The Abubakar Shekau faction of Boko Haram and members of the Islamic State of the West African Province (ISWAP) fought a deadly gun battle.
Both factions have been at war since 2016, when ISWAP split out of the Shekau-led leadership party.
Abu Musad Al-Barnawi, then leader of the ISWAP, had said that the group of Shekau would be defeated by the Nigerian army.
According to Al Thabat, an al-Qaeda-affiliated media outfit, the recent crisis between factions broke out in Sunawa, a town on the Nigerian-Niger border, where several of the fighters killed each other.
Al Thabat said the battle occurred after ISWAP abducted dozens of women linked to the Shekau-led group.
Reacting to the development, Mohammed Yerima, army spokesperson, said the incident has exposed the disorganised nature of Boko Haram.
“The Nigerian army in recent operations under the leadership of the Chief of Army Staff (COAS), Major General Ibrahim Attahiru, has continued to dismantle all logistics and operational bases of the insurgents along the Lake Chad Basin axis and Sambisa forest area,” he said in a statement Monday.
“The troops in one of its operations along Sambisa forest discovered and destroyed Abubakar Shekau’ farm and rescued abducted victims.
“The Nigerian army wishes to use this medium to reassure Nigerians of the determination of troops to clear the remnant terrorists out of the Nigerian territory.”
The military has in recent months recorded successes in its war against the insurgents.
