Iranian planes are getting fuel at airports around the world, Foreign Ministry spokesman Ramin Mehmanparast said on Tuesday, denying reports that some countries were refusing supplies due to sanctions.
"No such limitation has been imposed," he told a news conference.
On Monday, the secretary of the Iranian Airlines Union was quoted on Iran's ISNA news agency as saying Iranian planes had been refused fuel at airports in Britain, Germany and UAE because of U.S. sanctions.
The German Transport Ministry said there was no ban on refuelling Iranian flights in Germany and a British government source said London was not aware of any cut to supplies and that any such a decision would be up to private companies.
A source in the UAE familiar with the issue said a private company there had refused to refuel an Iranian plane, but the UAE had imposed no ban of its own.
