San Francisco (KCBS)  -- About twenty people were arrested today in San Francisco as they tried to block a major downtown San Francisco intersection in an anti-war protest.

KCBS reporter Bob Melrose at the scene says the protesters chanted and gave speeches at Market and New Montgomery a location chosen because it's near the offices of U.S. Senator Dianne Feinstein.

Some of the protesters wore prison garb and two stood inside a cage to symbolize alleged prisoner abuse at Guantanamo Bay.

The protest was scheduled to mark the third anniversary of the start of the war in Iraq. 

"We know that the people of this city are against torture and against indefinite detention and that as a democratic society and we need to recognize that freedom and democracy aren't just words. We have to make them reality," said Berkeley resident Kate Raphael, an organizer with Act Against Torture.

The demonstrators arrested were cited and released.

This past weekend saw thousands of people participating in demonstrations in San Francisco and around the world to mark the third anniversary of the invasion of Iraq.
