Hicham Chaib, 31, who goes by the nom de guerre Abu Haniefa, joined the terror group in March 2013 and has risen up the ranks to become one the terror group's most senior executioners.

Based in ISIS' de facto capital Raqqa, Chahib 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 Islamist group that was branded a terror organisation by a judge who found 45 members guilty of terror-related offences in 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 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, it is no stretch to say he is largely responsible for the fact Belgium has seen more nationals join ISIS' ranks than any other Western country.
