Two people have died in an accident at Sao Paulo's stadium, which is due to host the opening ceremony of the 2014 World Cup finals.
A senior local fire official said crews were called to the Arena Corinthians after reports of a collapsed crane. It fell on top of a metal structure, destroying part of a facade.
The arena was due to be completed at the end of next month to meet a FIFA deadline.
Brazil has admitted it is struggling to have all 12 venues ready.
Brazilian police said two people were killed in Wednesday’s accident, after earlier reports quoted fire officials as saying that three had died.
The crane operator was taken to hospital, but was later released.
