Saudi Arabia's Hajj overhaul includes policy updates and high-tech safety measures following last year's heat deaths.

ARAFAT, Saudi Arabia (AP) — Tens of thousands of Muslim pilgrims clambered up rocks and nestled between boulders on Thursday as they embarked on a day of worship under a scorching sun at the Hajj in Saudi Arabia. Braving the heat and uneven surfaces, they scaled Mount Arafat to perform a key ritual of the annual Islamic pilgrimage.

Saudi Arabia has barred more than 269,000 people without permits for the annual Hajj pilgrimage from entering Mecca this week, authorities said, as the world's largest annual gathering of people has officially begun.

Saudi Arabia has announced drastic changes for the 2025 Hajj pilgrimage that begins today, including new rules prohibiting children from accompanying pilgrims, and prioritizing pilgrims traveling for the first time.

Millions have made the annual pilgrimage to Mecca. The kingdom faces scrutiny over safety after more than 1,300 people died last year.
