Libya has been in crisis since long-serving ruler Col Muammar Gaddafi was overthrown and killed in 2011.
Since 2014, it has been politically split between the internationally-recognised interim government in Tripoli (in the west), and the administration in Tobruk (in the east) – which doesn’t recognise the Tripoli government.
Derna, a former Islamic State stronghold during the post-Gaddafi civil war, is now mostly controlled by the eastern administration.
Countries that would like to send support are having issues negotiating with the two administrations.
But despite the split, the government in Tripoli has sent a plane with 14 tonnes of medical supplies, body bags and more than 80 doctors and paramedics.
