See the hajj diminished, distanced by the coronavirus

Pilgrims visiting Mecca this year are physically distancing standing apart and moving in small groups of 20 to limit exposure andpotential transmission of the coronavirus during the annual hajj in the holy city of Mecca, Saudi Arabia.

As few as 1,000 people already residing in Saudi Arabia were selected to take part in the pilgrimage this year.

The pilgrims arerequired to be between the ages of 20 and 50, with no terminal illnesses and showing no symptoms of the virus. Preference isgiven to those who have not performed the hajj before.
