Confusion reigned Sunday at airports in the Middle East and Europe over exactly which citizens from the seven nations subject to President Donald Trump’s travel ban are still permitted to fly to the U.S. Airlines at hubs from Dubai to London Heathrow were grappling with the implications of two court rulings in the U.S. late Saturday that have temporarily blocked the enforcement of parts of Trump’s executive order.
