About Jihadi John
Jihadi John, also known as Mohammed Emwazi, was a British militant of Kuwaiti origin seen in several videos produced by the Islamist extremist group Islamic State (IS) showing the beheadings of a number of captives in 2014 and 2015. A group of his hostages nicknamed him "John" since he was part of a four-person terrorist cell with English accents whom they called 'The Beatles'; the press later began calling him "Jihadi John". The nickname refers to John Lennon of the Beatles; the three other group members were each given the first name of one of the other Beatles. She was the lead reporter of a story, published in The Washington Post, that first revealed his true identity. In January 2015, a threat was issued that they would be killed unless the Japanese government paid a ransom of US$200 million. On 20 September 2014, the United States Senate approved a US$10 million reward for information that led to the capture of anyone involved in the murders of James Foley, Steven Sotloff and David Cawthorne Haines.
