Petty Officer John Edwards told CNN that 1,000 barrels of oil - about 168,000 litres - were seeping from at least two places on the floor of the Gulf under the site.

One of the leaks was at the actual well site, while a second leak was from a pipe connected to the well. The Coast Guard has been using robotic cameras to search the area over the past several days, and until Saturday had found no evidence of a leak.
