Pilgrims were trekking en masse in a desert valley near the Saudi holy city of Makkah to perform the third and final day of a symbolic devil-stoning ritual as part of the annual Haj that ends on Sunday.
An estimated 2.3mn Muslims from around the world are attending this year's Haj, Islam's largest gathering. 
Each pilgrim ritually casts 21 pebbles at three walls symbolising the devil inside a multilevel structure known as the Jamarat Bridge in Mina, around 7 kilometres north-east of Makkah.
Large numbers of security force members have been deployed in Mina since the ritual started on Friday to prevent stampedes.
The pilgrims will then head to Makkah to walk seven times around the cube-shaped Kaaba in a rite called the "farewell tawaf" that marks the end of the five-day pilgrimage.
Saudi authorities have said this year's Haj has been free of trouble.
