The pair of ISIS operatives will be coming to the United States within the next few weeks to stand trial over their alleged role in the torture and beheadings of US hostages in Syria. In 2015, a British-Kuwaiti militant dubbed "Jihadi John" - believed to be the executioner in the ISIS videos, was killed in a US drone strike.
Update: WaPo just reported that the two ISIS terrorists were charged in the deaths of US hostages.
Alexanda Kotey and El Shafee Elsheikh are in U.S. military custody in Iraq. They were captured by a Kurdish-led militia in early 2018 but brought to Iraq last October.
The men have been accused of taking part in the kidnappings of international hostages, including journalists James Foley and Steven Sotloff and U.S. aid workers Kayla Mueller and Peter Kassig. Kotey and Elsheikh have admitted their involvement in the kidnapping, sexual assault and death of Mueller in 2015. -Fox News
