Ethiopia lies across the Red Sea from Yemen. One of the most populous African nations, it is landlocked on the semi-arid Horn of Africa by Eritrea, Djibouti and Somalia. In the west, the Blue Nile flows from its mountain peaks to Sudan. South Sudan and Kenya border the south. After his election in 2018, Prime Minister Abiy Ahmed, a confessing Christian of the largely Muslim Oromo tribe, successfully brought peace to extended internal tribal conflicts and with neighboring Eritrea. Yet, over the past year these resurfaced when forces of the small northern Tigray tribe waged a civil war. (It previously held power in Ethiopia for over 30 years.) Armed conflict has displaced millions and destroyed crops and herds, resulting in hunger and instability. Also, the south is suffering food shortages from severe drought.
