Earlier this week, US President Donald Trump threatened Iran bombings if it refuses a deal.
"We have stated our position - we are in favor of the diplomatic path and negotiations, but via mediators. Of course, it should be emphasized that not a single round of such talks has been held yet," Araghchi said in a statement published by the Iranian Foreign Ministry on Telegram.
The minister also said that the US "can only dream" of a deal with Iran similar to its 2003 with Libya, which back then agreed to give up its ambition to obtain weapons of mass destruction in exchange for sanctions relief.
