Watch: Millions face oppressive Saudi Arabia heat wave for religious pilgrimage
About 1.8 million Muslims set out in a heat wave for the Hajj, a religious pilgrimage that religious texts require "able bodied" Muslims to perform at least once. With temperatures hitting 117-120 degrees in Mecca, over 1,300 people have died in the heat so far.
