Millions of Shiite Muslims congregated in Karbala, Iraq, for the Arbaeen pilgrimage—one of the world’s largest annual religious gatherings.
This spiritual event marks the 40th day after the martyrdom of Imam Hussein, the Prophet Muhammad’s grandson, and draws followers from across the globe.
At least four million people participated in this year’s pilgrimage, according to Iraqi authorities.
Other reports estimate that the total number of pilgrims ranged between 22 million and 25 million, marking a notable increase from previous years.
Many pilgrims walked long distances despite intense heat—sometimes surpassing 52°C—setting out from cities like Najaf and Baghdad.
The pilgrimage is a deeply spiritual effort, with some walking nearly 90 kilometers over several days.
Volunteers played a vital role, operating thousands of mawkibs—tents offering free food, drinks, shelter, and medical help along the pilgrimage paths.
The Iranian Red Crescent deployed approximately 8,000 volunteers, supported by 23 helicopters, 150 emergency vehicles, and numerous medical facilities.
Iraqi officials also managed security with over 52,000 personnel to ensure pilgrims’ safety.
Arbaeen is a momentous occasion in Shia Islam, honoring Imam Hussein’s martyrdom and symbolizing values of justice, sacrifice, and resistance against tyranny.
It brings together believers in mass homage and mourning.
