BP battles to contain gushing leaks fouling the Gulf of Mexico

ROBERT, Louisiana- Scientists have found huge plumes of oil lurking under the surface of the water in the Gulf of Mexico, as BP hit a snag in its latest effort to slow down the oil blasting out of a broken undersea pipe.

At least 790,000 liters (210,000 gallons) of oil has gushed into the Gulf of Mexico since an oil rig exploded April 20 and sank two days later. Eleven people were killed in the blast.
