Tunisia's Interior Ministry says Libya's former prime minister under Muammar Gaddafi has been arrested. Al-Baghdadi al-Mahmoudi was arrested overnight in the southern town of Tameghza, near Tunisia's border with Algeria, according to ministry spokesman Hichem Meddeb. Meddeb said Thursday two others were detained along with al-Mahmoudi after Tunisian officials found none had visas. Gaddafi remains at large, and his whereabouts unknown. His supporters remain well-armed and fighting is still raging on three fronts in Libya.
