Two workers were killed after part of the Stadium that will host the 2014 World Cup opener in Brazil collapsed. This therefore raises urgent concerns whether the country will be ready for the global event.
The accident occurred in Sao Paulo when a construction crane crashed into a 500 - ton metal structure that in turn cut through the outer walls of the venue, destroying rows of seats and slamming into a massive LED panel that runs across the Stadium's facade.
The Stadium which will host the opening ceremony next year was practically finished before the incident on Wednesday.
Officials said there were no major structural damages to the Stadium but declined to say how much the accident may affect the delivery.
Rodrigo Vessoni a reporter with Sports daily was at the scene, he said "The sound was as loud as a thunderclap or a huge explosion. I had just walked out of the stadium after interviewing Sanchez''.
''There was a lot of running around, a lot of shouting. It was frightening,chills ran through my entire body,it was unbelievable. The noise was metal grating on metal, it was a terrible thing to see".
Soccer governing body FIFA has set a December deadline for all 12 World Cup venues to be ready. The World Cup begins on June 12 with Brazil playing at the Sao Paulo Stadium.
