Members of the terrorist group, Boko Haram, have reportedly killed 16 civilians and 11 soldiers in Borno State.
According to reports from the military, some Boko Haram insurgents ambushed a military convoy near Mauro Village in Benisheikh district.
"Our men on patrol fell into a terrorist ambush ... which claimed 11 soldiers and wounded 16 others.
"Two other soldiers are still missing," an officer, who asked not to be identified, said.
He added, "The terrorists made away with 11 AK-47 rifles and anti-aircraft guns mounted on the gun truck."
Another attack by the insurgents was reported that day, as they allegedly opened fire on a vehicle in Frigi Village, killing one person and injuring another.
The insurgents were also reported to have killed two military men in Gubio, 80 kilometres away from the state capital, Maiduguri. They were also said to have stormed an Internally Displaced Persons (IDP) camp in Banki, a town near the border of Nigeria-Cameroon.
The religious sect killed two residents and injured three vigilantes guarding the area. The decade-long Boko Haram insurgency has claimed the lives of 35,000 people and displaced around two million from their homes in North-East Nigeria.
The violence has spread to neighbouring countries, including Niger, Chad and Cameroon, prompting a regional military coalition to fight the insurgents.
