A drone struck an untreated naphtha storage tank at Libya’s Zawiya oil refinery at about 3:45 a.m. local time on August 8, puncturing tank No. 1-7 and causing a limited leak without triggering a fire, explosion, or injuries. NOC Chairman Masoud Suleman said emergency teams contained the spill quickly, while the Zawiya Oil Refining Company said refinery operations were not significantly disrupted. The attack was the second drone incident at the site within a week, after another strike the previous Saturday that also caused no fire. Tank No. 1-7 contained untreated naphtha, a light and highly flammable hydrocarbon fraction produced early in refining. Zawiya has a historical processing capacity of about 120,000 barrels per day and is one of Libya’s more important domestic fuel plants, supplying refined products to the country’s western region. The refinery had already shut down in May after armed clashes nearby, underscoring continuing security risks around Zawiya and Surman during the current wave of western Libya violence. The incident matters beyond the immediate damage because repeated attacks on a refinery of this scale can raise the risk premium on Libyan crude and refined-product flows, even when output is maintained, by increasing perceived threats to future operations, tanker insurance, and forward contracts. Suleman’s public confirmation of the strike and containment effort also reflects the NOC’s stated approach of presenting itself as a neutral technical manager of Libya’s oil sector while trying to reassure international partners and support broader efforts to keep facilities including Ras Lanuf operating.
