The hajj claimed the lives of over 550 pilgrims, highlighting the challenging nature of the pilgrimage, which once again took place in extreme heat this year.
Of the deceased, at least 323 were Egyptian, with most of them succumbing to heat-related illnesses.
The number of Jordanian fatalities also rose, with diplomats reporting at least 60 deaths, an increase from the previous official count of 41 announced by Amman on Tuesday.
The latest fatalities bring the total reported by various countries to 577, according to an AFP count.
The diplomats told AFP that there were 550 bodies at the Al-Muaisem morgue, which is one of the largest in Mecca.
The hajj, one of the five pillars of Islam, is obligatory for all Muslims who are financially able to undertake it at least once.
A Saudi study published last month indicated that climate change is increasingly impacting the pilgrimage. The study stated that temperatures in the area where rituals are performed rise by 0.4 degrees Celsius (0.72 degrees Fahrenheit) every decade.
According to the Saudi National Meteorology Centre, the temperature at the Grand Mosque in Mecca reached 51.8 degrees Celsius (125 Fahrenheit) on Monday.
