Russia launched a barrage of missiles at Ukraine overnight Thursday, killing at least four people in the capital Kyiv and hitting infrastructure in the country’s west with a ballistic missile, authorities said,

Russia said that any troops sent to Ukraine by Western governments would be "legitimate combat targets", after Britain and France announced plans to deploy a multinational force there in the event of a ceasefire.

Ukraine's allies said they had agreed to provide the country with multilayered international defense guarantees as part of a proposal to end Russia's nearly 4-year-old invasion of its neighbor.

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 Zelensky condemned Russia's latest strikes on electricity, heating and water infrastructure in Ukraine, which left hundreds of thousands in southeastern Ukraine without power and heat.

Efforts are continuing to restore services in Dnipropetrovsk, officials say, after wide-spread attacks in the southeast.

France and the U.K. signed a “Declaration of Intent” on Tuesday to send their forces to Ukraine in the event of a peace deal with Russia.

President Trump's actions in Venezuela also are causing unease in Western nations and giving the Kremlin fresh talking points to defend its war in Ukraine.

British Prime Minister Keir Starmer said Parliament would be able to vote on whether to deploy troops to Ukraine on a peacekeeping mission.
