The ongoing conflict between Russia and Ukraine over NATO membership.

NATO Secretary General Jens Stoltenberg expressed confidence in Ukraine's ability to retake more territory from Russian forces, while the US air national guardsman accused of leaking classified defense documents posted sensitive information to a much larger chat group than previously known. A Moscow court ordered the arrest in absentia of Bulgarian investigative journalist Christo Grozev, and Germany, Poland, and Ukraine signed an agreement for a hub to repair Leopard tanks used in Ukraine. The US defense secretary confirmed support for Ukraine and Canada announced new military assistance, while the UK imposed sanctions on five people linked to the arrest of Kremlin critic Vladimir Kara-Murza.
