Iran has not been invited to next month’s international conference on the Middle East in Warsaw, said Polish Foreign Minister Jacek Czaputowicz Monday. Irans presence would have hampered talks because the language that Tehran uses is "hard to accept," he explained. Poland and the US are co-hosting the event. Iran has protested the February 13-14 conference, while Russia has declined an invitation. Czaputowicz stressed that the conference could help solve the impasse over the international agreement on curbing Irans nuclear ambitions. US Secretary of State Mike Pompeo had announced the conference earlier this month while on a tour of the Middle East. He said the meeting would "focus on Middle East stability and peace and freedom and security here in this region, and that includes an important element of making sure that Iran is not a destabilizing influence."
