Bora was known to be a stronghold location of the Taliban, used by military forces against the Soviet Union during the 1980s. Tora Bora and the surrounding Spīn Ghar range had natural caverns formed by streams eating into the limestone, that had later been expanded into a CIA-financed complex built for the Mujahedeen.
South Waziristan South Waziristan (Pashto: سويلي وزيرستان قبايلي سيمه‎ ; Urdu: جنوبی وزیرستان ایجنسی‎ ) is the southern part of Waziristan, a mountainous region of northwest Pakistan, that covers some 11,585 km² (4,473 mi²). Waziristan comprises the area west and southwest of Peshawar between the Tochi River to the north and the Gomal River to the south, forming part of Pakistan's Federally Administered Tribal Areas (FATA). The Khyber-Pakhtunkhwa lies immediately to the east. The region was an independent tribal territory from 1893, remaining outside of British-ruled empire and Afghanistan. Tribal raiding into British-ruled territory was a constant problem for the British, requiring frequent punitive expeditions between 1860 and 1945. Troops of the British Raj coined a name for this region "Hell's Door Knocker" in recognition of the fearsome reputation of the local fighters and inhospitable terrain. The region became part of Pakistan in 1947.
