In Brazil, a public transport strike has caused traffic chaos in the largest city, Sao Paulo, a week before it hosts the opening match of the World Cup. Half of all underground stations were closed as transport workers walked out, demanding a 10 percent pay rise. Angry commuters stormed the Itaquera station, near the stadium where Brazil will play Croatia on 12th June. Police and other public sector workers say they will also strike in the next few weeks if their demands are not met. This is the latest setback in Brazil's preparations for the World Cup, which have been criticised by the tournament's global organisers. But FIFA President Sepp Blatter has called on the Brazilian people to do all they can to support the World Cup.
