Over 2.1 million pilgrims have passed through the Mehran border crossing in Iran during the Arbaeen season, marking a significant flow of travelers. The Mehran crossing serves as a major western gateway for pilgrims returning from Iraq after commemorating Arbaeen. Iranian authorities report handling heavy traffic volumes as pilgrims complete their journeys. This year’s numbers demonstrate the continued importance of the Arbaeen pilgrimage for Shia Muslims. The influx highlights the logistical efforts required to facilitate the safe and orderly passage of such large crowds. The IRNA news agency reports that traffic remains substantial at the border. This year's Arbaeen observance draws millions from around the world to the holy city of Karbala in Iraq.
