Polish Foreign Minister Jacek Czaputowicz says that Iran has not been invited to an international conference on the Middle East in Warsaw next month. Czaputowicz said in remarks published on Monday that Iran’s presence would have hampered talks because the language that Tehran uses is “hard to accept.” Iran has protested over the February 13-14 conference, calling it a hostile move. Poland and the US are co-hosting the event, which has also been met with a lukewarm reaction from the European Union, whose foreign policy chief Federica Mogherini will not be attending. Czaputowicz also said Russia has advised that it will not participate either, AP reports. The Polish FM insists that the conference could help solve the impasse over the international agreement on curbing Iran’s nuclear ambitions.
