Explosion at Brazil stadium after suspicious package is detected
There is more security concern ahead of the 2016 Rio Olympics following an explosion early Sunday afternoon at the Maracana Stadium, the venue for the opening ceremony.
The explosion was heard after a robot was sent in following the detection of a suspicious package.
Officials say the package was a tool box.
The development coincides with unease in the Australian team following the theft of a laptop and three shirts during a fire evacuation at the athletes' village on Friday.
