The response plan, developed in coordination with regional and country level non-governmental and intergovernmental partners, is a migrant-focused humanitarian and development strategy for vulnerable migrants from the Horn of Africa, specifically those from Somalia, Djibouti and Ethiopia, moving to and from Yemen. The plan targets some 81,000 people. Irregular migration from the Horn of Africa to the Gulf countries has been steadily increasing over the past few years, with approximately 100,000 people entering Yemen, a major transit point on this route, in 2017. Often, migrants and refugees cross the Gulf of Aden from Djibouti or Somalia, arriving in Yemen with the support of smugglers.
