Louisiana oil spill threatens environment in Gulf of Mexico
The Deepwater Horizon oil platform burned for more than day before it sank into the Gulf of Mexico on 22 April 2010
The United States Coast Guard has warned that an oil spill leaking from a well in the Gulf of Mexico could become one of the worst in US history.
Eleven workers are missing and are presumed to have been killed when the Deepwater Horizon platform exploded and sank off the coast of Louisiana.
Some 1,000 barrels of oil a day are leaking into the sea, according to officials.
They say the oil leak has the potential to damage beaches, barrier islands and wetlands across the coastline.
