Nigeria and neighboring countries have been suffering from attacks by Boko Haram terrorist group, including bomb blasts.
In 2016 the military retook most of the territory, which the terrorist group Boko Haram managed to capture after it launched military operations in 2009, and the government declared the Boko Haram insurgency defeated. However, the Islamist group has continued its suicide bombings.
Boko Haram is a Nigerian militant group which aims to establish an Islamic state in Nigeria’s northeast and rejects any Western values and principles.
