Federal prosecutors say a court hearing is needed to discuss dealing with classified information in the case of an Ohio man accused of plotting a U.S. terror attack.

The request involves charges against Abdirahman Sheik Mohamud (ab-dee-RAH'-mahn shayk moh-HAH'-mud). He's accused of receiving terrorism training on weapons, combat and tactics in Syria, then returning to the U.S. with a plan to attack a military base or a prison.

Prosecutors asked for the hearing in a Tuesday court filing. They say they expect issues related to classified information to arise.

The request, normal in cases involving alleged terrorism, was made under the federal Classified Information Procedures Act.

The 23-year-old Mohamud has pleaded not guilty to charges of supporting terrorism, supporting a terrorist group and making a false statement involving international terrorism.
