Many of the drones aren’t particularly fast or high-tech, but they are cheap enough for the Kremlin to launch more than 700 in one night, in an effort to overwhelm Ukraine’s air defenses. Here’s what we know.

Special U.S. envoy Steve Witkoff says Russian leader Vladimir Putin agreed to allow the U.S. and Europe to offer Ukraine a security guarantee resembling NATO's collective defense mandate.

Ukrainian officials say more than 19,000 children have been unlawfully deported to Russia or occupied areas, with reports suggesting the number could be far higher.

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.

President Donald Trump on Sunday night declared that Kyiv would not be regaining Moscow-annexed Crimea, nor would it be allowed to join NATO.

As the front lines froze, and air defenses got better, Russia and Ukraine pivoted away from close bombing runs to standoff attacks.
