Khamenei accused Riyadh of “a blame game”, after the Saudi foreign minister said Iran was playing politics with tragedy following a stampede that killed 769 pilgrims at the hajj, AFP reported.
About 400 protesters later chanted “Death to the treacherous House of Saud” outside the Saudi embassy in Tehran.
At least 144 Iranians died in the crush — the highest confirmed toll among foreign nationalities. Tehran says 323 Iranians are missing.
Saudi Foreign Minister Adel al-Jubeir, also in New York for the UN General Assembly, said the Iranians “should know better than to play politics with a tragedy that has befallen people who were performing their most sacred religious duty.”
Saudi King Salman, whose official title is “Custodian of the Two Holy Mosques” in Mecca and Medina, ordered “a revision” of how the hajj is organised, and a formal Saudi inquiry is under way into the stampede.
It was the worst disaster to strike the annual pilgrimage in a quarter-century.
“We will reveal the facts when they emerge. And we will not hold anything back,” Jubeir said, adding the kingdom has a long history of devoting “tremendous resources” to ensuring a successful pilgrimage.
“I would hope Iranian leaders would be more sensible and more thoughtful with regards to those who perished in this tragedy, and wait until we see the results of the investigation.”
– Yemen, Syria tensions –
Relations between Shiite Iran and Sunni-dominated Saudi Arabia were already severely strained by conflicts in Yemen and Syria, and an international agreement on Iran’s nuclear programme.
It is also not the first time Iranian pilgrims have been killed in Saudi Arabia. In 1987 Saudi security forces suppressed an unauthorised protest by Iranian pilgrims. An official toll gave the death toll as more than 400, including 275 Iranians.
Iran has demanded that affected countries have a role in the stampede investigation, and the running of the hajj “must be handed over to Islamic states.
Such suggestions are “frankly ridiculous”, columnist Rasheed Abou-Alsamh wrote in Sunday’s Arab News, an English-language Saudi daily.
He said criticism of the kingdom’s hajj organisation is part of a “concerted campaign of defamation against Saudi Arabia by its enemies”.
The Saudi Press Agency over the weekend started a Twitter account, @spa_persian, to transmit official information in the Iranian language Farsi.
Senior Saudi officials suggested the pilgrims were at fault for not following instructions.
The interior ministry has said it assigned 100,000 police to secure the hajj and manage crowds at the event, which drew almost two million faithful.
Hundreds of thousands of pilgrims were converging on a five-story structure known as Jamarat Bridge to perform the stoning ritual when the stampede happened nearby.
The stampede was the second tragedy to cast a pall over this year’s hajj.
A massive construction crane collapsed on Mecca’s Grand Mosque several days before and killed 109 people, many of them pilgrims.
For years, the hajj was marred by stampedes and fires, but it had been largely incident-free for almost a decade after safety improvements and billions of dollars’ worth of infrastructure investment.
