Royal Dutch Shell has been forced to cut production of some 106,000 barrels of oil per day in southern Nigeria after a pipeline was demolished, a company spokesman told Xinhua on Thursday.
"The pipeline in Bayelsa state was vandalized on Wednesday by unknown persons but it's not an explosion. Some 106,000 barrels of oil were affected," the spokesman said.
Currently the company was making efforts to repair the damaged pipeline, he added.
Also on Wednesday, four foreigners working for Shell were abducted when armed men, riding in three boats, stormed a vessel servicing a Shell-operated oil field offshore Nigeria's southern coast.
The incidents came a week after Shell lifted the suspension of crude oil export from the west African country following a pipeline explosion that had initially cut production by 180,000 barrels per day in December.
