AFP has reported that the death toll from this year’s hajj has exceeded 1,000.
More than half of the death are unregistered worshippers who performed the pilgrimage in extreme heat in Saudi Arabia.
The new deaths reported Thursday included 58 from Egypt, according to an Arab diplomat who provided a breakdown showing that of 658 Egyptians who passed away, 630 were unregistered pilgrims.
All told, around 10 countries have reported 1,081 deaths during the annual pilgrimage, one of the five pillars of Islam which all Muslims with the means must complete at least once.
The figures have come via official statements or from diplomats working on their countries’ responses.
The hajj, whose timing is determined by the lunar Islamic calendar, fell again this year during the oven-like Saudi summer.
The National Meteorological Centre reported a high of 51.8 degrees Celsius (125 Fahrenheit) this week at the Grand Mosque in Mecca.
According to a Saudi study published last month, temperatures in the area are rising 0.4 degrees Celsius each decade.
Each year tens of thousands of pilgrims attempt to perform the hajj through irregular channels as they cannot afford the often costly official permits.
Saudi authorities reported clearing hundreds of thousands of unregistered pilgrims from Mecca this month, but it appears many still participated in the main rites which began last Friday.
This group was more vulnerable to the heat because, without official permits, they could not access air-conditioned spaces provided by Saudi authorities for the 1.8 million authorised pilgrims to cool down after hours of walking and praying outside.
“People were tired after being chased by security forces before Arafat day. They were exhausted,” one Arab diplomat told AFP on Thursday, referring to Saturday’s day-long outdoor prayers that marked the hajj’s climax.
The diplomat said the main cause of death among Egyptian pilgrims was the heat, which triggered complications related to high blood pressure and other issues.
