Protest in Chile and Brazil

Video: Violent clashes as 100,000-student protest turns ugly in Chile

In Chile, thousands of students angered at rising education costs, clashed with police in the capital, who responded with tear gas and water cannons. The students had flooded the streets for a peaceful march, still wearing their uniforms and backpacks, before it then turned violent. At least 40 were arrested. The students oppose the fact they have to pay 75% of the cost of their own educations - one of the highest rates in the world.
