Ghaed Kadhim Noon predicted that the number of passengers coming to Najaf in the next few days for Arbaeed ceremonies will be much higher than previous years.
He said the airport has made all the required preparations for the arrival of the pilgrims, the al-Madi Press daily reported.
Arbaeen comes 40 days after Ashura, the martyrdom anniversary of Imam Hussein (AS).
Each year, a huge crowd of Shia pilgrims flock to the Iraqi holy city of Karbala, where the holy shrine of Imam Hussein (AS) is located, to perform mourning rites.
Many pilgrims walk all the way from cities like Baghdad and Najaf to Karbala on Arbaeen.
Last year, around 20 million pilgrims from all over the world gathered in Karbala to attend the mourning ceremonies marking Arbaeen.
