Millions of Muslim pilgrims performing the Hajj in Saudi Arabia have thrown stones at three pillars representing the devil, as part of a ritual.
Millions of pilgrims took part in the ritual
New security measures have been added in an effort to control the movement of pilgrims and prevent stampedes that have killed hundreds in the past.
Saturday's ritual coincides with the Muslim festival of Eid al-Adha. The Hajj ends on Monday.
Muslims are obliged to undertake the pilgrimage at least once, if able.
An estimated 30,000 Saudi police and security forces have been deployed to marshal the crowds at this year's Hajj.
On Saturday, pilgrims passed the three pillars in Mina, throwing stones at them.
The pillars stand at the spot where the devil is believed to have appeared before Abraham.
On Thursday, pilgrims from more than 70 countries made the short journey from Mecca to the tented city of Mina five km (three miles) away.

Mina houses the pilgrims as they perform most of the rituals of Hajj, marking the re-enactment of the trials of Abraham.
On Friday, pilgrims took part in a prayer ceremony on Mount Arafat - one of the main events in the annual pilgrimage to Mecca.
The ritual formed the spiritual climax of the Hajj.
Before the pilgrims complete the Hajj they must walk seven times round the Kaaba, a cube-like building in the centre of the city's Great Mosque, in an anti-clockwise direction.
