BAUCHI, Nigeria–Four people were killed when a United Nations World Food Programme (WFP) aid convoy was ambushed in northeast Nigeria, a WFP spokeswoman said on Sunday, in the latest attack in the region as the conflict with Boko Haram nears its ninth year.
Attacks on aid workers are relatively rare in the conflict with the Islamist insurgency, compared with assaults on the military and civilians in Nigeria’s northeast.
