Charging the 'Beatles': Inside the case against IS militants

FILE - In this March 30, 2018 file photo, Alexanda Amon Kotey, left, and El Shafee Elsheikh, who were allegedly among four British jihadis who made up a brutal Islamic State cell dubbed "The Beatles," sit on a sofa during an interview with The Associated Press at a security center in Kobani, Syria. The Justice Department is preparing to announce charges Wednesday against two men from Britain who joined the Islamic State and were part of a cell that beheaded Western hostages, a law enforcement official said. Their arrival in the U.S. to face charges sets the stage for arguably the most sensational terrorism prosecution since the 2014 case against the suspected ringleader of a deadly attack on the diplomatic compound in Benghazi, Libya.
