Nigerian military base shooting kills 2

ABUJA, Nigeria — A Nigerian soldier opened fire in a military base, killing an aid worker and a fellow soldier in the country’s northeast region where troops are fighting decade-long extremist violence, authorities said Friday.

Samson Nantip Zhakom, a spokesman for the Nigerian army, said troops at the Damboa base in Borno province took steps to “immediately neutralize” the unidentified soldier, indicating that he had been killed.

A helicopter pilot for the U.N. Humanitarian Aid Service was injured in the shooting and is in stable condition, said Zhakom of the incident which took place on Thursday. The aid worker who was killed had worked for the group Medecins du Monde, or Doctors of the World, according to the U.N. in Nigeria.

“A detailed investigation into the incident and subsequent remedial actions have commenced into the highly regrettable incident,” said Zhakom.

The shooting prompted the U.N. air service — which transports humanitarian workers and supplies in the troubled region — to suspend helicopter operations in the area.
