Russia launched its largest barrage of drones and missiles in a month across Ukraine, killing at least three people, Ukrainian President Volodymyr Zelensky said Saturday, as a Kyiv delegation heads to the United States for fresh peace talks.

Adding to his roster of international peace negotiations, President Donald Trump has reportedly proposed putting together a plan to end the over three-and-a-half-year war between Russia and Ukraine, according to several reports citing anonymous sources close to the matter.

The attack came as U.S. officials were expected to hold peace talks with Ukrainian and Russian officials in the coming days.
