An air strike has killed five doctors in a hospital in the southern outskirts of Libya’s capital Tripoli, an official from the UN-backed government says.

A warplane belonging to Khalifa Hafta, the rogue general who commands the Libyan National Army, carried out the attack, the health ministry spokesman added.

Libya has been roiled in conflict since the fall of long-time leader Muammar Gaddafi in 2011.
