The U.S. Coast Guard cutter Southern Responder (R) is pictured during cleanup activity in the Gulf of Mexico, south of Louisiana, where oil leaking from the Deepwater Horizon wellhead continues to spread, April 28, 2010. The Coast Guard on Wednesday set a "controlled burn" to battle a giant oil slick from last week's deadly offshore drilling rig explosion, as the spill threatened wide-scale coastal damage for four U.S. Gulf Coast states.
