Khorasan, also known as the Khorasan Group, refers to a group of senior al-Qaeda members who operate in Syria. The group is reported to consist of a small number of fighters who are all on terrorist watchlists, and coordinate with the al-Nusra Front, al-Qaeda's affiliate in Syria. At an intelligence gathering in Washington, D.C. on 18 September 2014, Director of National Intelligence James Clapper stated that "in terms of threat to the homeland, Khorasan may pose as much of a danger as ISIS." The term first appeared in news media in September 2014, although the United States had reportedly been keeping track of the group for two years previously.
Some commentators have alleged that the threat the Khorasan Group represented was exaggerated to generate public support for American intervention in Syria, and some have questioned whether the group even exists as a distinct entity.
