ISLAMABAD: Pakistani authorities were on Thursday questioning at least five US nationals with alleged links to Al-Qaeda, arrested on suspicion of plotting a militant strike, police and officials said. The men were detained on Wednesday in the eastern town of Sargodha, at the home of a member of the Jaish-e-Mohammad, one of a number of militant groups active in Pakistan, which is battling a fierce Islamist insurgency. Security officials said the detainees were planning to strike “sensitive installations” in Pakistan and that maps and laptops were found, while FBI personnel had also been given access to the detainees. Muslim leaders in Washington said the five men had been living in northern Virginia until they disappeared last month.
