Unprecedented levels of suffering not seen since the end of the Second World War has prompted a US $22.2 billion appeal for funds - the biggest humanitarian appeal yet by the United Nations.
Launching the appeal in Geneva, the UN's aid chief Stephen O'Brien said that the objective was to help 93 million people with immediate needs.
From Yemen to Syrian and from South Sudan Lake Chad to Syria, the appeal covers a total of 33 countries.
Daniel Johnson has more.
