Amid Rising Heat, Hajj Becomes Test of Endurance for Pilgrims and Saudi Arabia

The hajj, one of the largest annual human gatherings in the world, begins on Wednesday in Mecca, Saudi Arabia. Amid rising temperatures and logistical challenges, the pilgrimage has increasingly become a test of endurance both for pilgrims and the Saudi government.

Millions of Muslims from around the world travel to the city to take part; Saudi Arabia said 1,475,230 pilgrims from abroad have arrived since Sunday. Last year, the Saudi government said more than 1,300 pilgrims died, many from Egypt. Most of those who perished had been unregistered, Saudi officials said, meaning they had made the trip without the permits that gave them access to heat protections.
