Story highlights U.S. officials say religion didn't play a part in the decision to stop the family

Family says they have received no explanation for being barred

Norwegian Airlines says it "fully complies with requests from the border controls of each country"

(CNN) A Muslim man in London says his family was barred because of their religion from boarding a plane bound for Los Angeles, where they planned to visit Disneyland with their children.

On December 15, the extended family waited at the gate. Their bags were on the plane. The family included Mohammad Tariq Mahmood with two of his children; his brother Zahid and sister-in-law Sadaf, with five of their children; and two nieces who were accompanying them.

While they waited to board the plane, Mohammad Mahmood was called on the intercom and told that at least some of the family would not be allowed to board. They were not given a reason for the ban, according to Mahmood. Their bags were removed from the plane, and they were ordered to return all the duty-free goods they had purchased, and then escorted from the airport.

A U.S. official on Wednesday told CNN that not all family members were prevented from traveling, but did not specify who would have been permitted to travel.

A British MP alerted the media to the story Wednesday after speaking with Mahmood.
