Ethiopia's Prime Minister Abiy Ahmed has sacked and replaced two of the country's most senior defence and security staff.

Gen Samora Yunis, described as Ethiopia’s “most prominent military figure” by a top prime ministerial aide, has been replaced as army chief of staff by Gen Seare Mekonen.

Air Force Commander Gen Adem Mohamed has been appointed the new head of Ethiopia's Intelligence and Security Service, replacing Getachew Asefa who was in post for 17 years.

The prime minister has brought in many reforms since April.

The outgoing army chief, Gen Samora, was due to retire in a few months time.

He fought with the rebels who overthrew Mengistu Haile Mariam in 1991 and brought Meles Zenawi to power.

For the next few decades he was Mr Meles’ close ally and the key figure in the much-feared security establishment.

He leaves his post just two months after Mr Abiy came into office in a bid to end anti-government protests.
