Tasnim � Iran�s Foreign Minister Mohammad Javad Zarif said Washington�s escalating economic pressure campaign against the Iranian nation reveals the �panic and desperation� of the US and its �client co-conspirators�.

�Escalating #EconomicTERRORISM against Iranians exposes panic & desperation of US regime�and chronic failures of its client co-conspirators. REAL news, @realdonaldtrump: Inheritors of ancient Persian civilization don't base strategy on "advice" of foreigners�let alone Americans,� Zarif tweeted on Tuesday.

It came after US President Donald Trump suggested on Monday in a tweet that former Secretary of State John Kerry has provided Iran with �very bad advice� and may have violated US law by advising the Islamic Republic.

�Iran is being given VERY BAD advice by John Kerry and people who helped him lead the US into the very bad Iran Nuclear Deal,� Trump wrote on Twitter on Monday.

"Big violation of Logan Act?� Trump asked.

In May last year, Trump pulled the US out of the Iran nuclear deal, known as the Joint Comprehensive Plan of Action (JCPOA), claiming that it was a bad deal.

Kerry, who served during the administration of former US President Barack Obama and played a main role in the nuclear talks, has criticized the Trump administration for pulling out of the accord.

Kerry has described it as the �single strongest, single most accountable, single most transparent nuclear agreement anywhere in the world.�
