The brutal murder of 122 aid workers in 2008 and ambushes, murders of aid workers and kidnapping elsewhere are indicative of the fact that aid workers have increasingly found themselves the targets of deliberate violence and have captured headlines. This changing nature of armed conflicts has resulted in increased need to safeguard civilians including humanitarian personnel which is reflected in the emerging protection of civilian agenda. This project reviewed the prevailing explanations, assumptions and researched on the reasons why humanitarian workers experience these threats and attacks. This research work considers the security of aid workers in Darfur. It specifically examines the extent to which traditional principles of humanitarian action provides security for humanitarian personnel. Some scholarly articles and literature on security of humanitarian actors already exist but this one dealt with the case of Non-governmental organizations working in Darfur-Sudan. The shooting of six nurses of the international committee of the Red Cross’ (ICRC) in their beds while they were asleep in 1996 accelerated a focus on security amongst relief and development actors. It precipitated the notion of security as an essential element of humanitarian operations and resulted in the development of security training manuals and management strategies. This project dealt with the reason for the rise in violent attacks against aid workers and went further to look at the ways in which humanitarian organizations have been responding to these security threat.
