207 killed in Wednesday Ethiopia attack: rights commission
The independent government body had on Wednesday said 100 people were killed in their sleep and crops burned in a pre-dawn assault in the Metekel area of the Benishangul-Gumuz region.
"133 of the victims were adult men and 35 were adult women. Seventeen children, one of whom a six-month-old baby, and 20 elderly persons were killed," the EHRC said in a statement posted to Twitter late Friday.
Mostly inhabited by ethnic Shinasha, Oromo and Amhara people -- the last two making up Ethiopia's most numerous groups -- the Metekel area has suffered a string of deadly attacks in recent months.
Local leaders blame ethnic Gumuz people for the violence.
Following Wednesday's attack, "effort is underway to identify the victims with the help of survivors and identity cards," the EHRC said.
The body repeated its appeal for "relevant authorities to provide urgently humanitarian assistance to the victims and persons displaced by the attack."
It added that around 10,000 had fled the Bekuji Kebele area and made for the city of Bulen, around 40 kilometres (25 miles) away, which is already sheltering "thousands of displaced persons".
"Bulen city is overwhelmed. The roads leading to the city are still teeming with displaced persons and their herds of cattle," one eyewitness told the commission.
Regional authorities said on Thursday that troops had killed 42 armed men alleged to have taken part in the massacre, without giving details about their identities.
"The massacre in the Benishangul-Gumuz region is very tragic," Ethiopian Prime Minister Abiy Ahmed said in a Twitter post on Thursday, conceding the government's efforts to solve the problem "had not yielded results".
In October, he had said that fighters "armed and trained" in Sudan's neighbouring Blue Nile state were behind the violence and urged Khartoum to tackle the problem.
Abiy claimed that the latest attack had been aimed at "dividing the significant force" deployed to the country's dissident northern Tigray region.
There is no known link between the violence in Benishangul-Gumuz and military operations in Tigray.
Thousands have been killed in the Tigray conflict, according to the International Crisis Group think tank, and more than 50,000 people have fled over the border into Sudan.
