The Cabo Delgado province in northern Mozambique has seen increasing violence over the past several years in the face of an Islamist group known locally as Al-Shabab (unrelated to Al-Shabab in Somalia). The group pledged allegiance to ISIS/ISIL in 2018, but the extent to which the two groups collaborate is hotly debated. The fighting has led to hundreds of thousands of refugees and IDPs (internally displaced persons) as thousands die in the violence. Reports indicate Al-Shabab has forced young men to join and taken young women into slavery and forced marriage. Accusations of war crimes have been leveled against the Islamists, the Mozambican armed forces, and the South Africa-based Dyck Advisory Group, which is operating in the country to assist the government.
