Over 1.3 million Muslim pilgrims have arrived in Mecca for this year’s hajj, which begins amid forecasted temperatures exceeding 40 degrees Celsius (104 degrees Fahrenheit). Saudi authorities have implemented extensive safety measures, including deploying 250,000 officials, increasing shaded areas, and utilizing AI and drones for crowd management, following a deadly heatwave last year that resulted in over 1,300 deaths. Despite the intense heat, pilgrims express joy and fulfillment in their spiritual journey, while a crackdown on illegal entrants aims to ensure safety and order during the pilgrimage.
