The U.S. Department of Justice says a federal grand jury has indicted two Egyptian nationals for transporting explosive materials without permits.

The indictment, unsealed Friday, charges Ahmed Abdellatif Sherif Mohamed and Youssef Samir Megahed, both students at the University of South Florida, with transporting explosives without a license.

Mohamed was also charged with distributing information about a building and using an explosive device with intentions of committing a federal crime of violence.

The men were stopped for speeding and arrested August 4 in Goose Creek, South Carolina, near a U.S. Navy base. The Associated Press reports the explosives they were carrying were pipe bombs.
