Ken Saro-Wiwa spoke out against the devastation of Niger Delta by oil companies and the corrupt Nigerian government. He was executed on a school day.

Shell has been accused of making false claims about its oil spill cleanup operations in Nigeria and has been urged to help the worst-hit communities.

Niger Delta community members walked out during talks, saying the company’s offer did not equate to the amount of income they lost.

A faulty pipe from an offshore oil field run by Royal Dutch Shell PLC near Nigeria’s coast spewed crude oil into the ocean for as much as 25 hours.
