New charges filed against Egyptian students in US explosives case

Two Egyptian college students already accused of illegally carrying explosive materials now face more charges. The US Attorney's Office in Tampa says a grand jury issued a new indictment Wednesday charging former University of South Florida students Ahmed Abdellatif Sherif Mohamed and Youssef Samir Megahed with an additional charge of possessing a destructive device. Mohamed also faces new charges of providing material support to terrorists and possessing a pistol and a rifle in violation of visa guidelines. The FBI says he made a video demonstrating how to convert a remote-control toy into a detonator for a bomb. The two were arrested after deputies in South Carolina last August discovered what they described as bomb-making materials in their trunk during a traffic stop. Lawyers for the men have said the materials were homemade fireworks.
