Belmokhtar claimed responsibility for another terrorist attack on 23 May 2013. In this attack, a French-owned uranium mine in Arlit, Niger, as well as a military base 150 miles away in Agadez, were attacked by suicide bombers with truck bombs. Experts saw no reason to doubt the claim of responsibility. Anouar Boukhars of the Carnegie Endowment for International Peace saw the bombing as retaliation for the earlier French intervention in the Northern Mali conflict.
