Longshore workers did not unload cargo from the Zim Shanghai docked at the Port of Oakland on Saturday morning because of safety concerns raised by the presence of police and protesters, according to International Longshore and Warehouse Union spokesman Craig Merrilees.

About 200 protesters planned to demonstrate again during the longshore workers' evening shift, Stop Zim Action Committee spokesman Steve Zeltzer said.

The protesters are demonstrating in response to recent Israeli military action in the Gaza Strip.

Last month protesters blocked cargo from unloading off the Zim Piraeus for nearly five days before the ship apparently departed to Los Angeles with a partial load.
