Reports say the assailants sneaked into the town on Tuesday night through Chakawa village, killing and burning houses.
The attackers also beheaded seven civilians, burnt two houses before leaving.
Seven men were killed by the insurgents during the attack, while two women got injured and are receiving medical attention.
