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