Belgium on Tuesday charged four people with involvement in terrorism after 15 early morning raids in the cities of Ghent, Antwerp and Deinze, the federal prosecutor's office said.
"Those persons have been indicted for participation in the activities of a terrorist group, amongst others its funding," a statement said.
"Some of them are suspected of recruiting people with a view to departing to Syria and joining Islamic State (ISIS) there," it added.
