Watch Jake Tapper’s exclusive interview with President Joe Biden on CNN Tonight with Jake Tapper at 9 p.m. ET Tuesday. CNN —

  President Joe Biden spoke with Ukrainian President Volodymyr Zelensky on Monday after a barrage of Russian missiles targeted cities across Ukraine, condemning the strikes and pledging continued US security assistance “including advanced air defense systems.”   

  During the call, a White House statement said, Biden “expressed his condemnation of Russia’s missile attacks across Ukraine, including Kiev, and expressed his condolences to the families of those killed and injured in these senseless attacks.  President Biden pledged to continue providing Ukraine with the support it needs to defend itself, including advanced air defense systems.”   

  The White House did not specify which air defense systems Biden discussed with Zelensky, but the United States previously committed to providing Ukraine with National Advanced Surface-to-Air Missile Systems.  NASAMS will be capable of engaging Russian cruise missiles.   

  Biden, the statement said, “also underscored his continued commitment to allies and partners to continue to impose costs on Russia, hold Russia accountable for its war crimes and atrocities, and provide Ukraine with security, economic and humanitarian aid”.   

  Asked whether the attacks of the past 24 hours would change the calculus of what the US could offer Ukraine, a senior administration official said they had no announcements to make on that front, but that the US would continue to help providing Ukraine with short and long-range air defense systems, as it had done in the past.   

  And a second senior administration official provided the following summary of air assistance provided to Ukraine by the US: “We have delivered more than 1,400 Stinger anti-aircraft systems to Ukraine, as well as air surveillance and multi-mission radars.  We have enabled our Allies to move their own air defense systems to Ukraine – including the transfer from Slovakia of a critical S-300 system in April.  And in August, President Biden announced a new aid package for Ukraine that included orders for 8 new NASAMS—National Advanced Surface-to-Air Missile Systems.  We will continue to provide Ukraine with everything it needs to defend itself.”   

  In a Defense Department briefing in late September, the US had not yet delivered NASAMS to Ukraine.  Then Tax.  Gen. Patrick Ryder said two systems are expected to be delivered in the next two months, with the remaining six arriving at an unspecified date.   

  Secretary of State Anthony Blinken also spoke with Ukrainian Foreign Minister Dmytro Kuleba on Monday to reiterate US support after the deadly strikes.  Biden is expected on Tuesday to participate in an emergency conference call with G7 leaders during which Zelensky is expected to address the group.   

  Russia fired a total of 84 cruise missiles at targets across Ukraine on Monday, the General Staff of the Armed Forces of Ukraine said in a Facebook post.   

  Russian President Vladimir Putin said the strikes were a response to what he described as “terrorist actions” by Kyiv.  In particular, he referred to Saturday’s explosion on the Kerch bridge connecting Russia with Crimea – which he blamed on Ukraine’s “special services” – and a list of other alleged “crimes”.   

  Kuleba said such claims were “nonsense,” writing in a tweet, “Putin is desperate because of defeats on the battlefield and is using the missile scare to try to turn the tide of the war in his favor.”  And Ukraine’s defense intelligence service claimed in a statement on Monday that Moscow had been planning a “massive” missile attack on Ukraine since early last week.   

  Dmitry Medvedev, the deputy head of Russia’s Security Council, also recently said he believes Moscow should aim for the “complete dismantling” of Zelensky’s “regime”.   

  In a post on Telegram, Medvedev – who served as President of Russia between 2008 and 2012 – said: “The Ukrainian state in its current form … will pose a constant, direct and clear threat to Russia.  Therefore, in addition to the protection of our people and the protection of the country’s borders, the goal of our future actions, in my opinion, should be the complete dissolution of the political regime of Ukraine.”   

  John Kirby, a spokesman for the National Security Council, said Monday that additional aid packages for Ukraine will likely be announced “in the very near future.”   

  “It’s clear he’s feeling the pressure both at home and abroad, and how he reacts to that only he can say,” Kirby told CNN’s Kate Bolduan on “Erin Burnett OutFront.”   

  Kirby added, “He’s well aware that he doesn’t do well on the battlefield.”   

  Asked if he thought such strikes made it more likely that Putin would resort to nuclear weapons, Kirby said the US had seen nothing new.   

  “We’re continuing to monitor his nuclear capabilities, Kate, as best we can.  And what I can tell you today is that we just don’t see any indication that Mr. Putin has made a decision to use weapons of mass destruction or even nuclear weapons.  And we haven’t seen anything, Kate, that would cause us to change our own deterrent posture,” Kirby said.   

  The air defense system report comes amid a series of escalations in the war.   

  Putin last month gave a speech announcing the partial mobilization of some 300,000 reservists after successful Ukrainian counter-attacks, raising the specter of nuclear weapons if he deemed Russia’s “territorial integrity” threatened.  And the Russian president recently announced the annexation of four Ukrainian regions in violation of international law.   

  Last week, Biden issued a stark warning about the dangers of Putin’s nuclear threats, citing the prospect of “Armageddon.”  But multiple US officials said the comment was not based on new information about Putin’s intentions or changes in Russia’s nuclear stance.
