Russia launched a massive overnight assault on Ukraine, firing 614 projectiles in what marks the most extensive aerial strike in three weeks. The Ukrainian Air Force reported intercepting or electronically jamming 546 drones and decoys, along with 31 missiles. Despite these efforts, strikes landed in 11 locations, including in Western Ukraine.

Moscow continues to throw cold water on the prospect of Putin-Zelenskyy meeting, and is insisting Russia have a role in security guarantees for Ukraine.

President Trump pledges no U.S. troops will defend Ukraine, focusing instead on arranging a Putin-Zelenskyy meeting.
