The Belgian Justice Department has leads that jihadists from The Hague have plans to attack the office of the European Commission in Brussels.  In August, a man and a woman of Turkish origin were arrested at Brussels airport where they had returned from Turkey.  They had most probably been in Syria.  Apparently the Belgian Justice Department is searching for additional jihadists in the Netherlands.  All of these jihadists are Dutchmen of Turkish descent who are suspected of having connections to jihadist networks.
