The two, named as 33-year-old Nourredine H. and his brother Hamza H., will appear before a judge on Saturday to determine whether they should be held in custody beyond an initial 24 hours. The federal prosecution office said in a statement that police had carried out seven house searches in the region of Mons and a further house search in Liege.
