8m litres of oil-water collected
Louisiana - The US Coast Guard says about 7.95 million litres of an oil-water mix has been collected since a spill in the Gulf of Mexico.
BP chief operating officer Doug Suttles has said the mix collected is about 10% oil and the rest water.
The Coast Guard said on Saturday that nearly 190 vessels are involved in the cleanup efforts. More than 257km of boom to contain the oil has been put out and crews have used nearly 1 041 000 litres of chemicals to break up the oil on the water's surface.
More than 4 500 people are responding and another 2 500 volunteers have been trained to help.
An oil rig exploded 80km of the Louisiana coast April 20 and sank two days later. Oil has been spewing at about 757 000 litres a day.
