There also are reports that police may have discovered two unexploded bombs as they sifted through the wreckage of the four bombs that did go off. At least several dozen people were killed in the attacks, and hundreds of others were injured while traveling on subways and a double-decker bus. Scotland Yard has denied finding undetonated explosive devices in the wreckage.
The authorities believe that all four bombs were detonated by timing devices.
There was one claim to the bombings from a previously unknown Islamic group, via the internet, that remains unsubstantiated. Two times in the last three years, subway attacks in London have been averted. Abu Musab al Zarqawi’s name is already being mentioned.
Considering the way that the Bush administration has demonized al Zarqawi and elevated him to legendary status, I just knew he would be on someone’s short list.
