The Islamic State group has said it carried out attacks committed up to two months ago in the Sahel - but failed to comment on the reported death of its regional leader there.
Adnan Abu Walid al-Sahrawi formed Islamic State in the Greater Sahara (ISGS) in 2015, and on Thursday French President Emmanuel Macron announced his death at the hands of French forces.
The group and its jihadist rival al-Qaeda are blamed for most attacks in the region, including the targeted killing of French aid workers in 2020.
The IS group's weekly newspaper, al-Naba, claimed attacks against the army and pro-army "militias" in Niger, against al-Qaeda rivals in Mali and Burkina Faso, and against "spies" in Mali - covering a period between early July and early September.
It is typical of IS claims from the Sahel to be weeks and even months old.
In its latest al-Naba report, the group reiterated that such delays were caused by "the security and technical circumstances [affecting] the mujahidin" on the ground.
