At least 108 civilians have been killed by airstrikes in northern Ethiopia in the past two weeks, the United Nations (UN) said.
Some 75 others had been injured in strikes allegedly carried out by the Ethiopian air force, the UN human rights office said.
The federal government has previously denied attacking civilians in Tigray.
On Thursday, Addis Ababa asked the head of the World Health Organization (WHO), Dr Tedros Adhanom, to stop talking about the situation in Tigray, which he has described as “hell-like”.
Dr Tedros, who comes from the region, said a blockade was preventing medicines from reaching people in the area.
