About 4.1 million people are internally displaced and 1.4 million are living in the region as refugees or asylum seekers, according to the OCHA document.
The analysis of the agency reflects concern about food insecurity in the region that affects 14.6 million people in the area.
Another alarming information in the UN report refers to the situation in Somalia where 1.2 million infants or pregnant women or those breastfeeding their children 'will suffer from acute malnutrition.'
The document also states that the trend will continue in 2018 due to 'the combination of drought, conflicts and insecurity that increase the concerns (of people) for their safety' and denounces that 'sexual and gender-based violence and violence against children will continue.'
