The charity Save The Children says almost 5,000 children displaced by the fighting in the Tigray region of northern Ethiopia, have been separated from their parents.
Many have been arriving at displaced people’s camps or informal shelters.
Save the Children says they’re are vulnerable to hunger as well as physical and sexual violence.
It says humanitarian organisations have been unable to reach most parts of the region, and the children are having to fend for themselves.
Six months after the war began in Tigray, 1.7 million people have fled their homes.
The United Nations continues to warn of the worsening humanitarian situation in the region.
It is also warning that while data remains limited, there are indications of “alarming” levels of malnutrition in Tigray affecting children as well as pregnant and breastfeeding mothers.
