A Russian "guided bomb" has hit a blood transfusion centre in north-eastern Ukraine, killing two people and injuring four, Ukrainian officials say.
Volodymyr Zelensky posted an image of the building on fire as a result of Saturday night's attack in around Kupiansk, in the Kharkiv region.
The city of Kupiansk and nearby settlements were seized by Russian troops in the first few days of Moscow's full-scale invasion of Ukraine, launched in February 2022.
President Zelensky also said that on Saturday Russia separately carried out a missile attack, targeting an aeronautical company run by group Motor Sich in the western Khmelnytskyi region.
On Sunday, Russia's air defences destroyed a drone as it approached Moscow, the city's mayor, Sergei Sobyanin, said.
Last week, an office block on a Moscow skyscraper was hit two days in a row by Ukrainian drones, Russian authorities said.
