6 August 2016 - Violence erupted at the Rio 2016 Olympics opening ceremony as police broke up protests outside the Maracana Stadium with tear gas.

Thousands of Brazilians marched through the streets of Rio in protest at the Government splurging billions on the Olympics as the poor struggle to afford the basics.

But the march turned ugly as it reached the Maracana Stadium, which is hosting the opening ceremony tonight. Black-clad activists in masks started burning flags, including the Olympic flag.

Heavily-armed riot police moved in and fired tear gas into the crowd – which included children. Eyewitnesses claimed police were beating protestors.
