US defence secretary Donald Rumsfeld on Monday said that US forces have bombed some sites in Afghanistan that were believed to have been involved in manufacture of chemical and biological weapons.
Both Rumsfeld and secretary of state Colin Powell have taken serious note of terrorist mastermind Osma bin Laden's claim of possessing chemical or biological weapons, even as other US officials and Pakistani President Pervez Musharraf have expressed doubts over his claim of being in possession of nuclear weapons.
