Libya's National Oil Corporation said an armed group closed valve 7 on the pipeline carrying crude from the Sharara field to the port of Zawiya on Monday. The physical intervention sharply reduced output at one of the country's major oilfields, the state company said.
The affected line links production at Sharara with the coastal export infrastructure at Zawiya. Closing a numbered valve on that route interrupted the movement of crude rather than changing a commercial schedule, making restoration dependent on renewed physical access and operation of the pipeline.
NOC described the reduction as sharp but did not publish the volume lost, the field's output immediately before the closure or the remaining rate after the valve was shut. The scale of the disruption therefore cannot be quantified from the company's announcement alone.
The armed group was not identified in the statement, and no motive or demand was disclosed. Without those details, the episode can be established as an unauthorized shutdown affecting production, but not assigned to a named faction or linked to a stated political or financial objective.
The announcement also did not say whether personnel were threatened, equipment was damaged or other parts of the pipeline remained accessible. Those omissions leave the operational condition of the route uncertain beyond the confirmed closure of valve 7 and the resulting fall in Sharara output.
No timetable was provided for reopening the valve or restoring the field's previous production level. NOC also gave no indication that an agreement had been reached with the armed group, so the duration of the reduction and the steps required to reverse it remained unresolved.
The confirmed facts are consequently narrow but significant: an armed actor gained enough control over a critical point in the Sharara-to-Zawiya system to curtail production at a major field. Further assessment depends on NOC reporting access, restoration and measurable output changes after the shutdown.
