CNN  — 

A stampede during one of the last rituals of the Hajj – the annual Islamic pilgrimage to Mecca – has killed more than 700 people and injured nearly 900 others in Saudi Arabia.

The stampede occurred Thursday morning during the ritual known as “stoning the devil” in a tent city in Mina, about two miles from the holy site in Mecca, Islam’s holiest city.
