Some 2 million Muslim pilgrims officially began the annual Hajj pilgrimage on Monday, making their way out of Mecca after circling Islam's holiest site, the Kaaba.

A Tokyo Olympic drone display, a memorial for Haiti's slain president and the hajj pilgrimage round out some of this week's most stunning images.

Roughly 2 million Muslims were expected to go on Hajj this year.
