Riots reportedly ensue in Washington over Trump inauguration as American president

Chaos has erupted in the streets of Washington as anti-Trump supporters clash with police in protest against the Republican's inaugaration.

Protesters chanting "f*** Trump" blocked an entrance to the inauguration by linking arms to prevent people gaining access.

Cops are reportedly using pepper spray in a bid to 'calm the situation' in a protest that is being described as the angriest and most violent yet.
