Operations at several Libyan oilfields were suspended after members of the Petroleum Facilities Guard, a security force responsible for protecting the country's oil infrastructure, shut a valve on the main Hamada-Zawiya crude pipeline, Libya's National Oil, or NOC, said on Tuesday.
The NOC said production had halted at the Hamada, Tahara and NC5 fields and warned it could declare force majeure if the valve remained closed or other oilfields faced similar forced shutdowns.
The state-owned corporation condemned the action, saying it undermined Libya's national economy, caused serious harm to field operators and added to challenges facing the country's oil sector.
The PFG, which operates under Libya's defense ministry, is demanding that it be transferred financially and administratively to the NOC, Reuters reported, adding that the guard said it would impose a partial production cut for one week starting Tuesday at several fields, including Wafa, Al-Khamsa and El Feel. It warned that a complete shutdown would follow if its demands were not met.
The NOC called on relevant state authorities to act immediately to resolve the dispute and address its underlying causes.
"Suspending oil field operations and halting production at this critical time, when global crude oil prices are rising, would inflict a severe and lasting blow to the national economy," NOC said.
Oil and oil royalties accounted for about 86% of Libya's government revenue in 2025, according to Central Bank of Libya data.
