Russia says a massive Ukrainian drone attack killed at least three people in the Moscow area overnight, calling it the largest and most widespread drone strike since the invasion began.

Moscow's regional governor Andrey Vorobyov reported a woman was killed by a strike on a private residence on the city's outskirts, with two more deaths in the village of Pogorelki.

The Russian Defense Ministry said air defenses intercepted 556 drones from Saturday night into Sunday morning, with another 30 shot down later.

Ukrainian President Volodymyr Zelenskyy confirmed the attack, posting a video of a large plume of black smoke and stating: "Our responses to Russia's prolongation of the war and its attacks on our cities and communities are entirely justified."

This follows a Russian missile and drone barrage earlier this week that killed at least 24 people in Kyiv. Zelenskyy said Russian forces have launched over 3,170 attack drones, more than 1,300 guided aerial bombs, and 74 missiles against Ukraine this week, killing 52 people.

Meanwhile, the two countries exchanged 205 prisoners of war each this week as part of a planned "1,000-for-1,000" swap deal.
