Russia says will take 'all necessary retaliatory steps' if US nuclear weapons appear in Poland

Russia on Monday said it will take necessary steps if US nuclear weapons appear in neighboring Poland.

"The military, of course, if such plans are implemented, will analyze the situation and in any case will do everything necessary, all the necessary retaliatory steps, to guarantee our security," Kremlin spokesman Dmitry Peskov told reporters at a press briefing in Moscow.

Peskov's remarks came after Polish President Andrzej Duda said in an interview with local media earlier in the day that his country would allow the deployment of nuclear weapons on Polish territory "if this is the decision of our allies.”
