‘Jihadi John’ From ISIS Execution Videos Was Under Watch by British Intelligence

LONDON — Mohammed Emwazi was 6 when his parents moved to West London from his birthplace in Kuwait, and he seems to have lived a normal life, studying hard and graduating in computer sciences from the University of Westminster in 2009.

But he came to the attention of the British intelligence services in May that same year, detained as he landed in Tanzania with two friends on what he described as a celebratory safari. British officials thought he and his friends were headed to Somalia, to fight with the Shabab terrorist group and allegedly tried to recruit him as an informant before shipping him back home.

Mr. Emwazi was identified on Thursday as the masked Islamic State fighter called “Jihadi John,” and his journey from computer student to a murderous spokesman for the Islamic State is only beginning to come clear. How and when he was radicalized, and whether the British intelligence services were at fault — either dealing with him too harshly or not identifying him as a serious threat soon enough — are already the subjects of hot debate.
