‘Top kill’ has failed, BP admits.....

Oil giant BP admitted on Saturday that its fourth attempt to stop the oil leak at the Deepwater Horizon -- known as "top kill" -- has failed. "I don't think the amount of oil coming out has changed," BP's chief operating officer, Doug Suttles, told reporters. "Just by watching it, we don't believe it's changed." According to government estimates, between 18 million and 40 million gallons of oil have poured into the Gulf of Mexico since the rig exploded on April 20, killing 11 workers.Link
