 Israel prohibits its citizens from visiting enemy nations without permission, a travel restriction which, in 2015, included Syria, Iraq, Iran, Lebanon, Yemen, and Saudi Arabia.The Adalah Legal Center claims this disproportionately discriminates against Arab-Israeli citizens, and that authorities did not detain Jewish Israelis upon return from trips to unauthorized countries as they did with Arab Israelis.The Israel Airports Authority has also been criticised for racial profiling of Arab citizens.
