America's political divisions turned violent on the streets of Washington during US President Donald Trump's inauguration, as black clad anti-establishment activists smashed shop windows and clashed with police while Trump supporters cheered the new president.
Hundreds of people, some wearing masks, marched through downtown streets, using hammers to claw up chunks of pavement to smash the windows of a Bank of America branch and a McDonald's outlet, all symbols of American capitalism.
A group of people dragged rubbish bins into a street a few blocks from the White House and set them ablaze.
The various protest groups scattered around the city chanted anti-Trump slogans and carried signs with slogans including "Trump is not president" and "Make racists afraid again".
Not all the demonstrators were anti-Trump. Members of Bikers for Trump assembled near the start of the route the new president took to the White House, shrugging off Mr Trump’s opponents who briefly engaged them in a shouting match.
Washington's interim police chief, Peter Newsham, told NBC's local affiliate that the violent protests were "mostly under control". He said about 95 people had been arrested.
Police said in a statement they had charged an unspecified number of people with rioting and that two police officers sustained minor injuries from people who were trying to avoid arrest.
The US Secret Service, Washington police and other law enforcement agencies had about 28,000 officers in place to secure the roughly 7.8 sq km of the city.
The Disrupt J20 group on Twitter said its anger was not directed only at Mr Trump, that it would also have demonstrated had Democrat Hillary Clinton won the election last November.
While Washington is the focal point of the protests, anti-Trump activists have planned sympathy rallies around the United States and the world.
Activists in London hung a banner reading "Build bridges not walls" on the city's iconic Tower Bridge today, a reference to Mr Trump's signature campaign promise of building a wall on the US-Mexican border.
About 30 groups obtained permits for protests today and tomorrow, far more than have been seen in other recent presidential inaugurations.
By far the largest protest is expected to be tomorrow's Women's March on Washington, which some 200,000 people from around the country are expected to attend.
