The Islamic State in the Greater Sahara (ISGS) splintered off from
MOJWA in the mid-2010's and became an official Islamic State branch in 2016 with
Adnan Abu Walid al-Sahrawi as leader. They launched their first attacks in Niger in October 2016, on the
Koutokole prison and possibly in
Tazalit. Three days prior to the attack in Wanzarbe, the Nigerien government declared a state of emergency in Tillaberi and
Tahoua Region. == Attack ==
