A military aircraft from the eastern Libyan forces has attacked a military camp of a force allied to the internationally recognised government near the western town of Zuwara, Reuters reported citing an eastern military source and residents.
According to reports, the air strike is the closest yet to an oil and gas facility located nearby since the beginning of the offensive.
The situation in the region escalated last week, when the Libyan National Army (LNA) headed by Khalifa Haftar began an offensive to oust what he called terrorist forces in the country's capital.
In the wake of the offensive, Italian energy company Eni reportedly decided to withdraw all its Italian national staff from Libya, announcing the evacuation of Italian employees from the Al-Wafa and El Feel oilfields, as well as the capital Tripoli.
The forces loyal to the UN-backed Tripoli-based Government of National Accord (GNA) announced a counteroffensive on 7 April, the so-called Volcano of Rage, to repel the National Army.
Libya has been suffering from unrest since 2011, when its long-time leader Muammar Gaddafi was brought down and killed. Since then the country has been separated between two rival governments, with an elected parliament governing the country's east and the UN- and EU-backed GNA ruling the west from Tripoli.
