International child migration has become a modern form of brutality. Ethiopia is also one of the source countries for thousands of young migrants leaving their villages in search of better opportunities elsewhere. The article aims to explore the experiences of Ethiopian unaccompanied and separated migrant children in Yemen. The study was conducted using constructivist research paradigm qualitative hermeneutic phenomenological inquiry with a cross sectional exploratory study design. Twelve purposefully selected returnees unaccompanied and separated migrant children from Yemen, with the registered age of sixteen and seventeen, had participated in the study. Data collected through in-depth interviews, focus group discussion and observation were analyzed thematically. The finding indicated dreadful experiences such as detention; bomb attack; physical abuses; emotional problems; imprisonment; starvation; military recruitment; and sexual abuse which were part of the lives of unaccompanied and separated migrant children in Yemen. The study concluded that the experiences of the migrant minors in Yemen were against the universally declared basic human and child rights that recognize the inherent dignity of all human beings and the developmental needs of children in particular. Findings implied points for comprehensive social work practice, and further research endeavors on the topic under investigation.
