The ITUC has expressed its deep concern about the unprecedented drought and famine in the Horn of Africa, in a letter to UN Secretary General Ban Ki-moon, calling on the UN to dramatically scale up action to deal with the on-going human tragedy. More than 12.4 million people in Djibouti, Ethiopia, Kenya and Somalia are currently affected by the famine, which is the most severe food crisis of its type in the world for some two decades.
