In Brazil, demonstrators protesting against the spending on the football World Cup have blocked a number of key roads in the city of Sao Paulo. Activists have called a day of protests in 50 cities across Brazil. The scale of the demonstrations is expected to give an indication of the security challenges the government may face during the football tournament, which kicks off on 12th June. The protesters say they want the government to spend billions of dollars on social projects, transport and housing, instead of the World Cup. One of the biggest protests in Sao Paulo took place in the city's Itaquera district near the Arena Corinthians stadium, which will host the tournament's opening match.
