The United Nations Children’s Fund on Monday, Dec. 7, 2020, launched a global appeal for a record $2.5 billion of emergency assistance for the Middle East and North Africa, saying the funds were necessary to respond to the needs of millions of children across a region hit hard by conflict, natural disaster and the coronavirus crisis.
