In August 2018, the Chadian government moved region boundaries so that Miski was no longer part of the Tibesti region, where Teda people are a majority; instead, it became part of Borkou region, where the Teda are a minority. Local officials who objected to the change were fired. In response, a local self-defense committee was formed. After a month of fighting between the self-defense committee and the Chadian national army, the army retreated from the town.
