UN call for $1bn fund to clean up Nigeria oil spills

The United Nations has called for a $1bn (£613m) fund to clean up oil pollution in the Delta region of Nigeria.

It comes as the oil giant Shell has accepted liability for two oil spills in the region - and now faces compensation claims running into hundreds of millions of dollars.

The report by the UN's Environment Programme said contamination levels were far worse than previously thought - and would take 30 years to clean up.

Local people are also blamed for breaking into pipelines to steal oil.
