Hajj pilgrims 'stone the devil' as Muslims mark Eid al-Adha

Pilgrims perform the last major ritual of the hajj, the "stoning of the devil", in western Saudi Arabia on Sunday, as Muslims the world over celebrate the Eid al-Adha holiday.

Beginning at dawn, the 1.8 million Muslims undertaking the pilgrimage this year will throw seven stones at each of three concrete walls symbolising the devil in the Mina valley, located outside Mecca, the holiest city in Islam.
