Clashes at Brazil teacher protest
Protesters have clashed with the police in Brazil's largest cities, Rio de Janeiro and Sao Paulo, after marches in support of striking teachers, the BBC reported.
Soon after a peaceful march by more than 5,000 people ended in Rio, a much smaller masked group attacked shops, set fire to a police car and threw petrol bombs.
There were also clashes in Sao Paulo, where shops were ransacked.
Police responded with tear and pepper gas and detained dozens of people.
Four officers were injured and seven banks were vandalized during the unrest in Sao Paulo, according to Reuters news agency.
Extra police had been deployed in Rio de Janeiro for the huge protest coinciding with Teacher's Day, on which the country recognises the profession.
Many shops and banks had boarded up their windows after last week's larger protests, which had gathered more than 10,000 supporters.
Police also cordoned off the Rio house of representatives, which was targeted last week.
