TEHRAN: Iranian President Hassan Rouhani said that Washington's call for new nuclear negotiations at the same time as it reimposes crippling sanctions "doesn't make sense" and is an attempt at "psychological warfare".
In a televised interview, he said if you're an enemy and you stab the other person with a knife and then you say you want negotiations, then the first thing you have to do is remove the knife.
It was his first response to US President Donald Trump 's offer of talks on a new deal to replace a 2015 pact he abandoned in May, and came as Iran braces for the return of sweeping US sanctions today.
Trump's withdrawal from the historic multilateral accord in May infuriated his European partners.
The first round of sanctions takes effect, targeting Iran's access to us banknotes and key industries including cars and carpets.
Iran's currency has lost around half its value since Trump announced the US would withdraw from the pact.
