A military helicopter has crashed in Ethiopia's Oromiya region, killing all 18 people aboard, including 15 soldiers, state-affiliated news agency Fana reports.
The other three dead in Thursday's crash were civilians, Fana said.
Oromiya regional cabinet minister Addisu Arega confirmed the Fana report and tweeted: "All passengers on board died. The cause is under investigation. Our condolences to the families."
The helicopter was flying from the eastern Ethiopian town of Dire Dawa and headed to Bishoftu around 60km south of the capital Addis Ababa, Addisu said.
