LOUISIANA: BP suspended its attempt to choke off the gusher at the bottom of the Gulf of Mexico on Thursday so crews could monitor their work and bring in more drilling mud, but the company said everything was going as planned and the effort was expected to resume later in the evening.
News that it would be at least 24 more hours before officials know if the procedure called a ``top kill'' will work came as dire new government estimates showed the disaster has easily eclipsed the Exxon Valdez as the biggest oil spill in U.S. history.
The top kill try was the latest in a string of attempts to stop the oil that has been spewing for five weeks, since the Deepwater Horizon rig exploded and sank off the coast of Louisiana. Eleven workers were killed in the accident.
