Iran has filed a complaint with the International Court of Justice (ICJ) to "hold [the] US accountable for its unlawful re-imposition of unilateral sanctions," Iranian Foreign Minister Mohammad Javad Zarif said on Twitter Monday.

"Iran is committed to the rule of law in the face of US contempt for diplomacy & legal obligations. It's imperative to counter its habit of violating int'l law," the tweet read.

Zarif did not expand on the claim it would bring before the ICJ, but officials have repeatedly accused the US of imposing illegal sanctions on Iran after pulling out of the Joint Comprehensive Plan of Action (JCPOA), known colloquially as the Iran nuclear deal, in May.

Under the deal signed in Vienna with six world powers - the US, UK, France, Germany, Russia, China and the European Union - Iran scaled back its uranium enrichment programme and promised not to pursue nuclear weapons.

In exchange, international sanctions were lifted, allowing it to sell its oil and gas worldwide. However, secondary US sanctions remained.

Following that withdrawal, the US announced it would re-impose sanctions targeting critical sectors of Iran's economy, such as its energy, petrochemical, and financial sectors.

Last week, Trump said that with the US increasing sanctions on Iran, "at a certain point they're going to call me and say 'let's make a deal,' and we'll make a deal."

Iran responded to those remarks by saying it would not be Iran that would call the US, but Trump would call Iran.

Foreign Ministry spokesman Bahram Ghasemi said on Monday that "maybe someday he will call Tehran and ask for negotiations - this is more likely."

Earlier this month, the US said that the goal was to get as many countries as possible down to zero Iranian oil imports and it has repeatedly said it could potentially also target countries that kept doing business with Iran.

"Our goal is to increase pressure on the Iranian regime by reducing to zero its revenue on crude oil sales," said State Department Director of Policy Planning Brian Hook. (Aljazeera)
