Brazil Senate approves controversial austerity measures
Violent protests erupt over spending freeze that will affect healthcare, education and social programmes.
Brazilians have been on the streets protesting after the Senate approved a 20-year freeze on government spending that a UN official described as a "historic mistake".
The upper house voted 53 to 16 on Tuesday to lock in the spending ceiling.
Centre-right President Michel Temer says tough measures are needed to get Brazil's finances back under control, but his austerity policies have drawn sharp criticism and prompted violent protests.
Opponents say the austerity measures, which will affect spending on health, education and social programmes, are an attack on the poor in a country where wealth distribution is already among the worst in the world.
Police were out in force in the capital, Brasilia, to protect government buildings from demonstrators during the upper house vote.
