Russian President Vladimir Putin has announced that Moscow is boosting its nuclear arsenal. <br /><br /> It comes after Kremlin officials denounced a US plan to station tanks and heavy weapons in NATO states along Russia’s border. <br /><br /> They say it is the most aggressive American act since the Cold War. <br /><br /> “More than 40 new intercontinental ballistic missiles, able to overcome even the most technically advance anti-missile defence systems, will be added to the make-up of the nuclear arsenal this year,” said Putin. <br /><br /> Tension is high between Russia and the US over the Ukraine crisis and other issues. <br /><br /> Moscow has warned that it will retaliate if Washington goes ahead with its military equipment manoeuvres.<br /><br /> Poland and the Baltic states are welcoming America’s plans.
