On Saturday, the US Attorney in Alexandria, Virginia, announced that Floke-Eckern had been charged with providing material support to a terrorist organization.
According to an affidavit from FBI Special Agent David Robbins, Floke-Eckern became the commander of an ISIS unit called the Nusseibeh Brigade in the Syrian city of Raqqa in late 2016.
The all-female unit was trained in the use of AK-47 rifles, grenades and explosive belts.
An arrest warrant filed Friday by Assistant United States Attorney Raj Barkh said that Fluke-Eckern had trained children in the use of assault rifles, and that at least one witness saw one of the Fluke-Eckern children (about 5 or 6 years old) carrying an automatic rifle into a home. family in Syria.
Prosecutors believe she moved to Syria around 2012. In early 2016, her husband was killed in the Syrian city of Tal Abyad while trying to carry out a terrorist attack, prosecutors said.
Later that year, prosecutors said she married a Bangladeshi ISIS member who specialized in drones, but he died in late 2016 or early 2017.
Four months after the death of that man, she married again to a prominent leader in ISIS who was responsible for the organization’s defense of the city of Raqqa.
