Russia launched a massive overnight attack on Kyiv with ballistic missiles and drones, killing two people, including children, just hours before Putin's announced "Victory Day truce" was to take effect. The assault involved 5 ballistic missiles and over 180 drones, with Ukrainian forces intercepting 2 missiles and 81 drones.

Ukrainian counterattacks continued with SBU drones striking two key Russian defense factories - Bazalt and Splav - while also disrupting Russian civilian aviation, causing hundreds of grounded flights. These strikes follow Ukraine's historic naval drone attacks that downed Russian fighter jets in previous days.

In diplomatic developments, JD Vance acknowledged Russia's demands in negotiations as "too high" while Biden criticized Trump's approach to ending the war. Germany delivered a new military aid package as the Vatican conclave began but ended its first day without selecting a new pope.
