A Nigerian soldier shot and wounded a United Nations helicopter co-pilot on Thursday before going on to kill a humanitarian worker and a fellow soldier at a military base in northeastern Nigeria, the army and a witness said.
The Nigerian Army said in a statement that one of its members shot and injured a helicopter co-pilot from the United Nations Humanitarian Air Service (UNHAS) in the north east, where the military is battling an Islamist insurgency.
Army spokesman for the anti-insurgency operation Samson Nantip Zhakom said the unnamed soldier went on to shoot and kill a worker from one of the organisations providing humanitarian support in the region, before turning on a fellow soldier.
