Civil defense and policemen inspect the damage of an accident at the Arena Corinthians, known locally as the Itaquerao, that will host the 2014 World Cup in Sao Paulo, Brazil, Thursday, Nov. 28, 2013. Two workers were killed when a crane crashed into a 500-ton metal structure that toppled over part of the stadium Wednesday, aggravating already urgent worries that Brazil won't be ready for soccer's showcase event next year.
