At least 550 pilgrims have died during the hajj, underscoring the gruelling nature of the pilgrimage which again unfolded in scorching temperatures this year.
At least 60 Jordanians have died, the diplomats said, up from an official tally of 41 given earlier on Tuesday by Amman.
The new deaths bring the total reported so far by multiple countries to 577, according to an AFP tally.
The diplomats said the total at the morgue in Al-Muaisem, one of the biggest in Mecca, was 550.
Temperatures hit 51.8Cat the Grand Mosque in Mecca on Monday, the Saudi national meteorology centre said.
About 1.8 million pilgrims took part in the hajj this year, 1.6 million of them from abroad, according to Saudi authorities.
Earlier this month, Saudi officials said they had cleared hundreds of thousands of unregistered pilgrims from Mecca before the hajj. »
