Belgian police have fired water cannon to disperse a group of protesters who stormed a central square in Brussels on Sunday.

People had gathered at the Place de la Bourse to pay tribute at a makeshift memorial for victims of last Tuesday's deadly attacks.

The group involved in the demonstration actually call themselves Casuals against Terrorism - not Fascists against Terrorism as earlier reported.

The BBC's Anna Holligan and Shaun Ley in Brussels were watching as the scenes unfolded.
