BP works on another attempt to plug oil leak

HAMMOND, La. (AP) - BP's latest attempt to stop the oil rushing into the Gulf of Mexico is to place what amounts to a mile-long catheter into the gusher.

BP PLC technicians have been guiding deep-sea robots to thread the 6-inch tube with a rubber stopper into the 21-inch pipe spewing oil from the ocean floor. As they tried to plug the leak, the company learned that federal regulators approved spraying chemical dispersants beneath the sea. This was a contentious development because it has never been done underwater.

It's been more than three weeks since the oil rig explosion that killed 11 workers and set off the disastrous spill. Officials have been desperate to plug it as at least 210,000 gallons of oil has been leaking into the Gulf each day.
