The National Oil Corporation (NOC) in Libya has issued a warning of potential operations halt at the country's largest operating refinery, Zawiya, due to repeated drone attacks. On Monday evening, a drone strike ignited a massive fire at tank number 402-T, owned by the Brega Oil Company, resulting in severe damage and the collapse of the gasoline-filled tank. The incident follows previous drone strikes on a water desalination plant and a naphtha reservoir at the refinery over the weekend. The NOC has declared a "maximum emergency" and called for an investigation into the attacks. There have been no immediate claims of responsibility, and the NOC did not specify potential culprits. In response to the ongoing attacks, the company may declare a state of force majeure and suspend operations at the refinery, which has a daily refining capacity of 120,000 barrels. The Brega Oil Company has urged all parties to cease hostilities near oil facilities and depots, emphasizing their national significance. The attacks underscore the ongoing security challenges in Libya, where rival administrations and armed groups remain influential despite a 2020 ceasefire. The country split in 2014 after the ousting of longtime leader Muammar Gaddafi, and two governments are currently vying for power: the UN-recognized administration in Tripoli and a rival in the east backed by military commander Khalifa Haftar. The Tripoli-based government has held meetings to address these security concerns and emphasize the importance of protecting vital facilities and installations. Meanwhile, a Libyan parliamentary panel has condemned the attack and called for stronger protection of oil installations.
