SEATTLE (AP) -- Police used "flash bang" percussion grenades to disperse protesters who blocked an entrance to a Port of Seattle facility.
Occupy Seattle protesters had started setting up wooden crates and aluminum in front of the entrance to Terminal 5 when police moved in to clear the area. Earlier, police reported "multiple" arrests at nearby Terminal 18 after about 100 occupy protesters stopped traffic for about 20 minutes.
The protests were part of a national effort to disrupt West Coast port traffic. The Seattle activity snarled nearby traffic during the Monday evening commute and caused several bus routes to be rerouted or delayed.
