Police have moved in on a number of Occupy Oakland demonstrators who began occupying a foreclosed property at 16th and Broadway, and started launching tear gas at them. The police officers, who appear to be from the Alameda County Sheriff's Department, have warned that they will be arresting any demonstrators who remain in the building.

The live-streaming video from globalrevolution at livestream.com is down at present, but there are reports of a fire having broken out in the street.

This appears to be the first incident of police engaging demonstrators. The General Strike and rally in support of it yesterday were almost entirely peaceful, apart from some minor vandalism to a few buildings by people who do not appear to have been connected with Occupy Oakland.

The crowd in attendance was estimated at between 10,000 to 15,000 people, and the Occupy Oakland activists were successful in achieving one of their main goals: that of shutting down the Port of Oakland. Congratulations and many thanks to all who participated in today's rally!
