Islamic militants killed at least 20 soldiers and more than 40 civilians and injured hundreds in twin attacks in northeast Nigeria's Borno state Saturday, residents and a civilian task force fighter said.
The attacks, in the Monguno and Nganzai local government areas, came just days after militants killed at least 69 people in a raid on a village in a third area, Gubio.
Two humanitarian workers and three residents told Reuters that militants armed with heavy weaponry including rocket launchers arrived in Monguno, a hub for international non-governmental organizations, at roughly 11 a.m. local time. They overran government forces, taking some casualties but killing at least 20 soldiers and roaming the area for three hours.
The sources said hundreds of civilians were injured in the crossfire, overwhelming the local hospital and forcing some of the injured to lie outside the facility awaiting help.
The militants also burned down the United Nations' humanitarian hub in the area and set on fire the local police station. Fighters distributed letters to residents, in the local Hausa language, warning them not to work with the military or international aid groups.
Militants also entered Nganzai about the same time Saturday, according to two residents and one Civilian Joint Task Force (CJTF) fighter. They arrived on motorcycles and in pickup trucks and killed more than 40 residents, the sources said.
A military spokesman did not answer calls for comment on the attacks. U.N. officials could not immediately be reached for comment.
Boko Haram and its offshoot, Islamic State West Africa Province (ISWAP), have killed thousands and displaced millions in northeastern Nigeria. ISWAP claimed the two Saturday attacks, and the Gubio attack.
