Ogoni widows testify at The Hague over Shell's alleged complicity in killings

Four Nigerian women bring landmark case over state executions of nine activists in a military court

Four Nigerian women at the centre of a long-running legal battle against oil giant Royal Dutch Shell saw their historic case reach the Hague on Tuesday.

The company is accused of complicity in the state execution of nine Ogoni protesters and human right abuses dating back to 1993. The allegations concern the 1990s violent government crackdown in Ogoniland, in the oil-rich Niger delta region, where oil spills inflicted environmental damage on a huge scale.
