Iran's chief of police Brigadier General Ahmad Reza Radan says the runoff presidential election is underway in full security, calm and strength.
Speaking to reporters in Tehran on Friday, Radan hailed the outstanding participation of Iranians in the runoff election to choose the 14th president for four years.
He said all police forces carefully took care of people's votes in the first round of the election last Friday.
The police chief expressed hope that the high turnout of the Iranian nation will lead to an excellent outcome.
He called on people to observe all rules and regulations and remain committed to moral values.
Iranians on Friday headed to the polls in the runoff presidential election, a week after none of the candidates could secure the majority of votes in the snap election.
The final result will be announced on Saturday, although initial figures may arrive sooner.
The runoff follows the June 28 election in which Masoud Pezeshkian and Saeed Jalili emerged as frontrunners, yet neither secured an outright majority.
More than 24 million people participated in the June 28 election.
The election seeks to appoint a successor to President Raeisi, who passed away on May 19 in a tragic helicopter crash.
