KYIV, Ukraine (AP) — U.S. President Donald Trump’s special envoy Keith Kellogg said in Kyiv on Monday that officials are “working very, very hard” on efforts to end the three-year war between Russia and Ukraine, as a lack of progress fuels doubts about whether a peace settlement could be on the horizon.

US President Donald Trump on Monday warned that there would be “great consequences” if Russian President Vladimir Putin and Ukraine leader Volodymyr Zelenskyy fail to hold talks to end the ongoing war. Trump reiterated his claim that the conflict would have happened if he were the president in 2022.

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.
