A minute's silence was held outside the European Parliament in Brussels as a mark of respect for the victims. 300 people gathered in the university town Louvain-la-Neuve following an appeal on facebook. Gatherings are also planned at Nivelles and Charleroi. A silent vigil is being staged by the Brecht strip wall in Antwerp at 7:30 pm tonight. Protesters will be armed with candle and pen.
