Cairo - The U.S. embassy in Cairo, Egypt issued a security warning about a potential threat posed by a group they referred to as a "terrorist organization." "The Embassy is aware of a potential threat posted on a website by the Hassm Group, a known terrorist organization, suggesting some kind of unspecified action this evening," the embassy said in a security message. "The Embassy has no further information about this potential threat, but is in contact with Egyptian authorities." Hassm is described as "a non-Salafi revolutionary jihadist group" that uses "violent insurgency tactics against Egyptian security forces, which they refer to as occupiers," according to the Terrorism Research & Analysis Consortium (TRAC), a digital database of research and analysis focused on terrorism.
