The military was deployed in the Ethiopian capital on Wednesday, as armed gangs roamed neighbourhoods in a second day of unrest that has claimed more than 80 lives and deepened political divisions in Prime Minister Abiy Ahmed’s political heartland.

The protests were sparked by the assassination of popular musician Haacaaluu Hundeessaa on Monday night and spread from Addis Ababa to the surrounding Oromiya region.

The killing tapped into grievances fuelled by decades of government repression and what the Oromo, Ethiopia’s biggest ethnic group, describe as their historic exclusion from political power.
