Every year, supporters of the Anonymous hacking collective don Guy Fawkes masks and protest capitalism and the political establishment in cities across the world.

Thousands of supporters of the hacker group Anonymous wore Guy Fawkes masks and gathered in Trafalgar Square to protest capitalism and promote civil liberties.

Protesters wearing Guy Fawkes masks lit up Trafalgar Square in London with flares as part of the annual anti-capitalist Million Mask March.
