A DAESH recruiter tried to persuade an undercover reporter to carry out an attack on London Bridge a year before eight were killed and dozens injured at the landmark, it has been claimed.
BBC Inside Out London said one of its journalists was urged to target the bridge, either alone or in a group.
The jihadist agent also revealed tutorials on the dark web, including on how to make a bomb and how to create a fake suicide vest.
The videos also showed how to attack a victim with a knife to inflict maximum damage. The BBC said the details bore striking similarities to the attack on London Bridge on June 3.
In the report, the undercover journalist used Twitter to make contact with Birmingham-born jihadist and Daesh recruiter Junaid Hussain.
Speaking through an encrypted messaging site, 21-year-old Hussain said he could help train the reporter on how to make bombs from home. When Hussain, from Birmingham, was killed by a drone in Raqqa in 2015 another recruiter made contact and plotted to assassinate a police officer.
The reporter said: ‘The authorities were fully aware of our contact with the terrorist organisation.’ The programme is on BBC One in the London region tonight at 7.30pm.
An Inside Out poll found 90 per cent of 6,546 asked across England believe there will be more terror attacks.
