Clain is a seasoned jihadist, who was found guilty of helping send extremists to fight US forces in Iraq in 2009 before leaving himself to live in Islamic State's self-proclaimed caliphate six years later. In his video after the Paris attacks, Clain can be heard announcing that "eight brothers wearing explosive belts and carrying assault rifles" had conducted a "blessed attack on... Crusader France."
The chilling propaganda recording warned that the Paris 2015 jihadist rampage was just "the beginning of the storm". The IS gunmen slaughtered 129 people in coordinated attacks at restaurants and bars around Paris, the Bataclan concert hall and the national stadium in an atrocity that stunned the world. His brother Jean-Michel, also a jihadist, was wounded in the same raid that killed Fabien in Baghouz, where the last IS fighters are holding out against US-backed Syrian forces, the sources said. There was no immediate confirmation of the report from the French defence or foreign ministries.
