This morning 67 schools in Flanders and Brussels took part. 46 of the 67 schools were in Brussels, 18 in Antwerp, 2 in Ghent (East Flanders) and 1 in West Flanders.
A total of 126 schools have now signed up to participate (albeit not simultaneously) in the protests that are organised by the action group Filter Café Filtré. The Brussels arts centre Kaaitheater has also joined the initiative and offered free coffee to those taking part in the protest on the busy Sainctelettesquare on the capitals inner ring road.
The weekly protests for improved air quality around schools have been held every Friday during term time since 16 March.
