Former Pakistani prime minister Nawaz Sharif is arrested upon is arrival at Islamabad's airport September 10, 2007. Sharif was arrested and deported to Saudi Arabia on Monday within hours of arriving home from exile, vowing to end the rule of President Pervez Musharraf. Sharif's return from seven years in exile, most recently in London, was always going to spark a confrontation with General Musharraf, the army chief who ousted Sharif in 1999 and cast him into exile in Saudi Arabia the following year.
