The hajj pilgrimage began on Wednesday, with over 1.4 million worshippers facing extreme heat in Mecca, where temperatures could exceed 40°C (104°F). Authorities have implemented enhanced anti-heat measures, including increased shaded areas and a larger medical presence, to prevent a recurrence of last year’s heat-related deaths, which totaled 1,301. Pilgrims, dressed in ihram, will perform rituals such as tawaf around the Kaaba and proceed to Mina, while authorities intensify efforts against unregistered pilgrims using drones and surveillance to manage the massive crowds safely.
