A major oil spill in the Niger Delta was far worse than Shell previously admitted, according to an independent assessment obtained by Amnesty International and the Centre for Environment, Human Rights and Development (CEHRD)…The spill in 2008, caused by a fault in a Shell pipeline, resulted in tens of thousands of barrels of oil polluting the land and creek surrounding Bodo, a Niger Delta town…The previously unpublished assessment, carried out by US firm Accufacts Inc. found that between 1,440 and 4,320 barrels of oil were flooding the Bodo area each day following the leak. The Nigerian regulators have confirmed that the spill lasted for 72 days. Shell’s official investigation report claims only 1,640 barrels of oil were spilt in total. But based on the independent assessment the total amount of oil spilt over the 72 day period is between 103,000 barrels and 311,000 barrels.
