ISIS fighter Abu Shaheed was interviewed by Paris Match in March 2013.
Shaheed told the paper at least 500 French Islamists were fighting for ISIS.
Al Monitor reported: A French jihadist interviewed by the weekly Paris-Match in March, claimed that there are “at least” 500 recruits from France alone fighting with ISIS, which is merely one of the jihadist factions in Syria. It has lately been involved in an internecine conflict with other such factions, including Jabhat al-Nusra, al-Qaeda’s official affiliate in Syria.
In November 2013 several French fighters with ISIS appealed to Muslims to join them in the Caliphate.
The ISIS fighters called for attacks in France.
