Britain's ambassador to the United States said Sunday that his nation's intelligence services were "close" to identifying the ISIS militant who killed journalist James Foley.
"We're not in a position to say exactly who this is," Sir Peter Westmacott said in an interview with Meet the Press. "But there is some very sophisticated voice-recognition technology and other measures that we have got which should allow us to be very clear about who this person is before very long."
Last week ISIS released a video of an enshrouded man — who appeared to speak with a British accent — executing Foley. Britain previously said it appeared the executioner was a British citizen. --Jon Terbush
