Counter-terrorist police were on Thursday night searching a flat and business address in east London and five private residences in Leeds after three men were arrested in connection with the July 7 2005 London bombings.

Two men, aged 23 and 30, were arrested just before 1pm at Manchester Airport where they were about to board a flight bound for Pakistan, investigators said. A third, aged 26, was arrested at a house in Leeds shortly after 4pm.
