"Iran's Civil Aviation Organization has not received any report from the German officials on sanctions against Mahan Air and the German government's spokesman has said about the claim by Bild that he could not comment," Reza Jafarzadeh told the Fars News Agency.
The airline carries out six flights between Tehran and Germany per week: four flights from Duesseldorf and two more from Munich.
Mahan Air was sanctioned by the US Treasury Department in October 2011. According to the US Treasury, the airline routinely transports fighters and equipment to Syria in order to support the government of Syrian President Bashar Assad.
On Friday, the Bild newspaper reported that the German government was going to ban the airline from using national airports starting from January 2019. The decision was reportedly made after intensive discussions and followed the US intelligence services’ claims that German cooperation with Mahan Air would threaten the security of US citizens in German airports.
