CG removing oil from Mona freighter
Spokesman Ricardo Castrodad says crews so far have removed more than 1,300 gallons (4,900 litres) of an oil and water mixture.
Commander David Berliner says crews still have a long way to go and that they do not know how much fuel and oil is aboard because they keep discovering new fuel tanks.
Divers on Saturday were still transplanting corals and endangered species that have been affected.
The Honduran-flagged freighter became grounded June 21 near Mona Island. It was carrying 79 Haitian migrants, all of whom have been detained. The crew had told authorities they departed Haiti and were headed to the French Caribbean island of St. Martin.
