At least 10 Ukrainian drones were shot down on their approach to Moscow overnight into Sunday morning, according to the city's mayor.

A Russian drone strike in Ukraine left at least five people dead, including a 1-year-old and his mother and grandmother, in an attack occurring just hours after President Donald Trump and Russian President Vladimir Putin spoke over the phone.

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.
