A strike that began Tuesday afternoon in one terminal at the Port of Los Angeles spread Wednesday, crippling much of the operations at the nation's largest port complex.

By the end of the day, workers had struck at six of the seven terminals at the Port of Los Angeles and three of six terminals at the Port of Long Beach, officials said.

The International Longshore and Warehouse Union Local 63 Office Clerical Unit, working under terms of a set of contracts that expired in June 2010, began setting up the additional picket lines around midday Wednesday. More at the Press Telegram
