At least 22 aid workers have been killed in South Sudan his year alone, according to the UN, who say it tops the list of most dangerous countries for aid workers in the world.
Some 9.4 million people – more than two-thirds of its population – are in dire need of humanitarian aid, according to a UN estimate. The crisis has worsened, because access has become harder and funding is lower.
Since the start of this year there have been 40 attacks on aid workers in South Sudan - leaving 22 aid workers dead and 36 injured, according to the 2023 Aid Worker Security Report.
Peter Van der Auweraert, the UN Acting Humanitarian Coordinator for South Sudan, says most of those killed were South Sudanese nationals.
The humanitarian community there says it needs $1.7bn (£1.3bn) to target 6.8 million of the most vulnerable people.
In addition, the conflict in neighbouring Sudan has triggered an influx of over 220,000 refugees, returnees and third-country nationals into South Sudan since April.
