Protesters clashed with security staff when they tried to enter a museum in Washington on Saturday, prompting one guard to use pepper spray and leading to at least one arrest, a spokeswoman said.
The incident occurred at The Smithsonian’s National Air and Space Museum around 3:15 pm (1915 GMT), after hundreds of activists had marched from Freedom Plaza, near the White House, along the National Mall towards the US Capitol.
