7 July 2005 London bombings
Charles Clarke, Home Secretary when the attacks happened, described the bombers as "cleanskins" before their role in the attacks. This was a new word: it meant "unknown to the government". On the day of the attacks, all four had went to Luton, Bedfordshire, by automobile. The group then went to London by train. They were recorded on CCTV arriving at King's Cross station at about 8:30am.
