The New York Times reports: Mr. Emwazi was called “Jihadi John” by the foreign hostages he guarded, a number of whom he apparently beheaded in widely circulated videos. He was first identified on Thursday by The Washington Post website, and his name was confirmed by a senior British security official. The official said that the British government had identified Mr. Emwazi some time ago but had not disclosed his name for operational reasons. The identification was also confirmed in Washington by a senior United States military intelligence official.

Information is still vague about Mr. Emwazi, with Britain officially refusing to confirm that he is indeed “Jihadi John” because of what are described as continuing operations.

But Mr. Emwazi appears in 2011 court documents, obtained by the BBC, as a member of a network of extremists who funneled funds, equipment and recruits “from the United Kingdom to Somalia to undertake terrorism-related activity.”

Mr. Emwazi is alleged to be part of a group from West and North London, sometimes known as “the North London Boys,” with links to the Somalia-based terrorist group Al Shabab, organized by an individual who had returned to London in February 2007 and whose name was redacted in court documents.

Another person associated with that group was Bilal al-Berjawi, who was born in Lebanon but brought to West London as a baby. He fought in Somalia and rose through the ranks of Al Shabab and Al Qaeda in Africa before being killed in a drone strike in January 2012, according to Raffaello Pantucci, also a fellow at the Royal United Services Institute.

Mr. Berjawi traveled to Kenya in February 2009, telling his family he was heading for a safari; he and a friend were detained in Nairobi and shipped back to London, but made it to Somalia in October that year.

The neighborhood group “is a tight community and it’s very probable that they knew each other and were part of the same crew,” Mr. Pantucci said.

So it is likely that Mr. Emwazi’s own safari a few months later in May, from Britain to Germany to Tanzania, using the name of Muhammad ibn Muazzam, set off alarms with the British security services, and that he had started on the road to radicalism even before his encounter with MI5 in 2009.
