Russia has launched the largest aerial attack on Ukraine over a 24-hour period since the war began, hitting cities across the country with 948 drones.
Ukraine's Air Force said 556 drones had been fired since 09:00 local time (07:00 GMT) on Tuesday, in an unusual daytime attack which killed at least three people and injured dozens.
In the western city of Lviv, the 16th century Bernardine monastery - part of a UNESCO World Heritage site in the city centre - was damaged, local officials said.
In the neighbouring Ivano-Frankivsk region, a maternity hospital was hit.
Those strikes came after an overnight Russian attack left five people dead. Ukraine said 392 drones and 34 missiles were fired.
In his video address on Tuesday evening, Ukrainian President Volodymyr Zelensky said the scale of the latest attacks clearly shows that Russia has no intention of really ending this war.
Russia's military has not publicly commented on the attacks.
A video posted earlier on Tuesday by Lviv authorities showed a fire burning through the roof of a residential building near the Bernardine monastery.
Separate footage posted on social media showed a drone flying lower over the city and hitting the residential building.
Lviv regional head Maksym Kozytskyi said 32 people were injured in the Russian attack.
In the city of Ivano-Frankivsk, two people were killed and another four - including a six-year-old child - were injured, local officials said. Various buildings - including a maternity hospital - were damaged in the regional capital.
Regions such as Ternopil and Vinnytsia also experienced drone strikes, contributing to the death toll and injuries across various cities.
Despite the extensive use of aerial drones, Ukraine's Air Force managed to intercept many of them, but acknowledged there were multiple direct hits across the country.
This attack is part of a continuous pattern of aggression since Russia began its invasion of Ukraine in February 2022.
