But it was not until after their beliefs were reinforced, as they mingled with fellow extremists in jail, that they turned their attention to wreaking bloodshed in the UK.

Dubbing themselves as the “Three Musketeers”, they were poised to strike police and military targets in the UK using a pipe bomb and meat cleaver until the security services intervened.
