The Supreme Leader of Iran Ayatollah Ali Khamenei has sent a secret letter to the White House, in response to US President Barack Obama's correspondence aimed at improving relations between the two countries, The Wall Street Journal reports, according to Sputnik.

Khamenei's response to Obama's letter, which raised the possibility of cooperation between the United States and Iran in fighting against Islamic State (IS) militants, was "respectful" but "noncommittal," the Wall Street Journal said, citing an Iranian diplomat.

According to the publication, Khamenei had sent another letter to Obama, outlining abuses that the United States committed against the Iranian people over the last 60 years. The letter was received by Obama in 2009, according to a White House official cited by the Wall Street Journal.

Neither the White House, nor the Iranian government has officially confirmed any correspondence between Iran's supreme leader and the US president.

The United States has been part of the ongoing talks between Iran and the P5+1 group on the controversial Iranian nuclear program, which the West suspects to be a cover-up for the development of nuclear weapons.

The UN Security Council, the United States, the European Union, and a number of other countries have imposed sanctions on Iran over its nuclear development, which Tehran insists is exclusively for peaceful purposes.
