Rio's Olympic stadium 'closed due to roof problems'

The stadium that was due to host athletics in the 2016 Olympic and Paralympic Games in Rio de Janeiro has been closed indefinitely following problem with its roof.

The safety issue at the Joao Havelange stadium also leaves the city without a major football stadium, since it was standing in for the Maracana stadium that is being renovated for next year's World Cup.

Rio Mayor Eduardo Paes said that structural problems in the roof mean that it poses a potential threat to spectators in windy conditions.

He added that it was "simply not acceptable" for a stadium built just six years ago, and that those responsible would be held to account.
