Brazil's preparations for the World Cup and Olympic Games have run into further trouble after the authorities indefinitely closed a Rio de Janeiro stadium because of roof problems, the city's mayor announced.

The Joao Havelange stadium, home to the Botafogo soccer club and due to host the track and field competition during the 2016 Games, will be shut down until the matter is resolved, Mayor Eduardo Paes said.

"The stadium will remain closed indefinitely," he said. "If it takes a year, then it will be closed for a year."
