GALLIANO, Louisiana (Reuters) - The 11 victims of last month's deadly offshore rig explosion will be honored at a memorial service on Tuesday as BP Plc prepares for a crucial attempt to seal a blown-out well that has spewed oil into the Gulf of Mexico for five weeks.
The U.S. government piled pressure on BP on Monday to clean up the "massive environmental mess" and a top official said fines would be imposed on the energy giant for the spreading oil spill.
