PBS Frontline: Fighting for bin Laden
First, correspondents Stephen Grey and Martin Smith go inside The Secret War and uncover new details of CIA-funded Afghan militas tasked with guarding the border, gathering intelligence and launching kill raids against the insurgents and their Al Qaeda allies. Based in Afghanistan, their work is focused on Pakistan.
A former commander of one of these teams, the Khost Protection Force (KPF), tells FRONTLINE about how the team crosses the Afghan border into Pakistan's tribal areas. Under the protection of drone aircraft, they fire mortars against Taliban and Al Qaeda targets inside Pakistan.
