Saeed Ohadi, who is in the holy city of Makkah, told IQNA that 64000 Iranians have made the pilgrimage trip to perform Hajj.
He added that most of the Iranian Hajjis are content with the services provided by the organization during the Hajj pilgrimage.
Hajj is the annual pilgrimage to Mecca, Saudi Arabia, and the largest mass gathering in the world.
Every able-bodied adult Muslim who can afford to do so is required to perform Hajj at least once in his or her lifetime.
Hajj takes place in the month of Dhu al-Hijja, the last month of the Islamic calendar year.
