Not only Brussels, but Antwerp too, is a significant terrorism hub in Belgium. By January 2016 there were about 440 Belgian jihadists in Syria and Iraq, and most of them were young Muslims from the suburbs of Brussels and Antwerp.
It was in Antwerp in March 2010 that Fouad Belkacem, a Belgian radical Muslim of Moroccan descent, established “Sharia4Belgium.” The group was actively involved in recruiting young Belgian Muslims for the jihad in Syria and Iraq. A Belgian court in Antwerp ruled in February 2015 that “Sharia4Belgium” was a dangerous terrorist organization and that Belkacem and his followers were responsible for sending dozens of young men to Syria. Belkacem, an arrogant and intolerant man, got a 12-years prison sentence.
