TEMPO.CO, Cairo - Every year, millions of Muslims converge on the Saudi Arabia holy cities of Mecca and Medina for the annual hajj pilgrimage, with the massive ceremonies representing a major security and logistical challenge for the kingdom's authorities.
On occasion, the hajj and events surrounding it have been marred by accidents and tragedies, such as Thursday's stampede near Mecca that killed at least 310 people.
Here's a look at some deadly hajj-related incidents:
* 2015: At least 310 people are killed and hundreds injured in a stampede in Mina, on the outskirts of the holy city of Mecca. In the lead-up to hajj, 111 people are killed and nearly 400 injured when a crane collapses in bad weather, crashing onto the Grand Mosque in Mecca, Islam's holiest site.
* 2006: More than 360 pilgrims are killed in a stampede at the desert plain of Mina, near Mecca, where pilgrims carry out a symbolic stoning of the devil by throwing pebbles against three stone walls. The day before the hajj began, an eight-story building being used as a hostel near the Grand Mosque in Mecca collapsed, killing at least 73 people.
* 2004: A crush of pilgrims at Mina kills 244 pilgrims and injures hundreds on the final day of the hajj ceremonies.
* 2001: A stampede at Mina during the final day of the pilgrimage ceremonies kills 35 hajj pilgrims.
