Russia used a powerful hypersonic Oreshnik ballistic missile in an overnight missile and drone attack on Kyiv, Ukrainian President Volodymyr Zelenskyy said on Sunday.
Russia's army later confirmed it had used the missile.
The EU's top diplomat Kaja Kallas accused Moscow of using "a political scare-tactic and reckless nuclear-brinkmanship."
She said EU foreign ministers meeting next week would address how to "dial up the international pressure on Russia."
French President Emmanuel Macron condemned the attack, calling Russia's use of the Oreshnik missile "a form of escalation."What do we know about the attack?
