Foreign Minister Sergey Lavrov said on Friday that Russia will not hesitate to respond to any new deployment of missiles by the United States. 'We will have a mirror reaction', Lavrov said. 'Every step will have a Russian reaction,' Lavrov said at a news conference in Rome with his Italian counterpart, speaking through an Italian interpreter. Russia has proposed a moratorium on the deployment of short and intermediate-range nuclear missiles in Europe after the Intermediate-range Nuclear Forces Treaty (INF) banning such a move formally ended in August.
