Ethiopian soldiers killed nine civilians and injured 12 after mistaking them for rebels near a town along the country’s border with Kenya, state media said on Sunday.

“Nine civilians were killed and 12 others were injured during an operation that was launched with faulty intelligence,” Ethiopian military was quoted as saying.

According to this report, a high-level military delegation had been dispatched to the area to launch an inquiry.

The incident took place at a time when violence has continued to plague Ethiopia, mostly in Oromiya.

Last month, government imposed a six-month, nationwide state of emergency to crack down on unrest in Africa’s second most populous nation.

This came a day after Prime Minister Hailemariam Desalegn announced his resignation in what he said was a bid to pave the way for reforms.
