An investigation has unearthed evidence of Islamic State (IS) agents trying to recruit terrorists for attacks on central London in 2016.
Undercover reporters posing as UK teenagers contacted IS recruiters who suggested they carry out attacks on Westminster and London Bridge.
A counter terrorism expert described the messages as «highly significant».
Inside Out London passed the information to the security services as it was received. Reporters were in contact with people verified by the security services as senior IS recruiters for more than two years.
They posed as fictional characters committed to jihad.
Last July, they discovered the terrorist group was touting on social media for British Muslims to carry out attacks at specific London locations.
