Russia has used its latest missile against Ukraine for a second time in the nearly 4-year-old war, a forceful signal to Kyiv and its Western allies as peace talks are in a crucial stage

Russia hit Ukraine with a hypersonic ballistic missile 40 miles away from the border with Poland, in what has been described as a “grave threat” to European security.

Some Moscow commentators said the attack was a warning to European leaders against proposals to deploy their troops to Ukraine as part of a prospective peace deal.
