Allegations that the oil multinational Shell aided and abetted the torture and murder of Nigerian activists - including the executed writer Ken Saro-Wiwa - will be tested by a full jury trial in New York, after the oil company's attempts to have the case thrown out were rejected.Shell will also stand accused of orchestrating a series of raids by the Nigerian military on villages in the Ogoni region that left more than 1,000 people dead and 20,000 homeless.
