More than 200 people are reported to have been injured in clashes between police and teachers protesting in the Brazilian city of Curitiba.
Police fired rubber bullets and stun grenades at demonstrators in the southern city on Wednesday. Officers said they had been forced to act when a group of protesters tried to break through police lines around the state legislative assembly.
The teachers were protesting against proposed changes to their pension. Curitiba city officials said 213 people had been injured. The emergency services reported that eight were in a serious condition in hospital.
