The official flag of the Olympics has been raised in the Brazilian city of Rio de Janeiro, the host city of the next Games.

Rio Mayor Eduardo Paes received the flag from London Mayor Boris Johnson during the closing ceremony in London on Sunday.

The BBC's Quentin Sommerville, in Rio, says the flag is flying in an area that was once one of the city's most dangerous favelas.
