Rebellious forces from the Tigray region killed 120 civilians over two days in a village in Ethiopia's Amhara region, local officials told Reuters on Wednesday.

The killings in a village 10 kilometers (6 miles) from the town of Dabat took place on Sept. 1 and 2, said Sewnet Wubalem, the local administrator in Dabat, and Chalachew Dagnew, spokesperson of the nearby city of Gondar.

A spokesperson for Tigrayan forces did not immediately respond to a request for comment on what is the first report of Tigrayan forces killing a large number of civilians since seizing territory in Amhara. Tens of thousands of people have fled their homes in the region as Tigrayan forces have advanced.

"So far we have recovered 120 bodies. They were all innocent farmers. But we think the number might be higher. There are people who are missing," Sewnet told Reuters by phone.

Chalachew said he had visited the burial area in the village and that children, women and elderly were among the dead.

He said the killings were during the Tigrayan forces' "short presence" in the area, and it was now under the control of the Ethiopian federal army.

War broke out 10 months ago between Ethiopia's federal troops and forces loyal to the Tigray People's Liberation Front (TPLF), which controls the Tigray region.

Since then, thousands have been killed and more than 2 million have fled their homes. Fighting spread in July from the Tigray region into the neighboring regions of Amhara and Afar, also in the country's north.

Amid the conflict, relations between the ethnic Amharas and Tigrayans have deteriorated sharply.

During the war, regional forces and militiamen from the Amhara region have sought to settle a decades-old land dispute between the Amhara and Tigray regions.

Amhara forces have seized control of western parts of Tigray and driven tens of thousands of Tigrayans from their homes. Though the Tigrayan forces have seized back most of the Tigray region, they have not taken back the heavily militarized and contested area of western Tigray.

The United States government's humanitarian agency said last week Tigrayan forces had in recent weeks looted its warehouses in parts of Amhara.

The United Nations has said a de facto aid blockade on the Tigray region, where some 400,000 people are already in famine conditions, has caused a humanitarian crisis.

The Ethiopian government has repeatedly denied allegations by the U.N. and Western governments that it is deliberately impeding the delivery of lifesaving assistance. On Sunday, a U.N. convoy of trucks bearing food and other aid was permitted to enter Tigray for the first time since Aug. 20.
