WC final security to be Brazil's biggest

More than 25,000 soldiers and police, the biggest security detail in Brazil's history, will be deployed around Rio de Janeiro for the World Cup final between Germany and Argentina at the Maracana.

Jose Mariano Beltrane, security secretary for the state of Rio de Janeiro, said there will be 9300 Brazilian defence forces and at least 10,000 military police.

"This will be the biggest security operation that the city or country has ever seen," Beltrane said Friday.

"We need to ensure that this event goes off like all the other games in the World Cup."

Asked about the large numbers, Beltrane said they were justified and also pointed out the increase in tourists and the presence of heads of state at the final.

"I prefer to have a great number of men rather than to be caught by surprise," he said.

Beltrane gave no figures about levels of policing at previous matches at the Maracana.

Beltrane said policing would be stepped up around the stadium and in the south zone of Rio, which includes the famed Copacabana and Ipanema beach areas.

He also said access to the stadium area would be limited to people with tickets.

About 75,000 are expected to attend the Sunday's (Monday AEST) final.
