Iranian officials are denying a Canadian newspaper report that the parliament in Tehran is considering a bill that would require non-Muslims to wear colored labels.

The officials say there is no law under consideration that requires colored identification labels for Jews, Christians and Zoroastrians.

On Friday, the National Post newspaper in Canada said the Iranian parliament passed a law Monday that would force non-Muslims to wear colored identification labels.

The Associated Press says it received a copy of the proposed legislation, and that it encourages the wearing of Islamic clothing, but not special attire for religious minorities.

The U.S. State Department and the prime ministers of Canada and Australia expressed concern about the report, and said if true, the measure is abhorrent.
