The government of Ethiopia's Afar region says more than 300,000 people have been displaced by warfare there since December and it accused Tigrayan forces of killing civilians and looting.
The United Nations has said that the fighting in Afar was blocking the delivery of food to neighbouring Tigray region, where several hundred thousand people are living in famine conditions.
"People are fleeing in absolute fear in all directions," said an aid worker in Afar, who asked not to be named.
