At London's Heathrow Airport, Iranians were turned back as they tried to board planes for the United States. The US carriers Pan American World Airways and Trans World Airlines said nearly a dozen Iranians had to leave checkout counters at the airport.
The airlines said the US Immigration Act calls for a $5,000 fine for every Iranian passenger they carry, now that President Carter has imposed his strict sanctions on Iran. Only Iranians with US alien-registration cards are being allowed to travel, a Pan Am official said.
A TWA attendant said he turned away an Iranian woman who was returning to her home in the United States after a week's vacation.
"She was speechless," the attendant said. "She could not believe that she couldn't go home."
