Al Qaeda is re-establishing training camps in Pakistan’s tribal areas along the border with Afghanistan and Osama bin Laden and his deputy Ayman al-Zwahiri are probably there too, the new US intelligence chief said on Tuesday. “To the best of our knowledge the senior leadership [of Al Qaeda], number one and number two, are there,” retired admiral Michael McConnell, the new director of national intelligence, told a congressional hearing. He said Qaeda is still the top danger to the US, but Iran is also on the rise and on course to produce nuclear weapons early in the next decade.
