The United States announced new targeted sanctions on Friday against three individuals, including one in Puntland state in Somalia believed to be providing support to Islamic State terrorists.

Mohamed Mire Ali Yusuf (Mire Ali) was listed among Specially Designated Global Terrorists, a status assigned by the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) for “assisting in, sponsoring, or providing financial, material, or technological support for, or financial or other services to or in support of, ISIS.”

Mire Ali owns or controls the Liibaan Trading and Al-Mutafaq Commercial Company, both of which are located in downtown Bosaso, a coastal Puntland city on the Gulf of Aden. U.S. officials say he was the sole owner of Liibaan, a livestock trading business that served as a front for Abdulqadir Mumin. Mumin has been under U.S. targeted sanctions for Islamic State affiliation since August 2016.

Mire Ali was an ISIS-aligned financial operative who provided funds to Mumin, the U.S. Treasury said in its statement. As of late 2016, Al-Mutafaq Commercial Company also was run by Mire Ali.

The decision is part of the stepped-up American effort to rein in Islamic State activities across the globe. Also announced Friday were new sanctions against Abdulpatta Escalon Abubakar, who was investigated for transferring funds to Islamic State in the Philippines and was detained last September. Yunus Emre Sakarya and the Profesyoneller Elektronik firm in Turkey were placed under sanctions, primarily for an alleged role in assisting Islamic State in acquiring drone equipment.
