Prosecutors filed papers detailing why they want Khatallah held until his trial. The motion says he poses a substantial danger to the US and that he has significant relationships with active leaders and members of extremist groups in Libya.
The court filing says the militant voiced opposition to the American diplomatic mission in Benghazi. He's charged with taking part in the attack there that killed the US ambassador to Libya, Christopher Stevens, and three other Americans.
He was flown to Washington from a Navy ship- where he was interrogated after US special forces captured him near Benghazi two weeks ago.
Khatallah faces a possible sentence of life in prison- but prosecutors are expected to file additional charges which could carry the death penalty.
