VENICE, Louisiana (Reuters) - Oil from a massive spill in the Gulf of Mexico sloshed ashore on a chain of islands off the Louisiana coast on Thursday as the Obama administration accused BP Plc and its partners of making "very major mistakes" in the ill-fated drilling operation.
BP engineers were expected to start lowering a huge metal chamber over the ruptured seabed well, which has been gushing oil at 5,000 barrels (210,000 gallons/795,000 liters) a day since the Deepwater Horizon rig exploded two weeks ago off the Louisiana Coast, killing 11 workers.
