Oil rig blaze off Louisiana leaves at least 11 missing

US Coast Guard is searching the Gulf of Mexico for at least 11 oil workers missing after an explosion and fire on an off-shore drilling platform.

A boat carrying about 100 survivors has docked in Louisiana.

The Deepwater Horizon rig was still burning hours after the blast on Tuesday night, 84km (52 miles) south-east of the Louisiana port of Venice.

The rig is reportedly tilting about 70 degrees and threatening to topple over.

Its operators, Transocean, said there had been no signs of trouble before the explosion and crews had been doing routine work.

Greg Panagos, a spokesman for the Switzerland-based contractor, said the rig had been drilling at the time but was not in production.
