Over 90,000 Sudanese refugees have fled to Chad to escape the fighting between rival generals that has been raging for over a month. The United Nations High Commissioner for Refugees (UNHCR) has raised concerns over the rapid increase in refugees, estimating that around 90% of those fleeing are women and children. The rainy season, which is about to begin, will create further challenges for providing aid to the refugees. The UN has appealed for $3 billion to help those affected by the conflict in Sudan and neighbouring countries.
