Approximately 1.6 million Muslims gathered in Mecca on Sunday to prepare for the start of the annual Hajj pilgrimage [1].

The gathering represents one of the largest annual human migrations on earth. The Hajj is one of the Five Pillars of Islam and is a mandatory religious duty for Muslims who possess the physical and financial ability to travel [3, 5].

Pilgrims from across the globe arrived in Saudi Arabia to participate in the rites. Reports indicate that more than 1.5 million pilgrims arrived from outside the country [2]. The worshippers were seen circling the Kaaba, the central focal point of the Great Mosque in Mecca [4].

The official start of the pilgrimage followed on Monday [1, 2]. This period involves a series of rituals that symbolize unity, and devotion among the global Muslim community.

Authorities in Saudi Arabia manage the logistics of the massive influx of people to ensure safety and order. The concentration of millions of people in a single city requires extensive infrastructure and coordination to prevent overcrowding and manage health risks during the rituals.
