The Longshoremen's international union is investigating reports of a wildcat strike at the ports of Seattle and Tacoma.
ILWU spokesman Craig Merrilees says union officials are trying to sort out what is happening at the two Washington ports and were not sure on Thursday morning if the strike is related to union activity in Longview.
Longview police say hundreds of Longshoremen stormed the Port of Longview early Thursday, overpowered and held security guards, damaged railroad cars, and dumped grain that is the center of a labor dispute.
The spokesman at union headquarters in San Francisco says it appears Longshoremen in Seatlte and Tacoma have taken action on their own. Merrilees did not know how many workers are involved and to what extent the apparent wildcat action has spread.
