In March 2019 Chadian President Idriss Déby announced that the border would close, citing the crossing of the frontier by Libyan-based anti-government rebel groups into Chadian territory (most notably the Military Command Council for the Salvation of the Republic; French: "Conseil de commandement militaire pour le salut de la République", abbreviated CCMSR) and the continuing instability caused by the civil war in Libya. As part of Operation Barkhane France has provided assistance to the Chadian Army with guarding the border, including launching air strikes against anti-government rebels.
