Ukrainian President Volodymyr Zelenskiy said on Monday he and U.S. envoy Keith Kellogg had held a good meeting and discussed exerting pressure on Russia to hold "real talks" on ending more than three years of war.

Ukraine's air force said Russia launched 72 drones and one Iskander-M ballistic missile into the country in its latest overnight barrage, of which 48 drones were intercepted or suppressed. The missile and 24 drones impacted across 10 locations, the air force said.

Vice President JD Vance said Russia has made "significant concessions" in talks to end its war with Ukraine but didn't rule out imposing more sanctions on the Kremlin.
