ROBERT, Louisiana (Reuters) - BP Plc suffered a setback on Saturday in an attempt to contain oil gushing into the Gulf of Mexico with a huge metal dome when crystallized gas filled the structure, a blow to hopes of a quick, temporary solution to a growing environmental disaster.
Word of the snag came as balls of tar appeared in waters off a popular Alabama island beach in what may be the first evidence of spilled oil washing into a populated area.
