In a statement released yesterday, the UN said the steady deterioration of security, particularly in the past two months, was affecting the population and directly targeted the humanitarian community.
It explained that repeated kidnappings of humanitarian staff and the killing of peacekeepers as well as vehicle hijackings and banditry seriously impeded the overall humanitarian access in the region.
Security infractions against aid workers put at risk the continued implementation of humanitarian work in the region.
The reduction of access due to insecurity resulted in a complete suspension or a serious reduction of activities and delivery of assistance by humanitarian agencies.
The U.N. mission called on the Sudanese authorities to make a concerted effort to arrest and prosecute people who attack, abduct and rob humanitarian workers.
