In pictures: Saudi security personnel on alert as pilgrims pour into Makkah for Haj

Makkah, Saudi Arabia – More than 1.5 million Muslim pilgrims have begun arriving in Mina, a vast tent city near Makkah, for the annual Haj pilgrimage. The white-robed worshippers, arriving by bus and on foot, are completing rituals after performing the tawaf, the circumambulation of the Kaaba.

Saudi security forces are on high alert, with personnel visible in and around the Grand Mosque and the pilgrimage sites. Military parades and demonstrations by security forces have been held in preparation, showcasing their readiness to manage the massive influx of worshippers and ensure security during the rites.

This year's pilgrimage takes place against a backdrop of heightened security concerns. It follows a series of attacks targeting Saudi Arabia and its neighboring Gulf countries. The presence of pilgrims from across the world, including Iran, underscores the global significance of the Haj and the security measures in place to protect attendees.

The images capture the scale of the event, with pilgrims filling the encampment in Mina and security officers directing crowds to prevent overcrowding, particularly at the Grand Mosque. The sun setting over the plain of Arafat signifies the spiritual journey undertaken by millions of Muslims converging in the holy city.
