KYIV, Ukraine — Russia fired 355 drones at Ukraine overnight in the biggest such attack since Moscow's 2022 invasion, Kyiv said on Monday, a day after Russian strikes killed 13 people.
US President Donald Trump earlier said that Russian leader Vladimir Putin had gone "absolutely crazy" in a rare rebuke of the Kremlin chief as Moscow bombed Ukraine during a major prisoner exchange.
Ukraine's air force said Russia had launched "355 Shahed-type drones", including decoys, as well as nine cruise missiles, with its spokesman Yuriy Ignat confirming to AFP that it was the largest drone attack since Moscow launched its full-scale invasion in February 2022.
The drone strikes on Monday came after what Kyiv described as a weekend of "terror".
Kyiv has so far not reported deaths from the drone attack, but said that Russian shelling in the last 24 hours had killed one civilian man in the north-eastern Sumy region, which has been under relentless Russian attack for several months.
Air alerts in Kyiv lasted for six hours, the capital's authorities said.
In the western Khmelnytsky region, local authorities said that 18 residential buildings were damaged by Russian drones.
A Russian attack also wounded a 14-year-old boy in the southern Odesa region, the region's governor said.
Diplomatic efforts to end the three-year war have stepped up a gear in recent weeks, with Russian and Ukrainian officials holding direct talks in Istanbul earlier this month for the first time in three years.
Both sides swapped 1,000 people each over the weekend in their biggest ever prisoner exchange, while Russia said it was preparing a document outlining its peace terms for ending the war.
But Moscow has repeatedly rejected proposals for a 30-day ceasefire from Kyiv and its Western allies, while grinding forward on the front line.
