HOUSTON (Reuters) - An approaching storm in the Gulf of Mexico will delay by two to three days BP Plc's work on a relief well, the final step in permanently killing the source of the world's worst offshore oil spill, the top U.S. spill official said on Tuesday.
BP suspended work on the relief well aiming to bore into its blown-out Macondo well hours before the National Hurricane Center said a tropical depression formed over the Gulf of Mexico.
