Workers on Sao Paulo's subway system have announced they will launch an open-ended strike, the latest to hit Brazil in the run-up to the World Cup, News agency AFP have reported.

Alex Oxlade-Chamberlain's World Cup dreams are in serious doubt after he suffered a knee injury in England's ill-tempered 2-2 draw against Ecuador in Miami.

England manager Roy Hodgson has said that the player will have a scan on the injured knee in the morning.
FIFA has told officials in Curitiba that they have until February 18 to prove they can get their stadium on track for the World Cup or risk exclusion from this summer's tournament in Brazil.
The 43,000-seater Arena da Baixada is so behind schedule that FIFA doesn't know when it might be ready. The organisation's secretary general said he will decide in three weeks whether to drop the city from the World Cup.
"As you can imagine, the current situation of the stadium is not something we really appreciate," Jerome Valcke told reporters on a visit to the ground. "The stadium is not only late, it is very, very late.
"If you don't have a stadium you can't have games," he added, describing it as an "emergency situation".
Football's governing body FIFA has confirmed that goal-line technology will be used at the next World Cup in Brazil.
FIFA has already licensed two systems - Hawkeye and GoalRef - but has invited more providers to submit tenders.
The technology was first used at last year's World Club Cup in Japan, and will be rolled out at the Confederations Cup Brazil in 2013 as well as the World Cup.
In a statement, FIFA said the technology would be installed in all stadia in order to "support the match officials".
