Reports in Brazil claim three people have died after part of the stadium that will host the World Cup opener in Sao Paolo collapsed.

It is believed that a toppled crane is responsible for causing the accident at the Corinthians Arena, which is due to host the first game of the 2014 tournament on 12 June.

Corinthians have released a statement, which says: "The board of Sport Club Corinthians Paulista hereby deeply regret the accident earlier in Corinthians Arena. No other information at this time."

The incident is the latest of several at the proposed stadia for the tournament, and once again throws into doubt Brazil's ability to meet FIFA's completion deadline for stadiums to be ready for next summer's tournament.

Work was temporarily halted at the Arena da Baixada stadium in the city of Curitiba last month after a judge ruled there was a serious risk of accidents to workers carrying out building work on the site.
