Rescue teams have arrived from Egypt, Tunisia, the UAE, Turkiye and Qatar. But the efforts are hindered by the political fractures in a country of 7 million people, at war on-and-off and with no government holding nationwide reach since a Nato-backed uprising toppled Muammar Gaddafi in 2011. An internationally recognised Government of National Unityis based in Tripoli, in the west. A parallel administration operates in the east, under control of the Libyan National Army of Khalifa Haftar. Derna has been particularly chaotic, run by a succession of armed Islamist groups, before being uneasily brought under Haftar’s control.
