Thursday's blast happened west of the site of BP's massive spill which followed an explosion on its Deepwater Horizon rig. White House spokesman Robert Gibbs says all 13 people from the burning Mariner Energy oil and gas facility are accounted for. One has been injured and is being evacuated from the area.

Robert Gibbs, White House Press Secretary, said, "I am told this is a production platform about 100 miles off the coast. I am told the depth of water is about 340 feet, so this is not a deepwater facility. As I understand it, the well was not in active production. "
