The Arbaeen mourning ceremony is one of the largest religious gatherings in the world.
It marks the 40th day after Ashura, the martyrdom anniversary of the grandson of Prophet Mohammad (PBUH), Imam Hussein (AS). The day of Arbaeen falls on September 17 this year.
Each year, a huge crowd of Shias flock to Karbala, where the holy shrine of Imam Hussein (AS) is located, to perform mourning rites.
The pilgrims, mainly from Iraq and Iran, travel long routes on foot to the holy city.
Some officials have predicted that around five million Iranians will travel to Iraq to take part in the Arbaeen procession this year.
