Airport authorities in Abadan in the southwestern province of Khuzestan had to cancel flights on Friday due to poor visibility as a result of increased dust in the air, according to IRNA.
An official at Abadan's Ayatollah Jami International Airport confirmed that a number of flights have been cancelled due to dust pollution.
In addition to flights cancellation, dust storms, overwhelming much of western and southwestern Iran, have also prompted health warnings and resulted in closed schools and offices in some areas.
Health officials have warned residents with heart and respiratory problems to stay at home.
The storms began last Thursday and the authorities expect the situation to improve in the coming days.
The dust originates from Iraqi and Syrian deserts. Iraq has long suffered periodic, blinding sandstorms, but several years of drought have aggravated the situation there.
