Kiev, 25 May 2025 (dpa/MIA) - At least eight people have died and dozens were injured in overnight Russian drone attacks across Ukraine, Ukrainian officials said on Sunday.

Kiev regional governor Mykola Kalashnyk said three people had died and two children were among at least 10 of those injured.

Emergency services and medical teams were working across the region, Kalashnyk wrote on Telegram.

"The enemy air attack continues. Please stay in safe places until the danger passes," he warned residents.

Kiev Mayor Vitali Klitschko said debris from a falling drone had hit a student dormitory, while a house had been damaged in another incident.

He too warned of continued danger and urged residents to remain in shelters.

Teymur Tkachenko, head of the city's military administration, said dozens of kamikaze drones had flown over Kiev. Air defence had been deployed to repel the attacks, he wrote on Telegram.

In the southern city of Mykolaiv, one person was killed and five others were injured when a drone hit residential building, Ukraine's State Emergency Service reported.

In the western region of Khmelnytskyi at least four people had been killed following Russian shelling, the head of the region's administration Sergii Tiurin wrote on Facebook.

Five others had been injured and taken to hospital, one of them in serious condition, he wrote.

Six residential buildings had been destroyed and more than 20 houses damaged in the attacks, he added.

Russian drone attacks were also reported from Kharkiv in the east and the port city of Odessa.

The previous night, at least 15 people were injured after Russian drone attacks on Kiev. Ukrainian President Volodymyr Zelensky said 250 drone attacks and airstrikes with 14 ballistic missiles were recorded.

Meanwhile, Russia and Ukraine are expected to continue their largest prisoner exchange to date on Sunday. On Saturday, the two released 307 people each.

The two sides have agreed to release a total of 1,000 prisoners each this week in the largest swap since Russia's full-scale invasion in February 2022, with the first 390 freed on Friday.

It was the only concrete result of the first direct Russian-Ukrainian negotiations since 2022, which had been encouraged by US President Donald Trump.
