Oil rig blast prompts environmental concerns

NEW ORLEANS — Workers in Louisiana were trying to contain oil spilled from a rig explosion and prevent any threat to the coast's fragile ecosystem, as the search continued Friday for the 11 workers who were still missing.
No more oil appeared to be leaking from the well head on the ocean floor after the drilling rig exploded and sank in the Gulf of Mexico, the Coast Guard said Friday.
The rig burned for nearly two days until it sank Thursday morning. The fire was out, but officials initially feared as much as 1.27 million liters of crude oil a day could be rising from the sea floor nearly 1,524 meters below.
Coast Guard Rear Adm. Mary Landry said crews were closely monitoring the rig for any more crude that might spill out.
