In Chad, a northern rebel movement is getting more attention, particularly after its recent attack on Kouri Bougri* – enough attention that President Idriss Deby referenced them in his 20 August Eid al-Adha/Tabaski speech, although they quickly rejected his call for them to lay down arms.
The movement is called the Military Command Council for the Salvation of the Republic (French acronym CCMSR). RFI says it is “the best armed” of Chad’s rebel movements, and quite possibly also the largest. Formed in 2016 in southern Libya, it includes a number of rebels who previously fought with other groups.
The CCMSR’s secretary-general is Mahamat Hassan Boulmaye. In October 2017, Boulmaye, his spokesman Ahmat Yacoub Adam, and external affairs secretary Abdraman Issa Youssouf, were arrested in Niger (reports conflict as to whether it was near Agadez or in Niamey; Niamey is the version the CCMSR gave). They may have been extradited to Chad – specifically to the Koro Toro prison – but as of May 2018 both Chadian and Nigerien authorities refused to confirm that. The interim secretary-general is Mahamat Tahir Acheick, about whom I could find very little information. You can listen to a French audio message from Boulmaye here, and David Kampmann has more background on the movement here.
The CCMSR’s activities have affected Libya as well. In March 2018, Khalifa Haftar’s Libyan National Army conducted “air raids [that] targeted a rebel-held roadblock 400km southeast of Sebha, as well as other positions in an oasis in the Terbu region 400km farther south.”
The history of rebellions in Chad is too complex to summarize here, but a good place to start for background is Marielle Debos’ Living by the Gun in Chad.
