Just getting back..have we had confrimation that they were suicide bombers, and NOT remotely detonated devices?
Sky News is reporting that the bus was probably blown up by a homicide bomber, but it has not yet been confirmed by Scotland Yard. They are more interested in trying to trace the particles of the explosives used, as if they were not homicide bombers then they are still at large and that is of major concern.

I don't think it's been confirmed definitely.
