Six aid workers were ambushed and killed in South Sudan last week. The aid workers were travelling from the country’s capital, Juba to Pibor. The victims included three South Sudanese and three Kenyans. The U.N says, close to 80 aid workers have been killed in South Sudan since the beginning of the conflict in December 2013. The continued killing of aid workers severely affects the provision of humanitarian assistance to vulnerable people in a country facing famine, and political instability. The attack has continued to draw strong criticism across the world.
