Isil tried to recruit for London attack a year ago

Isil was trying to persuade teenage Muslims to carry out an attack on London Bridge via social media a year before the atrocity happened.

A special report by BBC Inside Out London said one of its journalists was encouraged by the terrorist group to target London Bridge, suggesting he could do it alone or in a group.

The same agent also revealed tutorials on the dark web including instructions on how to make a bomb and a detailed description on how to create a fake suicide vest. The BBC said the details bore similarities to the attack on London Bridge on June 3.
