United Nations (UN) Humanitarian Coordinator for Nigeria, Mr Matthias Schmale on Friday  describes the killing of an aid worker in northeast Borno State as deeply disturbing and sad. 
Schmale, in a statement said the shooting of the aid staff of an international humanitarian organisation in Damboa on Thursday by a soldier, was deplorable.
“Yesterday (Thursday)’s killing of a staff member of the humanitarian non-governmental organization Meědecins du Monde in Damboa, Borno State is deeply disturbing and sad,” he said.
The soldier opened fire on the female aid worker, shot his colleague soldier and injured a UN pilot.
But Schmale maintained all humanitarian staff working in north-east Nigeria deserve “fullest respect for their courage and commitment to stay and deliver life-saving assistance to people in need.”
The UN chief condole with the aid worker’s family and her colleagues. He also wished the wounded pilot a speedy recovery.
