Overnight Russian drone attacks sparked a fire in Kyiv and injured a woman and damaged several houses in the northeastern city of Sumy, Ukrainian officials said on Monday.
The Ukrainian military said on Monday that it had shot down 61 out of 83 drones with 22 more likely downed by electronic warfare.
No injuries were reported in the attack that sparked a fire at a non-residential building in Kyiv, Mayor Vitali Klitschko said in a post on the Telegram messaging app.
But a 38-year-old woman was hospitalised after Russia launched drones at Sumy, which is the administrative centre of the broader Sumy region, Ihor Kalchenko, governor of the region said on Telegram.
Five houses were also damaged, he added.
The photos posted by the emergency services from the site showed cars engulfed in flames next to a high-rise building with damaged windows.
The emergency services said the attack knocked out more than 300 windows and prompted evacuation of 65 residents from the damaged homes. There was no comment from Russia.
Both sides deny targeting civilians in the full-scale invasion Russia launched in February 2022. But thousands of civilians have died in the conflict, the vast majority of them Ukrainian.
