Citizens around the world are joining in on the Million Mask March, which is largely organized by the hacktivist group, Anonymous. Demonstrators, obscuring their faces with Guy Fawkes masks, are protesting against austerity, mass surveillance and oppression. The protests are taking place in 463 places around the world, including over 100 locations in American cities.

Tense standoffs with police and arrests have been reported in major cities like London but most of the protests have been largely peaceful and uneventful. Check out the map of organized protests around the world here.

"Anonymous is a truth movement advocating hacktivism as self-defense for unconstitutional government. It is our aim to shed light on corrupt government in order to set people free from oppression.

Since Anonymous is a movement and not an organization, our leadership is undefined and fluid. We function not by credentials but by the power of idea to resonate with the whole. With no rulers, there are no rules and no specific membership criteria. In fact, you don't even have to be computer savvy or anonymous to be Anonymous.

Now being hailed "The Most Influential Group in the World," Anonymous has caught the passionate attention of millions. With our annual Nov. 5th global event known as Million Mask March (in commemoration of Guy Fawkes Day), we have for the last two consecutive years organized "The Largest World Protest."
