A group of villains who called themselves The Weaponeers tried to take over the Central Saharan Republic in the name of their leader: Achmed Al-Khalid. This leader was never shown on-panel.
Based on his Muslim/Arabic name, the way his followers looked, and the predominantly Muslim location of these events, one can safely assume that Achmed Al-Khalid was intended to be a Muslim character.
