ABUJA, May 22 (Xinhua) -- Four internally displaced persons (IDPs) in Nigeria were killed by terror group Boko Haram in an attack in the country's northeastern state of Borno on Saturday, local police confirmed on Monday.
The victims, who were hunters, had left their camp in Maiduguri on a hunting expedition when they were ambushed late Saturday, Borno State police chief Damian Chukwu told Xinhua.
"Three of them were beheaded and one other was shot dead," Chukwu said.
Another internally displaced person who joined the deceased in their hunting for animals in the bush has been declared missing, the police officer noted.
An investigation into the killing is underway, he said, adding the attention of the military had been drawn to the development.
The killing was the first incident since internally displaced persons' camps were officially opened in Maiduguri, the Borno State capital.
