President Hassan Rouhani made the remark in his speech to the 70th session of the UN General Assembly in New York on Monday.
He said the feelings of millions of Muslims hurt by the incident amounts to spiritual loss which cannot be compensated for simply by material means, Press TV reported.
“The public opinion demands that Saudi authorities discharge, without delay, their international responsibility in providing immediate consular access for the quick identification and returning of the bodies [of the diseased],” said the president.
“It is also required that the necessary conditions be provided for [conducting] an independent and precise inquiry into the causes of the [Mina] disaster and [working out] methods for preventing a repeat of that in the future,” President Rouhani added.
The number of Iranian pilgrims killed in the recent tragedy in Saudi Arabia’s Mina has increased to 226 with around 250 more still unaccounted for.
Iran’s Hajj and Pilgrimage Organization puts the total number of pilgrims killed from various Islamic countries in the incident at more than 2,000.
