Troops have killed a soldier who shot an aid worker on Thursday in Damboa LGA of Borno.

Samson Zhakom, assistant director of army public relations, in a statement on Thursday, said the soldier also killed another soldier and injured a helicopter co-pilot before he was neutralised.

Zhakom said the injured co-pilot has been stabilised, and that investigation has commenced into the regrettable incident.

“The theatre command Operation Hadin Kai regrets to inform the general public of a sad occurrence at one of our military bases today. A soldier shot and killed a staff of one of the NGOs providing humanitarian support in the North East,” the statement reads.

“Same soldier also killed another soldier and injured the co-pilot of one of the UN helicopters. Own troops on the ground immediately neutralized the errant personnel.

“The injured co-pilot has been stabilized while the corpses of the deceased have been moved to the 7 Division Hospital. Detailed investigation into the incident and subsequent remedial actions have commenced into the highly regrettable incident.

The development comes hours after Audu James, a brigadier-general in the Nigerian army, was killed in a car crash in Lagos.
