Protesters and police engaged in a tense and prolonged stand-off outside London's Buckingham Palace as metal barriers cordoning off the area were removed and protesters incited police to fight.

police yelled. protesters shouted at police.

Jostling with the metal barriers segregating police from protesters took place, with some being lifted off the floor and hurled at the law enforcement officials.

As they were felled, some of the protesters sat down in front of the policemen, seeming to act as a replacement barrier of sorts from more violent demonstrators while still retaining masks.
