LONDON – A British Airways flight from London to New York was forced to turn back Wednesday after U.S. authorities refused to allow one of the passengers to land, saying he posed a terrorist threat, the airline said.
Flight BA175 was three hours into its journey to John F. Kennedy International Airport when it was forced to turn back to London’s Heathrow Airport, where the passenger was met by police.
U.S. Transportation Security Administration spokeswoman Yolanda Clark said the passenger was traveling on a French passport.
The TSA said the man was a positive match with an anti-terrorism watchlist.
