A US couple who died during the Hajj pilgrimage in Saudi Arabia were walking for over two hours in scorching temperatures before they succumbed to heat stroke, their daughter told the BBC.

Alhaji Alieu Dausy Wurie, 71, and Haja Isatu Wurie, 65, of Bowie, Maryland, were among an estimated 1,300 people who died during the annual pilgrimage to Saudi Arabia.

Temperatures during this year’s gathering exceeded 122F (50C) at times.
