OAKLAND -- Protesters smashed windows and threw paint at Oakland City Hall and at least a half-dozen other buildings, but there were no reports of arrests or injuries after a group of about 200 protesters moved through downtown Oakland on Sunday evening, police said.

The protest was billed on Facebook as an anti-imperialist rally and march, timed to coincide with the 11th anniversary of the start of the U.S. war in Afghanistan.

Protesters gathered around 6 p.m. at Frank Ogawa Plaza for a rally, then left on foot around 7:15 p.m., heading north toward West Grand Avenue before circling back toward City Hall, according to Officer Cynthia Espinoza of the Oakland Police Department. By about 8:15 p.m., the protesters had dispersed, she said.

Glass front doors and windows at City Hall were smashed, along with windows at a nearby Oakland police office used by recruiting and internal affairs departments, according to Oakland police Lt. Robert Chan.

Protesters also broke windows and threw paint at the offices of the Oakland Tribune; at least three bank branches; offices for Kaiser Permanente and AC Transit; and the Oakland Scientific Facility, which houses computers and data storage for Lawrence Berkeley National Laboratory.
