NEW ORLEANS (AP) - BP says oil from its broken well has stopped gushing into the Gulf of Mexico for the first time since April.
The announcement Thursday came after company officials said all valves had been shut on a new cap over the busted well in an experiment to stop the spill.
Kent Wells, a BP PLC vice president, said at a news briefing that oil stopped flowing into the water at 2:25 p.m. CDT.
President Barack Obama called the move a "positive sign," but added, "We're still in the testing phase." The president said he would have more to say on the development Friday.
Obama spoke in response to a question outside the White House after delivering a statement on Senate passage of a financial overhaul bill.
It was a long-awaited milestone in one of the nation's worst environmental disasters. While not a permanent solution to plug the busted well, the success in capturing the oil spewing out was welcome news.
The crisis began when BP's deepwater rig exploded, killing 11 workers.
The cap is not a permanent fix. BP is drilling two relief wells so it can pump mud and cement into the leaking well in hopes of plugging it for good.
