Former Russian president Dmitry Medvedev said on Monday that supplying U.S. Tomahawk missiles to Ukraine could end badly for everyone, especially U.S. President Donald Trump.

Russian drone and missile strikes caused blackouts across large swaths of Ukraine, damaged residential buildings and injured at least 20 people in Kyiv, authorities said.

US President Donald Trump is considering sending Tomahawk long-range cruise missiles to Ukraine, saying it would provide "a new step of aggression" in its war with Russia. When asked on Air Force One if he would send Tomahawks to Ukraine, Trump replied "we'll see... I may".

President Donald Trump calls Tomahawk missiles a 'new step of aggression' while considering sending the weapons to Ukraine against Russia.

U.S. President Donald Trump said on Sunday he may offer long-range Tomahawk missiles that could be used by Kyiv if Russian President Vladimir Putin does not end the war in Ukraine.
