Crown Prince Mohammed bin Naif bin Abdulaziz, the kingdom's interior minister, oversaw a meeting late Sunday about the disaster, according to the official Saudi Press Agency (SPA). The agency's report did not mention any official response to the rising death toll.
"The crown prince was reassured on the progress of the investigations," the SPA report said. "He directed the committee's members to continue their efforts to find the causes of the accident, praying to Allah Almighty to accept the martyrs and wishing the injured a speedy recovery."
King Salman ordered the investigation into the disaster, the deadliest in the history of the annual pilgrimage. It came after a crane collapse in Mecca earlier that month killed 111 worshippers, and the twin disasters marred the first Hajj overseen by the king since he ascended to the throne at the start of this year.
The Saudi king holds the title of custodian of the two holy mosques, and the monarchy's supervision of the Hajj is a source of great prestige in the Muslim world. Riyadh has rejected a suggestion by Shia power Iran, its main regional rival, to have an independent body take over planning and administer the five-day Hajj, which is required of all able-bodied Muslims once in their lifetime.
Iran has repeatedly blamed the disaster on the Saudi royal family, accusing it of mismanagement and of covering up the real death toll, which Tehran says exceeds 4,700, without providing evidence.
"The lying and hypercritical bodies, which claim to [be promoting] human rights, as well as the Western governments, which sometimes make great fuss over the death of a single person, remained dead silent in this incident in favor of their allied government," Iran's Supreme Leader Ayatollah Ali Khamenei said Monday, according to a transcript on his website.
"If they were sincere, these self-proclaimed advocates of human rights should have demanded accountability, compensation, guarantee for nonrecurrence and punishment for the perpetrators of this catastrophe."
Iran and Saudi Arabia are deeply divided on a host of regional issues and back opposite sides in the wars in Syria and Yemen, where a Saudi-led coalition has been at war with Iran-backed Shia rebels, known as Houthis, since March.
The AP count of the dead from the Mina crush and stampede comes from state media reports and officials' comments from 30 of the over 180 countries that sent citizens to the hajj.
Iran leads all the affected countries, saying it had 465 pilgrims killed. Many of the dead also came from Africa. Mali said it lost 254 people, while Nigeria lost 199, Cameroon lost 76, Niger lost 72, Senegal lost 61, and Ivory Coast and Benin both lost 52.
Others include Egypt with 182, Bangladesh with 137, Indonesia with 126, India with 116, Pakistan with 102, Ethiopia with 47, Chad with 43, Morocco with 36, Algeria with 33, Sudan with 30, Burkina Faso with 22, Tanzania with 20, Somalia with 10, Kenya with eight, Ghana and Turkey with seven, Myanmar and Libya with six, China with four, Afghanistan with two and Jordan and Malaysia with one.
