The United Nations Children's Fund (UNICEF) warns the drought in the country's east and south could turn into a full-blown famine without immediate action. The agency says it is facing difficulties in sourcing financing and aid to back its humanitarian operations in the drought-stricken regions. It reports that severe acute malnutrition has risen sharply in these areas. There has been a 47pc increase in the Somali Regional State, according to UNICEF. The UN says the drought is the "worst in four decades" and estimates that seven million people are in need of emergency food aid. Last month, the federal government and the World Bank signed an agreement for 715 million dollars in funding for the fight against rising food insecurity.
