On Thursday, millions of masked activists from the Anonymous group, as well sympathizers, are taking to the streets in a global rally against censorship, corruption and war.
In the United Kingdom, thousands of people wearing Guy Fawkes masks have been met in the center of London by fortified policing operation, which included thousands of extra officers to tackle possible violence. Bottles have also been thrown over the police barriers, and fireworks have reportedly been set off by activists.

The Million Mask demonstration is an annual event, which has been held across the globe since 2012.
Last year, at least 10 people were detained during the Million Mask March by police in London for vandalism of public buildings and violence toward police officers.
This year, the Met police have been granted the right to force protesters to remove their masks in locations where they think criminal offenses are likely to happen.
