The British ambassador to the United States said Sunday that investigators were close to identifying the young militant with a British accent who beheaded American journalist James W. Foley on a video released last week by the Islamic State.
The ambassador, Peter Westmacott, said in an interview on CNN that British counterterrorism officers, by their American counterparts, were making progress in using clues in the video to pick the killer out of the hundreds of British Muslims who had joined the Islamic State group.
“I do know from my colleagues at home that we are close,” he said. “But forgive me if I can’t go much further than that at this point.”
Mr. Westmacott said investigators were trying to match the killer’s voice against recordings of known British militants now in Syria and Iraq. “We’re putting out a great deal of resource into identifying this person,” he said. “And there are some very sophisticated technologies, voice identification and so on, which people can use to check who these people are.”
If Mr. Foley’s killer is identified, it might give intelligence officials insight into the Islamic State kidnapping cell still holding another American reporter, Steven J. Sotloff, and other hostages, and could lead to criminal charges.
But with extremists in control of large parts of Syria and Iraq, it would be hard even to locate the suspect and highly risky to try to take him into custody anytime soon. An attempt early this summer by American Delta Force commandos to rescue Mr. Foley and others held in Syria failed because the hostages had been moved.
“If things stay the way they are now, it would be difficult” to kill or capture the suspect, said a senior U.S. law enforcement official, who spoke on the condition of anonymity because of the continuing investigation. The official said that the FBI and CIA, working with their British counterparts, MI-5 and MI-6, had narrowed to “a short list” the suspects in Mr. Foley’s execution.
The five-minute video released by Islamic State, now the focus of intensive forensic analysis by British and American authorities, is narrated in part by the apparent killer, wearing a black hood with eyeholes, who addresses the camera in English before putting a knife in his left hand to Mr. Foley’s throat. He then begins a sawing motion before the video skips ahead to show Mr. Foley’s severed head atop his corpse in the sand, with what appears to be a different knife lying nearby.
From an analysis of the video images, investigators could estimate the man’s height, study details of his eyes and eyebrows, and note his evident left-handedness. His voice likely has been matched against recordings of many of the estimated 500 militant Britons who have joined the Islamic State group, about half of whom are believed to have returned home.
British counterterrorism agencies conduct extensive eavesdropping in the United Kingdom on people suspected of being extremists and have archived recordings of many of them. In addition, some foreigners who have joined Islamic State have left long Web trails that include audio of their voices on YouTube and other sites.
The Foley video, which incorporated footage of President Barack Obama’s announcing American airstrikes on Islamic State and Mr. Foley’s final words to his family, reflect the sophistication of Islamic State’s extensive media efforts, aimed in part at recruiting more fighters from the West, said Rita Katz, director of the SITE Intelligence Group, which monitors extremist communications.
While Mr. Obama said last week that “the entire world is appalled by the brutal murder” of Mr. Foley, the president’s remarks did not take into account many young Muslims who support Islamic State and have been vocal in their praise of Mr. Foley’s death and the video in particular, Ms. Katz said. Some Twitter users posted excited praise for the video, and a few took images from the beheading video to use as their profile pictures on social media sites.
“Did you see what we can do? There is more!!” wrote one Islamic State supporter monitored by SITE. Another wrote, “I was happy to see the beheading of that kaafir.” Kaafir is the Arabic word for unbeliever.
To judge by Twitter and other social media, “British militants have been impressed that this was done by a British guy,” said Raffaello Pantucci, director of international security studies at the Royal United Services Institute and author of a coming book about Muslim extremists in Britain.
Far from sharing the revulsion of most viewers, those who see Islamic State as defending Islam from Western aggression found the video “empowering,” Mr. Pantucci said. “They say, ‘Look at what we can do, and the powerful Americans can’t do a thing about it.’ They feel they’re part of a community that accepts this and thinks it’s a glorious thing to do.”
Other hostages held by Islamic State have said they began calling their British captors by the names of the Beatles, and the killer of Mr. Foley was known as “John,” with others nicknamed “Paul” and “Ringo.” British and American authorities have so far been unwilling to say who they believe the killer to be, perhaps because to name him without being able to capture or kill him would simply add to his luster in the extremist world.
Speculation among terrorism experts and the British news media has focused on a number of militants known to have joined Islamic State, including a 24-year-old London rapper named Abdel-Majed Abdel Bary. Mr. Bary’s father, Adel Abdel Bary, was extradited to the United States from Britain in 2012 after a long legal battle to face terrorism charges in al-Qaida’s bombing of two U.S. embassies in East Africa in 1998.
The younger Mr. Bary had considerable success rapping under the name “L Jinny” or “Lyricist Jinn,” with singles played on BBC Radio and much-watched videos on YouTube. Some of his raps, Mr. Pantucci said, referred to his father’s prosecution. He left his family’s home in London last year to travel to Syria, where he joined Islamic State and frequently posted to Twitter.
This year, Mr. Bary posted on Twitter a photograph of himself holding a severed head with the comment, “Chillin’ with my homie or what’s left of him.” But Mr. Pantucci said that he appeared to have simply picked up and posed with one of severed heads after a mass beheading by Islamic State in the Syrian town of Raqqa and that posing with a severed head is common among Islamic State fighters.syria - england - london - United States - North America - Middle East - Europe - Barack Obama - Western Europe - United Kingdom
