SAO PAULO, Brazil – Brazil's defense minister says the government may build a fourth airport in South America's largest city and says it would be privately run.

Defense Minister Nelson Jobim also says the government may privatize the operations of the international airport in Rio de Janeiro and another in the city of Campinas.

There was no word on where the new airport in Sao Paulo would be built.

Jobim told reporters Friday that the moves are part of a plan to streamline Brazil's air system, which suffer from chronic congestion and delays. The nation also has been an increase in deadly accidents in recent years.
