“The Saudi government must provide us with guarantees about the safety of [Iranian] pilgrims and only under such conditions we will send pilgrims” to Saudi Arabia, Saeed Ohadi said on Sunday.
He added that Iran has an annual Hajj quota of 64,000 pilgrims, whose safety is vital for the country.
The crush of last year occurred after two large masses of pilgrims converged at a crossroads in Mina, near the holy city of Mecca, during the symbolic ceremony of the stoning of Satan in Jamarat on September 24, 2015.
Saudi Arabia claims nearly 770 people were killed in the incident, but Iranian officials say about 4,700 people lost their lives in the tragedy.
The number of the Iranian fatalities is at least 464, exceeding that of other countries.
Saudi Arabia has come under harsh criticism over its handling of the Mina incident.
The tragedy came days after a massive construction crane collapsed into Mecca’s Grand Mosque, killing more than 100 people and leaving over 200 others wounded. According to the figures released by Iran’s Hajj and Pilgrimage Organization, 11 Iranian pilgrims were among the deceased and 32 of the injured were also Iranian nationals.
