The dusty buses keep coming, dozens a day, mattresses, chairs and baskets piled on top. They stop at schools hurriedly turned into camps, disgorging families who describe fleeing from ethnic Amhara militia in Ethiopia's Tigray region.

Four months after the Ethiopian government declared victory over the rebellious Tigray People's Liberation Front (TPLF), tens of thousands of Tigrayans are again being driven from their homes.

This time, it is due not to the fighting, but to regional forces and militiamen from neighboring Amhara seeking to settle a decadesold land dispute, according to witnesses, aid workers and members of Tigray's new administration.
