Nigeria oil spill 'worst in decade'

An oil spill near the coast of Nigeria is likely to be the worst there in a decade, a government official said today, as slicks from the Royal Dutch Shell spill approached the southern shoreline.

The slick from Shell’s Bonga field has affected 115 miles (185 kms) of ocean near Nigeria’s coast, said Peter Idabor, who leads the National Oil Spill Detection and Response Agency.
