British oil giant Shell has been forced to delay shipments of crude oil, extracted from Nigerian oilfields, after an apparent dynamite attack on one of its main pipelines in the country.
Unknown gunmen killed at least eight people.
The company expects to delay deliveries of more than 180,000 barrels per day for up to a week.
After the incident, Shell had to shut down two wells that supply the pipeline in the main Niger Delta oil region.
Pipelines have been attacked in the region a number of times before.
Some residents in the Niger Delta area have long claimed they do not benefit from the oil wealth, leading to the attacks.
In other instances, pipelines have been cut by thieves to siphon off the oil.
Anglo-Dutch Shell has involved "force majeure" to formally delay the shipments of oil.
