Hajj pilgrimage for millions, on 'most significant day'

As many as three million Muslims have made their way to Saudi Arabia for the annual Hajj pilgrimage.

The pilgrims have been attending prayers at Mount Arafat, a symbolic holy site.

New crowd control measures have been introduced this year, including a light rail system to transport pilgrims to and from the site.
