MECCA. — At least 717 people have been killed in a stampede at the annual Hajj pilgrimage, Saudi Arabia’s civil defence directorate said, as the death toll continued to rise.

The directorate said at least 863 other pilgrims were injured in yesterday’s stampede, which took place in Mina, on the outskirts of the holy city of Mecca.

The injured were evacuated to four different hospitals in the Mina region, according to a civil defence spokesman.

Saudi Arabia’s crown prince, Prince Mohamed bin Nayef, ordered a probe into how the tragedy had occurred.

Nayef, who chairs the Saudi Hajj committee, ordered the probe during a meeting with senior officials responsible for the pilgrimage in Mina, where the stampede took place.

The findings of the investigation will be submitted to King Salman, “who will take appropriate measures” in response, the Saudi Press agency said.

Mina is where pilgrims carry out a symbolic stoning of the devil by throwing pebbles against three stone walls.

It also houses more than 160 000 tents where pilgrims spend the night during the pilgrimage.

Al Jazeera’s Basma Atassi, reporting from Mina, said the incident took place in a street between pilgrim camps.

“The street where it happened is named Street 204. This stampede did not happen at the site of the ‘stoning of the devil’ ritual, which was happening today.

“During and after the stampede, the pilgrims continued to flock into Mina to perform the devil stoning ritual.”

Amateur video shared on social media showed a horrific scene, with scores of bodies — the men dressed in the simple terry cloth garments worn during Hajj — lying alongside crushed wheelchairs and water bottles.

Saudi authorities take extensive precautions to ensure the security of the Hajj and the safety of pilgrims. But tragedies are not uncommon.

In 2006, more than 360 pilgrims were killed in a stampede, also in Mina.

The day before the 2006 Hajj began, an eight-story building being used as a hostel near the Grand Mosque in Mecca collapsed, killing at least 73 people.

Two years earlier, a crush at Mina killed 244 and injured hundreds on the final day of the pilgrimage.

And, in 2001, a stampede at Mina killed 35 people. The worst hajj-related tragedy, which happened in 1990, killed 1,426 pilgrims in a stampede in an overcrowded pedestrian tunnel leading to holy sites in Mecca. — Al Jazeera.
