YENAGOA, Nigeria May 28 (Reuters) - Militants attacked the major Nembe pipeline in Nigeria's Delta region, two officials said on Saturday, hours after the Niger Delta Avengers militants claimed a strike on the facility.
Nigeria's oil output has fallen to a 20-year low due to attacks on oil pipelines in the southern swamps, home to much of its oil and gas wealth, which have compounded the impact of low oil prices on Africa's largest economy.
"We heard multiple attacks last night," said Bello Bina, a local official in Bayelsa state, confirming that the Nembe pipeline carrying Bonny Light crude exports had been hit.
Royal Dutch Shell, which exports Bonny Light, was not immediately available for comment. But Nengi James, a chairman of the Nembe Oil and Gas Committee that liaises with oil firms, also said the pipeline had come under attack.
The "Avengers", who have been targeting oil and gas facilities as part of what they say is a battle for the Delta's independence, said on twitter it had attacked the Nembe pipeline at 0215 local time.
"Something Big is about to happen," the group later tweeted.
Shell declared force majeure on Bonny Light loadings after a previous attack on the Nembe creek trunk pipeline, but some exports had been continuing with delays caused by repair work.
