TABNAK, Aug, 21: The Iranian official also called for providing probable health care for pilgrims injured in the bus accident.
At least 28 pilgrims from Pakistan have been killed and 23 injured after their bus overturned in central Iran.
The accident took place as 53 passengers were on board and the bus crashed en route to the holy city of Karbala in Iraq for the Arbaeen pilgrimage.
Millions of Shia Muslims are currently taking part in the Arbaeen pilgrimage and they typically drive through Iran to reach their destination.
The Arbaeen commemoration marks the 40th day of mourning for Imam Hussein, the grandson of the Prophet Muhammad and son of Imam Ali, who was killed in 680 AD on the plains of Karbala.
Many pilgrims opt to walk 80km (50 miles) from the nearby city of Najaf, where Imam Ali is buried, to Karbala.
Last year, some 22 million pilgrims attended the commemoration in Karbala.
