British officials are calling for action after U.S. agents at London’s Gatwick Airport barred a British Muslim family from traveling to Disneyland. They were not allowed to board their flight to Los Angeles on Dec. 15. The family of 11 had already been granted travel authorization ahead of their scheduled flight, The Guardian reports. U.S. Department of Homeland Security officials allegedly provided no explanation for the action. British officials said Prime Minister David Cameron would look into the case.
