A military source reportedly said there was a “high degree of certainty” that Mohammed Emwazi, otherwise known as Islamic State (ISIS/ISIL) militant “Jihadi John,” was killed in a drone strike in the Syrian capital of Raqqa.
According to British Prime Minister David Cameron, the outcome of the Nov. 12 airstrike that targeted Emwazi is not known at the moment — but the attack was “the right thing to do” nonetheless, BBC reports.
Cameron added that the United Kingdom had been working with the U.S. “literally around the clock” to track down Emwazi.
“We are still assessing the results of this strike, but the terrorists associated with Daesh need to know this: Your days are numbered, and you will be defeated,” Secretary of State John Kerry said, using an Arabic acronym for ISIS.
“There is no future, no path forward for Daesh, which does not lead ultimately to its elimination, to its destruction," he added.
On Nov. 13, the Pentagon announced that it was "reasonably certain" that Emwazi died in the aistrike, the New York Times reports. They are, however, still seeking verification of his death.
Emwazi, 27, was part of a group of militants who traveled from London to Muslim countries like Syria to engage in terrorist activities. Emwazi first came to prominence in August 2014, when he appeared in a beheading video released by ISIS.
His identity was revealed in February, as the public learned of his wealthy upbringing in the U.K. and the degree in computer science he received from the University of Westminster.
“If this strike was successful — and we still await confirmation of that — it will be a strike at the heart of ISIL," Cameron said of the airstrike, "and it will demonstrate to those who would do Britain, our people and our allies harm we have a long reach, we have unwavering determination and we never forget about our citizens.”
