"The surprising accusation is alleged to be a conspiracy to get deadly attacks on US land," said US lawyer John C. Anderson on Thursday in a press release from the US Department of Justice.
The defendants are Jany Leveille, 36, Siraj Ibn Wahhaj, 40, Hujrah Wahhaj, 38, Subhanah Wahhaj, 36 and Lucas Morton, 41, according to the Justice Department. Amy Sirignano, lawyer for the defendants, refused to comment when reached by CNN.
"No comment right now, until we learn more about the new fees. All our customers will request that they are not guilty of arraignment next week," she said in an email.
In the surprising accusation, Leveille, Hujrah Wahhaj, Subhanah Wahhaj and Morton were also accused of kidnapping and conspiracy to commit kidnapping.
Leveille has been accused of being illegal in the US and having firearms and ammunition. The other four were previously accused of helping and supporting Leveille and conspiring with her.
All five defendants are now charged with "conspiracy from October 2017 to August 2018 to provide material support and resources, including currency, education, weapons and personnel who know and intend to use them to prepare and carry out attacks on death officer and employees in the US ", according to the Ministry of Justice.
All the defendants are in custody pending trial, according to the department.
Some of the abuse of child abuse brought by the state was dismissed by a state judge last year because of a procedural error in the prosecution.
