Mohammed Hamzah Khan, 19, faces one count of “attempting to provide material support to a foreign terrorist organization,” which carries a maximum penalty of up to 15 years in prison and a $250,000.
No date has yet been set for Khan’s next court appearance, according to the statement from the Justice Department, which added that the investigation is continuing.
The Illinois teenager was arrested October 4 at Chicago’s O’Hare airport with a roundtrip ticket to Istanbul.
Law enforcement agents who searched Khan’s suburban Chicago home said they had found multiple handwritten letters by Khan and others.
The letters expressed support for the IS group and made reference to jihad, authorities said.
The Central Intelligence Agency estimated last year there were around 15,000 foreigners fighting with the Islamic State and other hardcore militant groups.
Experts say most come from Muslim countries, but there are also hundreds from Europe or the United States. -AFP
