Muslim pilgrims arrive to circumambulate around the Kaaba, Islam’s holiest shrine, at the Grand mosque in the holy Saudi city of Mecca during the annual hajj pilgrimage, on July 17, 2021. – The annual hajj pilgrimage, one of the five pillars of Islam, started with just 60,000 vaccinated Saudi residents allowed to take part this year because of the pandemic. For the second year in a row, Muslims from abroad have been excluded from the hajj, which drew 2.5 million pilgrims to Saudi Arabia in 2019 before the virus struck. (Photo by Fayez Nureldine / AFP)
