Authorities say part of the stands at the new Palmeiras arena in Sao Paulo has collapsed, killing one worker and injuring another.

Firefighters say the man died when a large concrete column fell on him. The other worker sustained minor injuries.

At least three columns collapsed, and police were investigating the causes of the accident near lunchtime on Monday.

Other workers were in the area but were able to flee.

The Arena Palestra is set to be concluded by the end of the year. It will not host World Cup matches in 2014 but could be used for training.

Sao Paulo is not a host city for June's Confederations Cup.

Palmeiras is the team with most national titles and one of the country's most popular clubs.
