Oil production in Brazil has been disrupted by a strike against a planned auction for rights to explore a huge offshore oilfield near Rio de Janeiro.
Union leaders said 90% of employees of the state oil company, Petrobras, joined the strike on Thursday.
There were demonstrations outside the Petrobras headquarters in Rio de Janeiro, where this footage was filmed, and near government buildings in the capital, Brasilia.
