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

At least five people, including a 1-year-old, were killed in a Russian attack on Ukraine just hours after a phone call between President Donald Trump and Russian President Vladimir Putin.

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.
