Hicham Chaib, responsible for countless beheadings, crucifixions and amputations in Syria, tells the West that ISIS will “kill your people” during a rant over air strikes in the country.
The footage includes graphic images from war-torn Syria as well as news clips from the ISIS terror attacks in Brussels on Tuesday which claimed 31 lives.
At the end of the nine-minute video, the 34-year-old executes a kneeling ISIS prisoner, shooting him in the head.
Chaib, an organizer of the Sharia4Belgium group, warns: “As long as you bombard our Muslims with F-16s, we will kill your people.”
Standing in what is thought to be the streets of the terror group’s self-declared capital, Raqqa, the Belgian adds that the slaughter in Brussels was what the West had “planted with your own hands.”
Chaib, who goes by the nom de guerre Abu Haniefa, said there would be continued terror “at the heart” of Belgium.
The video emerged after ISIS claimed responsibility for a series of deadly blasts in the Belgian capital on Tuesday, first at Brussels Airport and then at a Metro station.
Chaib joined the terror group in March 2013 and has risen up the ranks to become one of the terror group’s most senior executioners.
Based in Raqqa, he has appeared in dozens of sickening propaganda video releases and photographs, which have led to him becoming something of a poster boy for depraved Belgian extremists who follow his every move while he wages jihad.
Before joining ISIS, Chaib worked as a senior figure within Sharia4Belgium – a radical group that was branded a terror organization by a judge who found 45 members guilty of terror-related offences last February.
Heavily-built Chaib is understood to have served as a personal bodyguard for the group’s lead Fouad Belkacem – who was jailed for 12 years following last February’s trial.
Chahib even served as co-leader of Sharia4Belgium when Belkacem was jailed for two years for incitement of hatred towards non-Muslims in Antwerp in June 2012.
The other two men who helped Chaib lead the group, Feisal Yamoun and Noureddine Abouallal, are both understood to have been killed fighting in Syria in recent years.
A year later Chaib and his wife Kaoutar Bioui fled to Syria to join ISIS, which had yet to declare itself a caliphate and was just one of a number of terror groups battling for power and territory.
Having become one of the first Westerners to join ISIS, Chaib positioned himself as a senior propagandist – using his Facebook page to encourage new recruits and starring in a large number of propaganda videos and photographs released by the then rapidly expanding terror group.
With Chaib being arguably the most prominent Belgian figure in ISIS during its rapid expansion last year, there have been suggestions he is largely responsible for the fact Belgium has seen more nationals join ISIS’ ranks than any other Western country, Daily Mail reported.
