A crane has collapsed on a stadium in Brazil, in turn killing three people.

The Corinthians Stadium was meant to host the 2014 World Cup opener in Brazil, however doubts have now been raised as to it's safety. The stadium was 94% complete, however, today's huge setback has raised major concerns for Brazilian authorities.

FIFA general secretary Jerome Valcke added:  'Extremely shocked by the news  from Sao Paulo. Our thoughts are with the  families of the victims of  this accident.

'We are currently awaiting further details  from the authorities, who are investigating this tragic  accident.'

FIFA are preparing an official statement on  the events that occurred at lunchtime in Brazil but they did say: 'The local  authorities will fully investigate the reasons behind such a tragic  accident.'

FIFA president Sepp Blatter tweeted after  hearing the news: 'I'm deeply saddened by the tragic death of workers @Corinthians arena today. Our heartfelt condolences are with the  families.'

FIFA have released an official statement in connection with the tragic incident;

"FIFA and the LOC (local organising committee) have learnt of the death of workers at the Corinthian's Arena site in Sao Paulo with great sadness."

"We wish to send our heartfelt condolences to the family of the workers who tragically died today."

"The safety of workers is the top priority for FIFA, the LOC, the federal government. We know the safety of all workers has always been paramount for all the construction companies contracted to build the 12 FIFA World Cup stadiums."

"The local authorities will fully investigate the reasons behind such a tragic accident."

The stadium was also meant to host another five matches during the World Cup. The deadline for stadiums to be ready are in December, meaning these fatalities caused by poor safety measures are to be investigated. The crane is thought to have dropped onto a part of the stadium.
