Ukraine said its forces had repelled Russian assaults along the length of the front line on Thursday on the eve of the war's anniversary, as President Vladimir Putin, empty-handed after a bloody winter offensive, talked up Russia's nuclear arsenal.
After a series of strident speeches in the runup to the anniversary of his invasion, Putin announced plans on Thursday to deploy new Sarmat multi-warhead intercontinental ballistic missiles this year. Earlier this week he suspended Russia's participation in the START nuclear arms control treaty.
