Ethiopian police have unearthed a mass grave with an estimated 200 bodies in an area between the country's Oromia and Somali regions, according to state-affiliated media.
Fana Broadcasting Corporation said on Thursday the grave was found during an investigation into atrocities allegedly carried out by a paramilitary force known as the "Liyu Police" that were seen as loyal to Abdi Mohammed Omer, the former president of the Somali region.
Adbi was forced to resign on August 6 and was later arrested after fighting broke out in the provincial capital, Jigjiga, and surrounding towns. He is now in detention facing trial for alleged human rights violations.
According to Fana, police were granted 14 days to unearth and do forensic examinations on the bodies.
"If these mass graves are proved to be related to a systematic attack to the local populations, certainly, we are looking at a case of war crimes and crimes against humanity," Awol Allo, a lecturer at Keele University's School of Law and an expert on Ethiopia, told Al Jazeera.
