Coast Guard officials said an oil rig exploded off the coast of Louisiana, US, sending four people to hospitals Friday. Two were believed to be missing.
Petty Officer 3rd Class Jonathan Lally, a spokesman for the Coast Guard, did not immediately have information on the conditions of those taken to hospitals.
The rig, a production platform owned by Black Elk Energy, is about 25 miles southeast of Grand Isle, La.
Lally says two helicopters, an airplane and small boats were sent to the area. He did not know if the fire caused by the explosion had been put out yet.
