As Sudan has entered its tenth month of conflict, United Nations agencies launched a US$4.1 billion appeal Wednesday to provide urgent aid for 14.7 million people inside Sudan and 2.7 million refugees and host communities in five neighboring countries. Due to the war, half of Sudan’s population – some 25 million people – needs humanitarian assistance and protection. More than 1.6 million people have fled across Sudan’s borders to the Central African Republic, Chad, Egypt, Ethiopia and South Sudan.
