The suspected ringleader of Saturday’s failed coup attempt in Ethiopia’s Amhara region is on the run, a senior security official has told the BBC.

Six people, including the bodyguard who killed the army chief, are now known to have died in the unrest.

Flags are flying at half-mast after the federal government declared a day of mourning to mark the deaths.

Prime Minister Abiy Ahmed has urged Ethiopians to unite against “evil” forces set on dividing the country.

Both the army chief Gen Seare Mekonnen and Amhara governor Ambachew Mekonnen, who was also killed, were seen as close allies of the prime minister.

A heavy contingent of pro-government forces has been deployed in Amhara’s capital, Bahir Dar, and the federal capital, Addis Ababa.

The internet has been shut across the country, days after services resumed following an unexplained blackout of more than a week.
