Boko Haram militants have shot dead 18 women at a funeral in Nigeria's northeast, rampaging through a village, setting houses on fire and shooting at random, witnesses and local government officials said on Friday.

The attack took place at about 5 p.m. (12 p.m. ET) on Thursday in the village of Kuda in Adamawa State. Resident Moses Kwagh told Reuters that people waited until three hours after the attack and had then counted 18 women's bodies.

Some women were still missing, he said.

A police source confirmed the attack but said it was not yet clear how many people had been killed. The military did not respond to a request for comment.

State lawmaker Emmanuel Tsamdu told Reuters: "I am yet to get the details on how it happened and the real number of people killed. I have sent hunters to go to the area and get me the details because people are afraid to go to the village."

Kuda is close to the Sambisa Forest, a vast colonial-era game reserve where Boko Haram militants hide in secluded camps to avoid the Nigerian military. The village was attacked by Boko Haram militants in February.

Under President Muhammadu Buhari's command and aided by Nigeria's neighbors, the army has recaptured most of the territory seized by Boko Haram, but the group still regularly stages guerrilla attacks.

"When we said that Boko Haram is still in this place some people sit in Abuja and claim that there is no more Boko Haram, but see what has happen," Kwagh said.
