The FBI found explosive materials in a Pennsylvania storage unit after two men were charged with bringing homemade bombs to a protest outside the home of New York City’s mayor. The police department in Middletown Township, Pennsylvania, said Tuesday that the FBI conducted controlled detonations after finding the materials at a Public Storage facility in Langhorne. Eighteen-year-old Emir Balat and nineteen-year-old Ibrahim Kayumi were arrested Saturday near Gracie Mansion in Manhattan. According to investigators, they said they were inspired by the Islamic State group. Balat and Kayumi remain jailed after an initial court appearance on Monday. They were not required to enter a plea.
