Relatives of a prominent Ethiopian army general say they fear for his safety after he went missing two days ago in the capital, Addis Ababa.
Brigadier General Tefera Mamo, former commander of the Amhara Special Forces that are allied to the federal army in its fight against rebels from the province of Tigray, had been critical of the government after he was removed from his position in February.
Gen Tefera Mamo left his home in Addis Ababa to meet a friend on Monday but never returned.
His wife has told the BBC she fears he has been abducted as she has not heard from him since.
He first came to public attention in 2009 when he was accused of plotting a coup against former Prime Minister Meles Zenawi and was thrown in jail. He was released in 2018 when the country was in the midst of political transition.
