Iran is about a week away from a self-set deadline that could lead it to significantly escalate its so far limited violations of the 2015 nuclear deal.
US President Donald Trump said on Monday that he knew that Zarif would be attending, and left the door opened for diplomacy with the Islamic Republic.
Iranian foreign minister called on Muslims to end the tyranny of Israel’s policies in Jerusalem and described Israelis as “terrorists”.
"Under current circumstances and if no action is taken (by the Europeans) we will take the next step (in cutting commitments)," Zarif said.
Zarif accuses US of ‘economic terrorism’
Netanyahu’s office added that the prime minister expressed appreciation that Trump planned to increased sanctions against Iran.
Mnuchin said Iranian Foreign Minister Mohammad Javad Zarif would be targeted with U.S. sanctions later this week.
