US President Barack Obama has reportedly sent his second direct message to Iran's leading authority, the Leader of the Islamic Republic Ayatollah Ali Khamenei, Press TV reported.
Tabnak, a semi-official Iranian news service, on Wednesday said the country's most prominent political figure has received a second letter, but did not mention the exact date the correspondence had reached Tehran.
"The first letter was dispatched in Ordibehesht, before the elections," Tabnak said referring to the second solar month of the Persian calendar corresponding to 21 April to 21 May.
According to the report, Obama's first letter was not left without an answer.
"The leader at the time replied to the letter by providing argumentation," the report added without revealing the contents of the letter.
Obama, whose campaign for the White House included a pledge to open talks with Iran, struggled to make a clean break from the Bush administration by offering an 'extended hand' to Tehran after his election.
In his first sit-down interview in January, the US president said, "If countries like Iran are willing to unclench their fist, they will find an extended hand from us."
Tehran and Washington have had no diplomatic relations for nearly three decades. The two countries severed all ties in 1980 in the aftermath of the Islamic Revolution and the US embassy takeover by Iranian revolutionary students.
