Angered by US Secretary of State Mike Pompeo's announcement that Poland will host an international conference on Iran in mid-February, Iranian authorities on Sunday summoned Warsaw's top diplomat in the country and called off a Polish film festival.
The moves followed a tweet by Iran's Foreign Minister Mohammad Javad Zarif who denounced the upcoming summit as America's anti-Iran "circus."
Mr Pompeo is currently on a Middle East tour, bringing the Trump administration's anti-Iran message to the region. He told Fox News before departing from Cairo on Friday that an international conference on Iran and the Middle East will take place in Poland on 13 and 14 February.
The official IRNA news agency said Iran conveyed its protest over this to Poland's Charge d'Affaires Wojciech Unolt, demanding that Poland not side with this "hostile move" by the United States against Tehran.
The statement quoted an unnamed Iranian official as saying that if the summit goes ahead, Iran will resort to unspecified "counter-action" towards Poland, without elaborating.
Separately, Iran's culture ministry in a statement said it was suspending "Poland's Film Week," supposed to be held in Tehran in late January, until Warsaw mends its ways and starts applying "appropriate behaviour" towards Tehran.
Poland's Foreign Ministry in Warsaw could not immediately be reached for comment on Sunday morning. However, Foreign Minister Jacek Czaputowicz said Saturday he hoped the conference will provide a new platform for international dialogue and allow the US and European Union to find a closer position on Iran.
