Rival Libyan politicians met last week for UN-sponsored political talks in Geneva aimed at ending the latest round of fighting over the capital, Tripoli, but no tangible progress was scored.

Since April, Tripoli has been under an assault by forces loyal to renegade commander Khalifa Haftar, who is aligned with the rival administration based in the country’s east and backed by the United Arab Emirates, Egypt, and Russia.
Last month, militants and activists loyal to the Libyan warlord Haftar blocked oil exports from the country’s key ports, despite a temporary truce between Haftar’s forces and the rival GNA.
