Iran has announced the number of its citizens who died in the Hajj stampede is now 464, nearly double the previous figure.
Iranian authorities have said there is no longer any hope of finding any of the country's missing pilgrims alive.
The announcement is likely to place more pressure on Saudi Arabia, after Iran vowed to take international action against the Gulf state's rulers for their handling of the disaster.
Iran's supreme leader Ayatollah Ali Khamenei has also called on Saudi Arabia to apologise.
According to Saudi officials, at least 769 people died in the crush last week.
Saudi Arabia's most senior Islamic cleric has claimed Saudi authorities were not at fault because "fate and destiny are inevitable".
