Jihadi John’s assassination was ‘symbolic’ and ‘personal’ spy chiefs reveal

The assassination of Jihadhi John was a “personal” not a strategic goal, spy chiefs have admitted as they detailed the painstaking methods used to catch him.

Robert Hannigan, a former director of GCHQ, revealed that vein-recognition technology and voice analysis led the security services to identify Mohammed Emwazi “within hours” of a video depicting his masked face and crucially, his hands, emerging on social media.

“We had a race to find out who he was — his size, his hands, but, above all, his voice, made identifying him quite easy,” he said.
