Osama bin Laden is said to have been involved in an unfolding plot to launch attacks on European cities and may have even targeted the U.S., according to radio reports. The al Qaeda leader sent a directive to operatives and partners saying he wanted a Mumbai-style attack on at least three European countries - the UK, Germany and France - National Public Radio said. Citing intelligence officials, it said gunmen had planned to fire on crowds at busy European tourist sites and take over hotels as part of the plot.The U.S. may also have been a target. The unnamed official told the radio station: 'We know that Osama bin Laden issued the directive. 'And if he issued the directive, we just don't believe that the U.S. wouldn't be on his shortlist of strategic targets. It has to be.' Initial intelligence on bin Laden's involvement came from Ahmad Siddiqui, a German national currently held at the U.S.-run Bagram Air Base in Kabul, Afghanistan. Siddiqui is said to have known Mohamed Atta, one of the alleged hijackers in the September 11, 2001, attacks and to have worshipped at the same mosque in Germany.(Daily Mail)
