"To respond to the worsening humanitarian situation and help the people of South Sudan we are determined to use all available instruments and have therefore decided to mobilise today's additional assistance," he said.The funding will be spent on essential food and non-food items, as well as providing shelter, health, protection, water, hygiene and sanitation.
