The United States government has designated the Egyptian, Lebanese, and Jordanian branches of the Muslim Brotherhood as terrorist organisations, imposing sanctions and criminal penalties on their members. The move, announced by the Treasury and State departments, follows an executive order and is part of a broader effort to counter violence and destabilisation linked to these groups. While some US allies in the region may welcome the decision, others where the Brotherhood is tolerated could see increased diplomatic tensions. Analysts warn the designations could also affect legal and humanitarian outcomes, including immigration and asylum cases involving Brotherhood members.
