Description:Hundreds of striking workers involved in the Panama Canal expansion project gather in the town of Cocoli. Some 6,000 went on strike on Tuesday, demanding increased pay and improved working conditions. A spokeswoman for the Panama Labour Ministry told the striking workers that the construction consortium was in breach of contract by not paying workers. The construction work is expected to be completed by 2014, a century after the canal was opened at a cost of 25,000 lives.(1:17)
