Abuja, Nigeria (CNN) At least 65 people are dead following a suspected attack by Boko Haram on a funeral gathering in northeastern Nigeria, according to local officials.

The attack occurred Saturday during a burial in the Nganzai district, near the Borno state capital, Maiduguri, local government chairman Muhammed Bulama said.

Twenty-one people were initially killed during the burial ceremony, Bulama said. An additional 44 people were killed when villagers ran after the assailants, the official said.

At least 10 people were injured in the attack. Eight of them were critically wounded and were being treated at an area hospital, he said.

Boko Haram militants have inhabited the northern states of Nigeria for the past decade. The terror group says its aim is to impose a stricter enforcement of Sharia law across Africa's most populous nation, which is split between a majority Muslim north and a mostly Christian south.
