Protest by striking teachers turns violent in Rio
Masked demonstrators broke storefront windows and hurled petrol bombs in Rio de Janeiro last night after a protest by striking teachers turned violent.
The protest started out peacefully with at least 10,000 demonstrators occupying one of Rio's major downtown boulevards.
Teachers have been on strike for better pay, but protesters were also angry at what they see as excessive use of police force on demonstrating teachers a week ago.
