COVERT video footage of two of the July 7 bombers and a man accused of helping them, walking down a London street with a “committed terrorist”, was shown to a court for the first time.

Bombers Mohammed Siddique Khan, of Thornhill Lees, and Shezhad Tanweer, of Leeds, were filmed with alleged conspirator Waheed Ali.

All were briefly captured on film with a man called Ausman and two others strolling past a kebab shop in the East End over a year before the 2005 attacks.

The never-before-seen surveillance footage, showing the six men in Green Street near Upton Park, was recorded by authorities who were monitoring the activities of Ausman and his associates on March 23, 2004.

Later the same evening a discussion between Khan, Ausman and others, whose voices can’t be recognised, about various ways to defraud banks and credit card companies was secretly bugged, a jury was told.

Ali, 24, from Tower Hamlets, east London, is standing trial with two other men, Mohammed Shakil, 31, and Sadeer Saleem, 27, both from Beeston, Leeds, accused of conspiring with Khan, Tanweer, former Rawthorpe High School pupil Jermaine Lindsay and Hasib Hussain and others unknown to cause explosions between November 17, 2004 and July 8, 2005.

The four suicide bombers murdered 52 people when they set off bombs on the capital’s transport network in 2005. The defendants deny the charge at Kingston Crown Court.

All three are alleged to have carried out a two-day reconnaissance mission in the capital on December 16 and 17, 2004 with bombers Hussain and Lindsay.

They are accused of pinpointing potential targets and the court has heard they visited the Natural History Museum, the London Eye and the London Aquarium.

The court had previously heard that Khan, Tanweer and Ali were viewed on a number of occasions in early 2004 having travelled south from Leeds to visit Ausman.

On March 23 Ausman’s Suzuki Jeep and a Corsa driven by Khan were tracked as they travelled in convoy between Crawley, West Sussex, Slough and various parts of London where they were caught on film.
