Hamid Mohammadi, a deputy of Iran’s Hajj and Pilgrimage Organization, said that in towns where there are no travel agencies, temporary offices have been set up to receive the documents.
He said more than 80,000 individuals have so far registered their name for the pilgrimage, advising those who want to make the pilgrimage not to delay their registration.
Arbaeen, which is one of the largest religious gatherings in the world, comes 40 days after Ashura, the martyrdom anniversary of the third Shia Imam, Imam Hussein (AS).
Each year, a huge crowd of Shias flock to Karbala, where the holy shrine of Imam Hussein (AS) is located, to perform mourning rites.
In the past few years, around 20 million pilgrims from all over the world, including Iran, gathered in Karbala to attend the mourning ceremonies marking Arbaeen.
This year, Arbaeen falls on Sunday, November 20.
