From the Document: "An armed Islamist insurgency in Mozambique--launched in 2017 with an attack on several police posts in Cabo Delgado province, in the country's north--has burgeoned. [...] The insurgents, locally dubbed Al Shabaab ('the youth,' also the name of a separate Al Qaeda-linked Somali group), also are known as Ahlu Sunna Wa-Jamo ('Adherents of the Sunnah' or ASWJ; spellings vary) and by other names. In 2019, ASWJ reportedly pledged allegiance to the Islamic State (IS, also known as ISIS), which often claims and lauds the group's attacks and counts it as a member of its IS Central Africa Province (ISCAP), together with affiliates in the Democratic Republic of Congo (DRC) and Somalia. Some observers have questioned the extent and import of ASWJ-IS ties, but U.N. global terrorism monitors and U.S. officials assert that operational links exist between them. In March 2021, the State Department, labeling ASWJ as ISIS Mozambique, designated the group as a Foreign Terrorist Organization, and also named as a Specially Designated Global Terrorist a Tanzanian whom officials identified as the group's leader. These actions ban material support to ASWJ and transactions between the group and U.S. persons, and freeze any U.S. property it may possess."
