In a tragic turn of events, at least 68 Indians are reportedly among 922 pilgrims from various countries who have died during this year’s Haj pilgrimage in Makkah, Saudi Arabia, due to intense heat temperatures reaching 51.8 degrees Celsius.

The deaths were attributed to natural causes, old age, and intense weather conditions, the diplomat told Agence France-Presse (AFP) on the condition of anonymity on Wednesday, June 19.

The highest number of casualties came from Egypt, at least 600, a increase from the previous day’s 300.
