Abubakar Shekau, leader of one of Boko Haram's Islamist factions, claimed a series of attacks in northeastern Nigeria in a new video message received Friday by AFP.
According to the jihadist leader, his fighters are responsible for an attack Monday against the army in the village of Kumshe, near the Cameroon border.
"We are responsible for attacks in Kumshe, Gulumba and other villages in recent days," said Shekau in this short video, her first appearance since July.
The video surprisingly uses the Arabian logo and the ISAF black flag, a faction usually rivaling Shekau's Boko Haram faction, which may indicate a recent rapprochement between these two. groups.
The Kumshe attack had already been claimed by ISWAP on Wednesday, according to the SITE jihadist movement monitoring site.
If the two factions now act together, this could be even more problematic for the Nigerian military who still can not reduce Boko Haram, which has increased its attacks in recent weeks.
The Islamist insurgency has killed more than 27,000 people since 2009 and some 1.8 million people are still displaced.
