Iliass Khayari is a 25 year old Muslim born in Brussels. In December 2012, he left for Syria, apparently sent by Jean-Louis Denis. Denis is a notorious recruiter initially siding with Shariah4Belgium, but later also active in the network of Khalid Zerkani, the man who has recruited three of the perpetrators of the Paris and Brussels attacks. Khayari stayed only half a year in Syria. He returned to Belgium in June 2013 after being hit by a bullet, causing him a pneumothorax and a fractured upper arm.
But his stay in Syria was long enough to commit a cruelty there. In a phone call to a friend at home, which was tapped by the police, he told on the 3rd of May 2013 how he had beheaded a man.
