Though the knock-on effects are unclear, some military commentators have called the strike Russia's "Pearl Harbor." Hopes for direct peace talks, which resumed Monday, remain low.

Russia's overnight attacks killed one person in Ukraine's northeastern region of Kharkiv and injured several more in the northern city of Chernihiv, regional Ukrainian officials said on Tuesday.

Ukraine unleashed more than a hundred drones smuggled deep into Russia in what it called its most damaging attack yet.

The covert operation was described as one for the “history books” by Ukraine’s president. According to Ukrainian officials, nearly a third of Moscow’s strategic bomber fleet was destroyed or damaged with cheaply made drones sneaked into Russian territory in the span of a few hours on Sunday.

After Ukraine’s shocking drone assault on Russian air bases, CNN’s Erin Burnett talks with Former Russian Deputy Minister of Energy Vladimir Milov about how Vladimir Putin might respond.

Steve Bannon warned on the "War Room" podcast that Ukraine's wildly successful drone attack on Russia's strategic bomber fleet could be construed as an act of war, depending on how much help the U.S.

The drone strikes on Russian air force bases weaken Moscow’s ability to wage war on its neighbor and undermine its capacity to threaten more distant rivals.

After too many nights of pulling children from the rubble of Russian drone strikes, the weekend’s devastating attacks on Moscow’s military pride mark a brief respite for Ukrainian morale, and yet another twist of the unexpected.
