Nigeria: Oil workers threaten to shut down output
Nigeria's main oil workers' union says it is putting platforms on red alert for a possible shutdown of the country's output.
The workers are taking part in growing nationwide protests against the removal of a fuel subsidy.
The government is also coming under pressure from another deepening crisis in the country, that of sectarian violence.
The Islamist sect in Nigeria, Boko Haram, has posted a video online attempting to justify recent attacks on Christians.
