(BBC) – Ethiopian security forces used extrajudicial killings, mass arrests and torture in efforts to suppress an armed group, the Oromo Liberation Army, in 2019, Amnesty International says.
This was the year that Prime Minister Abiy Ahmed won the Nobel Peace Prize.
He has been praised for his reforms, but they may have lifted a lid on ethnic tensions.
The BBC has tried to contact the authorities to respond to the report but they have not reacted.
Among the allegations made by Amnesty International are the illegal killings of 39 people in Oromia regional state.
Through witness testimony, it details how three victims were taken out of police cells and shot dead.
In another incident, a man was killed in front of a crowd after his phone rang during a public meeting, according to witnesses quoted by the rights group.
The security forces are also accused of rounding up people they believed were supporters of the OLA.
The OLA is a breakaway faction of the Oromo Liberation Front, a former separatist rebel group which laid down arms following peace talks with Mr Abiy.
The report also highlights the alleged role of security forces in inter-communal violence in January 2019 in Amhara state, north-west Ethiopia.
