Jihadists connected to the Islamic State West Africa Province (ISWAP) militant group killed at least 20 soldiers and 40 civilians over the weekend in twin attacks in the restive northeast Nigerian state of Borno, residents and security sources said.
Dozens of militants clashed with soldiers and members of a government-backed militia in Monguno near Lake Chad and in Nganzai, just days after militants killed at least 69 people in a village raid in Gubio.
Local sources told Reuters news agency that the militants also set fire to the local police station and burned down the United Nations' humanitarian facility in the area, although a UN spokesperson said the establishment sustained only light damage.
According to Reuters, militants distributed letters to residents, warning them not to work with the military, white Christian westerners or other "non-believers."
Twin attacks
Militants also raided Nganzai at about the same time on Saturday, according to two residents and one Civilian Joint Task Force (CJTF) fighter.
