Russia warns Western forces deployed to Ukraine under postwar security deal would be "legitimate combat targets" as diplomatic tensions escalate.

The United Kingdom and France have agreed to deploy forces in Ukraine if it strikes a peace deal with Russia, British Prime Minister Keir Starmer said, in a renewed push by Western leaders to guarantee Kyiv’s post-war security and deter Moscow from further aggression.

Ukrainian President Volodymyr Zelenskyy said the agreements were “a signal of how seriously Europe and the entire coalition of the willing are ready to work for real security.”
