Iran reports it has set up 60,000 polling stations across the country and 290 in over 96 countries abroad. More than 50 million Iranians are eligible to vote, among them 1.6 million eligible for the first time.
Iran's supreme leader, Ayatollah Ali Khamenei, cast his vote earlier today and delivered a short message to the Iranian people:
"The dear Iranian people should enter the scene of elections with fervor and motivation, and [they should] know that the destiny of the country and prosperity of the nation depend on their presence and the choice they make. The views of enemies have never had any significance for the Iranian people, and the [Iranian] nation itself has always made decisions about what it needs and what is in the interest of the country, and has made and will make its choice on that basis."
Here's a round up of what the candidates said when casting their votes:
Saeed Jalili: "Any candidate that people choose and comes out of ballot box, should be respected by everyone."
Ali Akbar Velayati: "I request the entire Iranian nation to come to the ballot boxes enthusiastically and elect their favourite candidate since people's participation in the presidential and (city and village) councils elections is a reaffirmation of their support for the Islamic Republic ruling system."
Mohsen Rezaei: "We make our own destiny [by voting] and this is why we should protect it and participate [in the election actively]."
Hassan Rouhani: "Tomorrow is the day of victory for people of Iran... If people come and vote then it's a victory for us as a country because enemies wanted them to boycott the election."
Mohammad Gharazi: "It's up to people to decide and whatever they say and whatever the interior ministry and the Guardian Council announces, I will accept. I completely trust the Guardian Council [which monitors the voting process]."
Mohammad-Bagher Ghalibaf: "I want to bring fundamental change to my country by focusing on development and justice.... People's choice will be respected by me, too."
