Federal agents say they arrested a Detroit-area man before he could fly to the Middle East to fight Syrian rebels.
Twenty-two-year-old Mohammad Hamdan is charged with breaking a law that prohibits support for terrorist organizations. The government says Hassan planned to fight with Hezbollah, a Shiite Muslim group in Lebanon that the U.S. classifies as terrorist.
Hezbollah fighters have been aiding Syrian President Bashar Assad.
Hamdan was arrested Sunday at Detroit Metropolitan Airport. He told the FBI he was traveling for dental work, not war in Syria.
The Dearborn resident appeared in federal court Monday. He was returned to jail to await a March 24 court hearing. Defense attorney Art Weiss says Hamdan is "adamant that he didn't do anything wrong."
The FBI says an informant recorded conversations with Hamdan.
