Yunis fought for the military wing of the
Ethiopian People's Revolutionary Democratic Front, playing a leading role in the
Battle of Shire (18–19 February 1989). He was made Chief of General Staff in 2001, when he replaced
Tsadkan Gebretensae. According to
Human Rights Watch, credible sources identify General Samora as a member of the leadership group which met in
Jijiga following the attack on oilmen at
Abole on 24 April 2007, to determine an appropriate response to this raid. On 7 June 2018, it was announced that Yunis would be replaced by
Seare Mekonen as the new Chief of General Staff. In 2017, he received the
Order of the Two Niles from Sudan. ==References==
