ABUJA, Nigeria, Dec. 21 (UPI) -- U.S. supermajor Chevron announced it halted oil production in Nigeria after a militant group took responsibility for attacking one of its pipelines.
The Niger Delta Liberation Force claimed during the weekend that it attacked a Chevron oil pipeline in the Niger Delta.
Chevron said it was suspending oil production in the region to minimize environmental damage from the damaged pipeline, Nigerian news agency Vanguard reports.
"The breach is being investigated and we are reviewing our operations," the oil company said in a statement.
Nigerian military officials said they seized rocket launchers and other weapons from the Niger Delta Liberation Force in November raids.
Bandits in the Niger Delta accuse the government of misappropriating oil revenue. The Movement for the Emancipation of the Niger Delta, the main militant group, warned the government in recently that it was preparing for more attacks on the country's oil industry.
Exxon Mobil, which had several workers kidnapped by Nigerian militants in November, said that it was able to restart production after attacks on its infrastructure.
"We have restarted 15,000 barrels per day of condensate from the Oso field," the company said in a statement.
