The Qandala campaign began when the Islamic State in Somalia (ISS) attacked and captured the town of Qandala in Bari, Puntland, Somalia on 26 October 2016. This takeover resulted in the displacement of over 25,700 civilians and an eventual counter-offensive by the Puntland Security Force, which succeeded in driving ISS from Qandala on 7 December, and thereafter government units continued to attack the militants' hideouts in the nearby mountains until 18 December. The fall of Qandala was the second time that an Islamic State of Iraq and the Levant (ISIL)-affiliated group had captured a town in Somalia, but whereas the first takeover had lasted only for a very short time, ISS had managed to hold Qandala, a town of both major strategic as well as symbolic importance, for over a month.

The Islamic State – Somalia Province or Abnaa ul-Calipha is an Islamic State–affiliated group that primarily operates in the mountainous areas of Puntland, and which has also claimed responsibility for several terrorist attacks throughout the rest of Somalia. Led by Sheikh Abdul Qadir Mumin, the group is estimated to have up to 300 active fighters. Since its formation, ISS probably managed to take control of a small, sparsely populated territory in northern Somalia's mountainous hinterland, though it was not acknowledged as official province ("Wilayat") by IS's central leadership until December 2017. Since then, it has sometimes been called Somalia Province by pro-IS media. ISS is also the declared enemy of al-Shabaab, which considers the Islamic State a significant threat to its own predominance among Jihadist factions in Somalia.
