Federal prosecutors said today the main suspect, identified only as Ismail I, was charged with membership in the Islamic State of Iraq and the Levant, an al-Qaeda breakaway group.
His brother, Ezzeddine I, and German national Mohammad Sobhan A were charged with supporting it. They're also charged with procuring equipment and money.
The main suspect is accused of training and fighting for the group in Syria last year. Prosecutors say the group sent him back to Germany to procure money, medicine and military supplies.
