The U.S. State Department said Saturday it has suspended the issuance of all visitor visas for individuals holding Gaza travel documents while it conducts what it called “a full and thorough review” of recent screening procedures. The freeze, announced by Secretary of State Marco Rubio, applies to standard B1/B2 visas as well as a small number of medical-humanitarian waivers granted in recent days. Department data show the United States has issued more than 3,800 B1/B2 visitor visas to holders of Palestinian Authority travel documents so far this fiscal year, including 640 in May. Officials did not specify how many of those recipients came from the Gaza Strip, nor how long the suspension will last. The move follows online allegations by far-right commentator Laura Loomer that Palestinian refugees from Gaza had entered the United States this month, prompting calls for an investigation from Republican Representatives Chip Roy of Texas and Randy Fine of Florida. Palestinian aid groups condemned the decision, warning it could have a “devastating impact” on civilians seeking urgent medical treatment abroad.
