In victory for moderates, Iranian President Hassan Rouhan wins re-election

Supporters of Iranian President Hassan Rouhani celebrate after he won the presidential election in Tehran, Iran, Saturday, May 20, 2017.

In 2015, he negotiated a landmark nuclear deal that won Iran relief from worldwide sanctions in exchange for limits on its contested nuclear programme.

As for the future of relations between Tehran and Washington, Parsi says "President Rouhani's reelection also creates an opportunity for the Trump administration to chose diplomacy over war with Iran".

"What I would hope, is that Rouhani. use that (new) term to begin a process of dismantling Iran's network of terrorism, dismantling its financing of the terrorist network, dismantling the manning and the logistics and everything that they provide to these destabilising forces that exist in this region", Tillerson said in Riyadh.

The nuclear deal won Iran relief from worldwide sanctions in exchange for limits on its contested nuclear program. He obtained 57.13 percent of the ballots by garnering over 23 million votes.

The election comes as Trump visits Saudi Arabia, the heart of the Sunni branch of Islam.

Besides, no factor could hinder Iran's defense programs, he said, describing the boost of Iran's missile defense systems as a top priority for the Islamic republic.

"We also hope that he restores the rights of Iranians, for freedom of speech, of organisation, so that Iranians can live the life they deserve", Tillerson said.

Rouhani made an apparent dig at Saudi Arabia, saying Iran had demonstrated to its neighbours that "the path to ensuring security is the reinforcement of democracy, not relying on foreign powers".

"I humbly bow my head down to you", Rouhani said to his people in a tweet translated from Farsi.

The two other candidates left in the race, Mostafa Mirsalim, a former culture minister, and Mostafa Hashemitaba, a pro-reform figure who previously ran for president in 2001, each garnered fewer than half a million votes compared to Rouhani's more than 41 million.

Cars honked amid patriotic chants as more and more people filled the streets after dark, completely blocking traffic across wealthier north Tehran.

"In the same way we campaigned for him, we will demand he keeps his promises", said Afshin.

European Union foreign policy chief Federica Mogherini also tweeted her congratulations and vowed to work for greater "engagement, regional peace".

As well as the purple of the Rouhani campaign, many wore the green of the reformist Green Movement, which was harshly suppressed after mass protests in 2009.

Many had thought economic stagnation and unemployment would harm Rouhani's chance at victory.

"I voted for Mr. Rouhani", said Mostafa, a voter in Tehran who spoke to CNN. Iranians flocked to the polls on Friday, with the turnout reaching 73 percent and forcing election officials to extend voting by several hours.

Under the nuclear deal, Iran would reduce its stockpile of low-enriched uranium by 98% and significantly scale back its number of installed centrifuges.
