Recently, there has been a significant increase in Turkish, Azerbaijani, and Georgian pilgrims traveling through Iran to participate in the Arbaeen pilgrimage in Iraq. Over 6,000 pilgrims entered Iran via the Bazargan border crossing, with a single-day record of 2,401 arrivals. The pilgrimage, commemorating the martyrdom of Imam Hussein (AS), is the largest religious gathering globally, drawing millions. Factors for the surge include improved transportation, heightened awareness, and eased travel restrictions. Local communities are preparing to support the influx with accommodations, food, and transportation. This year’s diverse participation enhances the sense of unity and shared values among Muslims worldwide.
