For the first time in more than 30 years the President of the United States has spoken with Iran's leadership. Barack Obama announced he believes the two sides can reach a deal regarding the future of the Islamic Republic's nuclear program.

From the White House Friday afternoon, Obama said he just got off the phone with Iranian President Hassan Rouhani and discussed “our ongoing efforts to reach an agreement over Iran's nuclear program.”

“I believe we can reach a comprehensive solution,” Obama said, adding that he has asked US Secretary of State John Kerry to continue pursuing a deal with Iran that would prohibit Tehran from pursuing the development of nuclear weapons.

“I do believe that there is a basis for a resolution,” Obama said.

“Rouhani has indicated that Iran will never develop nuclear weapons,” Obama said, hailing that sentiment as a “major step forward in a new relationship between the United States and the Islamic Republican of Iran.”

Obama said his conversation with Rouhani earlier that day marked the first communication between an American and Iranian president since 1979 and “underscores the deep mistrust between our countries” that he hopes to now bury.

'Thank you, Khodahafez'

After a historic phone conversation with Barack Obama, President Rouhani has left the United States tweeting his reaction to the breakthrough in diplomatic relations between the two countries, which itself is an unusual development.

“In regards to the nuclear issue, with political will, there is a way to rapidly solve the matter,” Rouhani tweeted the US President.

Rouhani stressed that the next round of negotiations with the P5+1 should prove fruitful.

“We're hopeful about what we will see from P5+1 and your government in particular in coming weeks and months,” the tweet read adding that “I express my gratitude for your hospitality and your phone call,” Iranian’s leader said at the end of the conversation “Have a good day Mr President.”

The US President, according to Rouhani’s Tweets, expressed his respect for the Iranian people.

“I express my respect for you and people of Iran. I'm convinced that relations between Iran and US will greatly affect region. If we can make progress on nuclear file, other issues such as Syria will certainly be positively affected,” Obama reportedly told Rouhani during the phone call.

At the end of the call Obama wished Rouhani farewell saying, “Thank you, Khodahafez,” a common parting phrase in the Persian language, while Rouhani wished Obama does not get caught in horrendous traffic jam in New York City.

Witnesses say the two leaders spoke for about 10 minutes immediately after the conclusion of Rouhani's last scheduled meeting, just as he was about to leave the UN General Assembly gathering. The presidents spoke in English without a translator, an Iranian witness told NBC’s Robert Windrem, adding that Rouhani was a bit “shocked” to receive a call from Obama.

On the sidelines of the UN General Assembly on Thursday, US Secretary of State John Kerry sat next to his Iranian counterpart Mahammad-Javad Zarif for the first time as well, in the company of the EU’s chief diplomat Catherine Ashton and delegates from the five permanent members of the Security Council plus Germany.



The participants agreed to "go forward with an ambitious timeframe," according to Ashton, and will meet in Geneva on October 15-16.
