Oil rig explosion leaves 11 missing
The US Coast Guard is searching the Gulf of Mexico for at least 11 oil workers who went missing after an explosion and fire on an off-shore drilling platform.
The Deepwater Horizon rig was still burning hours after the blast on Tuesday night.
Seventeen of the 176 workers were evacuated by air and sea yesterday and another 98 were later rescued by boat.
Operators of the rig, Transocean, says there had been no signs of trouble before the explosion and crews had been doing routine work.
A spokesman for the Switzerland-based contractor, Greg Panagos, says the rig had been drilling at the time but was not in production.
The cause of the blast is still unclear.
