Journalists and members of the Louisiana Wildlife Federation stand on a sand bank in Breton Island as oil leaking from the Deepwater Horizon wellhead continues to spread in the Gulf of Mexico, May 3, 2010. Energy giant BP Plc was under siege on Monday over the catastrophic oil spill from its ruptured Gulf of Mexico well, as its shares fell and the U.S. government pressed it to try to limit a major environmental disaster. As a huge oil slick advanced toward the Gulf Coast shoreline, the London-based company came under increasing pressure to do more to stop, or at least control, what is fast turning into the worst oil spillage in U.S. history.
