The situation surrounding Libya's various government and other factions continues to grow more complicated all the time, with reports over the weekend that Libyan Army forces loyal to Gen. Khalifa Hifter have attacked and captured multiple oil ports formerly controlled by the Petroleum Facilities Guard (PFG) and the UN-backed unity government.
The PFG are designed wholly around protecting oil facilities, but the unity government has recently been using them in US-backed offensive operations. It appears this may be limiting their effectiveness in being able to guard facilities, though Hifter's Army clearly is substantially armed itself. The indications are that the PFG ceded the sites more or less immediately.
This is also likely to raise questions about where US loyalties in the country lie, as the fighting is ultimately between the UN-backed unity government, which the US is supporting in Sirte, and Hifter, who himself is a longstanding CIA asset who is supposed by the UN-backed Tobruk parliament.
