The road between Najaf and Karbala has been the scene of one of the greatest religious rituals in the world.
During the days leading to Arbaeen, millions of pilgrims from Iraq and other countries go from Najaf to Karbala on foot.
Arbaeen falls on Thursday, November 9, this year.
It 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. Many of them also visit Imam Ali’s (AS) holy shrine in Najaf.
In the past few years, around 20 million pilgrims from all over the world took part in the mourning ceremonies in the Iraqi holy cities marking Arbaeen.
