Yesterday, several hundred indignados, culture jammers and occupiers from across Europe swarmed the North Atlantic Treaty Organization (NATO) headquarters in Brussels in a bold attempt to shut it down.

Organizers explained that the action was a prelude to #OCCUPYCHICAGO and an early preview of the anarchic swarms that will disrupt May’s NATO summit. “Where peace is at stake, nonviolent intervention is necessary,” a press release said.

According to the AFP, occupiers ran across fields and climbed fences leading to the NATO compound chanting “NATO Game Over” and “We want peace now.” They were blocked by a “large police presence” and 483 nonviolent occupiers were arrested.
