Shocking News: World Cup Stadium Collapse.

Three people have been killed in a partial collapse at the stadium due to host the World Cup opener in Brazil next year.

Part of the grandstand was destroyed when a metal structure buckled at the top of the Itaquerao Stadium in Sao Paulo.

Local media reported that the accident was caused by a crane collapse.

The collapse could delay the delivery of the stadium in Sao Paulo by FIFA's December deadline. The stadium was almost complete.

The stadium owner, Sport Club Corinthians, has released a statement on the collapse.

"The board of Sport Club Corinthians Paulista hereby deeply regret the accident earlier in Corinthians Arena. No other information at this time."
