A drone strike has hit Libya's largest oil refinery, the Ras Lanuf complex on the country's Mediterranean coast, Deutsche Welle reported. Details on damage to processing units and any impact on run rates were not immediately available.

The refinery, operated on the Gulf of Sidra between the cities of Ras Lanuf and Brega, sits at the heart of Libya's oil infrastructure. The complex is tied to the adjacent terminal and the Sirte Basin's export pipeline network, which have repeatedly drawn attack during the country's recurring conflicts.

Libya holds Africa's largest proven oil reserves, and its production and refining sector has functioned only intermittently since the 2011 overthrow of Muammar Gaddafi. Rival governments in the east and west have fought for control of oil facilities, and armed groups have targeted export terminals, pipelines, and storage tanks over the past decade.

The strike follows a period of escalating attacks on Libyan energy infrastructure. Earlier incidents damaged storage tanks at the Ras Lanuf and Es Sider terminals in earlier rounds of fighting, knocking crude storage capacity offline for months.

There was no immediate claim of responsibility for the attack, and no confirmation from Libya's National Oil Corporation on force majeure declarations or revised production guidance.

Libya's crude output, which has hovered around 1.2 million b/d in recent months, remains highly sensitive to any disruption at coastal loading and processing facilities. A prolonged outage at Ras Lanuf would remove the country's principal refining capacity and force greater reliance on imported fuel products.

The watch items: any National Oil Corporation statement on damage assessment and restart timing, force majeure declarations on products or crude storage, and the response of armed factions controlling the facilities around the Gulf of Sidra.
