HOUSTON (Reuters) - Tropical storm Alex slowed oil spill clean-up and containment work in the Gulf of Mexico and drove more petroleum into fragile Gulf wetlands and beaches on Thursday, with any permanent fix to BP Plc's ruptured deep-sea well still several weeks away.
More than 10 weeks into the crisis, oil continued spewing into the Gulf, clean-up success remained limited and a proposal by the Obama administration to halt all deep-water drilling for the next six months remained in limbo.
