Boko Haram insurgents killed at least 20 soldiers and more than 40 civilians and injured hundreds in twin attacks in northeast Nigeria of Borno said residents and a civilian task force fighter.
The attacks, in the Monguno and Nganzai local government areas, came just days after militants killed at least 86 people in Gubio.
The sources said hundreds of civilians were injured in the crossfire, overwhelming the local hospital and forcing some of the injured to lay outside the facility awaiting help.
The sources said the militants also set fire to the local police station and burned down the United Nations humanitarian hub in the area.
UN spokesperson said the facility sustained only light damage. Fighters distributed letters to residents, in the local Hausa language, warning them not to work with the military and humanitarian organizations.
Troops of Sector 3 and Air Task Force Operation LAFIYA DOLE successfully repelled an attack on Monguno town and inflicted heavy casualties on Boko Haram and ISWAP terrorists who attempted to breach Munguno Town in Borno State.
A statement by the Coordinator Defence Media Operations Major General John Enenche noted that during the attack 20 terrorists were killed and 4 gun trucks were destroyed.
