The U.S. Department of State has designated Isma'il Fu'ad Rasul Ahmed, also known as Abdallah Kurdi, as a Specially Designated Global Terrorist. This decision was made under Executive Order 13224 and is aimed at blocking Ahmed's assets because he is a leader of the al-Qa'ida Kurdish Battalions. The order also states that no prior notice was required for Ahmed, even if he is present in the United States, to prevent the transfer of funds. This designation was signed by Secretary of State Michael R. Pompeo and will be published in the Federal Register.
Simple Explanation
The U.S. government has put Isma'il Fu'ad Rasul Ahmed on a special list of people considered to be very dangerous because they think he helps a group linked to bad actions. This means his money is frozen, and he can't move it around.
