MINA, Saudi Arabia (AP) — As hundreds of thousands of Muslim pilgrims walked in the footsteps of the prophets beneath a sweltering sun, contracted cleaners in lime-green jumpsuits held out matching plastic bags to collect their empty water bottles.

It takes tens of thousands of cleaners, security personnel, medics and others to make the annual Hajj pilgrimage possible for 1.8 million faithful from around the world. As the Hajj concludes on Friday, the workers will begin a massive, weeklong cleanup effort.
