A boat loaded with coal, the Irene E.M., sits idle for two days blocking the entrance of Maracaibo Lake and making oil tankers unable to come and go from oil refineries located along the lake's banks in western Venezuela, Tuesday, Dec. 31, 2002. A tug boat that was to guide the coal boat through the channel unexpectedly stopped laboring. On day 30 of the nationwide strike, Venezuela's oil industry remains mostly paralyzed with few signs that government claims of an increase in production, export and refining operations is actually taking place, industry sources say.
