Fireworks roared over Rio de Janeiro’s Maracana Stadium where rehearsals were underway on Wednesday (August 03) in a trial run for the Olympic opening ceremony later this week.

The details of the August 5 ceremony are still very much under wraps.

Security has emerged as a big issue at the Games.

A total of 85,000 members of the armed forces, military, civil and federal police were deployed as of Sunday for the Rio 2016 Olympics.
