Al-Qaeda-linked jihadist group Jama'a Nusrat ul-Islam wa al-Muslimin (JNIM) claimed responsibility for an attack on a military base in Mali on Sunday that had killed over 30 soldiers. The group seized the base in Boulkessi, near border with Burkina Faso. On Monday, JNIM, active in West Africa's Sahel region, assaulted a military airport and Russian mercenaries in Mali's Timbuktu.
