Iran's civil aviation organization says it has asked the United States to resume direct flights between the two countries that were suspended more than 25 years ago.

Iranian civil aviation officials say they sent a letter to their U.S. counterparts on Wednesday.

They say President Mahmoud Ahmadinejad decided to propose the resumption in response to a request from Iranians living in the United States and Canada. The request was made in September when Mr. Ahmadinejad attended a U.N. session in New York.

There was no immediate U.S. response.

Iranian airliners have been barred from the United States since Washington broke ties with Tehran, following the 1979 Islamic revolution.
