Brazilian police have used tear gas to stop protesters from approaching a football stadium during a Brazil-Uruguay Confederations Cup match.

About 50,000 protesters marched to the stadium in Belo Horizonte.

A small number of them tried to push past police lines. About 20 people were detained. Julia Carneiro reports.
