Police and protesters supporting the Occupy Wall Street movement have clashed downtown following a day of peaceful protests throughout Oakland.
The confrontation began after protesters started a large bonfire in the middle of a downtown street. Dozens of police in riot gear moved in on hundreds of protesters as the flames leapt more than 15 feet in the air from several large metal and plastic trash bins that had been pushed together.
Police warned protesters to clear out before firing several rounds of tear gas and "flash bang" grenades to clear the area.
In the aftermath of the police actions, protesters with cloth wrapped around their faces to protect them from the stench of the gas rallied, chanting "Whose streets? Our streets."
