The United Nations is deeply worried about the impact of the fighting on the humanitarian situation in Sudan. After ten days of clashes, the UN Office for the Coordination of Humanitarian Affairs (OCHA) says there are acute shortages of food, water, medicines and fuel, and limited access to communications and electricity while the prices of essential items are skyrocketing. Meanwhile, thousands of Sudanese are fleeing the violence to South Sudan, Chad and Egypt as foreigners are evacuated to their home countries.
