San Francisco Police say 350 people have been arrested, and many more arrests are expected as anti-war protesters rove throughout the city, shutting down intersections and bringing traffic to a standstill.
Hundreds of people have joined an impromptu march near downtown. Thousands are gathered next to City Hall. Union Square is closed. Police in riot gear have ringed the shopping district to keep protesters out. At the Federal Building, 2 people were arrested for assault on a federal marshal. The protests have been largely peaceful.
Meanwhile, across the Bay in Oakland, BART briefly shut down the Fruitvale station when about 400 to 500 high school students demanded free rides to Berkeley for an anti-war protest. A BART spokesman says the students left the station and began throwing rocks at passing trains.
