A new book describes a series of conversations between the mother of an American hostage who was brutally murdered by Islamic State militants in Syria and one of the men who contributed to his death.

An alleged member of an Islamic State hostage-taking cell nicknamed “The Beatles” has been charged with terrorism offenses in Britain on Thursday after being deported from Turkey.

A jury has convicted a British national for his role in an Islamic State group hostage-taking scheme that took roughly two dozen Westerners captive a decade ago.

A hostage who survived more than a year as a captive of the Islamic State is testifying about the beatings and torture inflicted on him by his captors.

A British national has admitted in federal court that he played a leadership role in an Islamic State scheme to torture, hold for ransom and eventually behead American hostages.

One of two British nationals charged with joining with the Islamic State group and conspiring to torture and behead American and European hostages in Syria is scheduled to plead guilty to criminal charges.

El Shafee Elsheikh and Alexanda Kotey are two of four men who were dubbed “the Beatles” by the hostages because of the captors' British accents. The charges are a milestone in a yearslong effort by U.S. authorities to bring to justice members of the group known for beheadings and barbaric treatment of aid workers, journalists and other hostages in Syria. “If you have American blood in your veins or American blood on your hands, you will face American justice,” said Demers, the department's top national security official. The indictment charges the men in connection with the deaths of four American hostages — Foley, journalist Steven Sotloff and aid workers Peter Kassig and Kayla Mueller — as well as European and Japanese nationals who were also held captive. In July 2014, according to the indictment, Elsheikh described to a family member his participation in an IS attack on the Syrian Army.
