Hajj Stampede Kills At Least 717

A horrific stampede killed at least 717 pilgrims and injured hundreds more Thursday on the outskirts of the holy city of Mecca in Saudi Arabia, the deadliest tragedy to strike the annual hajj pilgrimage in more than two decades.

At least 863 pilgrims were injured in the crush, said the Saudi civil defense directorate, which provided the death toll. The tragedy struck as Muslims around the world marked the start of the Eid al-Adha holiday.
