On 1 November, OFAC announced action against the Islamic State in Somalia (ISIS-Somalia), its first designations against this affiliate of ISIS. This follows the recent designations of al-Shabaab financial facilitators and weapons smugglers, further targeting a network of weapons traffickers, their associates, and an affiliated business that have facilitated weapons transfers to multiple terrorist groups. Several of the individuals designated have specifically sold weapons to or were active al-Shabaab members. The individuals and entity designated are critical nodes for a weapons trafficking network that is closely integrated with ISIS-Somalia. These networks operate primarily between Yemen and Somalia and have strong ties to al-Qa’ida in the Arabian Peninsula (AQAP) and al-Shabaab. OFAC also designated a vital supporter of ISIS in Brazil, who has attempted to serve as a liaison for the terrorist group.
