Libya's National Oil Corporation says an armed group closed a pipeline valve in Al-Rayna, halting oil shipments from the Hamada and Tahara fields to the Zawiya refinery. Technical crews stopped pumping at 12:30 a.m. after pressure built up inside the pipeline, threatening the safety of the line and connected facilities. The corporation warned that a continued shutdown would disrupt about 15,000 barrels of daily refinery supply and called on security authorities to secure the pipeline and reopen the valve.
