"Political letters are commonplace and it is natural for the president of a country to write to the leader of another country, and this has been neither the first nor the last such letter in Iran's political history," Kharrazi told FNA in Tehran on Tuesday.
He underlined Iran and Ayatollah Khamenei's influential role in the region and the Muslim world, and said, "They need Iran's special position in the world, the Middle-East region and the Muslim world as establishment of regional security and security belt is not possible without Iran."
Wall Street Journal reported earlier this month that Obama wrote a letter to Ayatollah Khamenei in October. "In it, Obama has reportedly talked about their shared interests fighting ISIL terrorists in Iraq and Syria," the WSJ report said.
No Iranian official has confirmed the letter by now but today Iranian Parliament Speaker Ali Larijani in his remarks at the state-run TV indicated that the US president has written a letter to Ayatollah Khamenei, although he did not mention if he meant an earlier letter or what the WSJ report claimed.
Blasting the United States' hypocritical attitude in and outside the nuclear talks with Iran, Larijani questioned why Obama "uses bullying words against Iran when he speaks to the media, but picks up a very friendly and kindly tone when he writes a letter to the Supreme Leader".
