Oil giant Shell is being sued in London for the second time in five years over spills in the Niger Delta.
Two communities are claiming compensation and want Shell to clean up their land.
Shell said it is at an “early stage” in reviewing the claims and that the case should be heard in Nigeria.
The Ogale community of about 40,000 people in Rivers State, on the coast of Nigeria, who are mainly farmers or fishermen, are some of the claimants.
