Oil spill near Trinidad and Tobago blamed on barge being tugged to Guyana, officials say

Officials in Trinidad and Tobago say a preliminary investigation into a mushrooming oil spill in waters near Trinidad and Tobago has found that an overturned and abandoned barge blamed for the disaster was being tugged to nearby Guyana

SAN JUAN, Puerto Rico -- A preliminary investigation into a mushrooming oil spill in waters near Trinidad and Tobago has found that an overturned and abandoned barge blamed for the disaster was being tugged to nearby Guyana.

Officials in the eastern Caribbean island nation are trying to determine the owner of the vessel after last week's spill coated beaches along Tobago's southern coast and forced at least two schools to close over health concerns. Officials declared a national emergency on Sunday, and have launched a massive cleanup effort.

Trinidad and Tobago Coast Guard, with help from regional agencies and satellite images, determined that the barge and a tug boat were traveling from Panama to the South American nation of Guyana, the National Security Ministry said Wednesday.

Foreign maritime security investigators also are helping with the ongoing probe, officials said.

Officials have said it was not clear if anybody was aboard the barge when it overturned and apparently began to sink off Tobago's coast. They are still searching for the tug boat and its owner.
