Three people were killed in a Russian drone attack on a residential building in the Ukrainian capital Kyiv on Monday morning, an official in the presidential office said.
Kyrylo Tymoshenko, the deputy head of President Volodymyr Zelensky's office, wrote on the Telegram messaging app that 19 people had been rescued from the residential building and rescue work was continuing.
Ukraine's interior minister reported several deaths across the country following the Russian attacks, but did not give a more precise death toll.
A woman was killed in Russian drone attacks on Kyiv on Monday and one person was still trapped under the rubble, city mayor Vitali Klitschko said.
"Everything that is happening (here) is terrorism," he told reporters after residential buildings were hit during the drone strikes, which Prime Minister Denys Shmyhal said also struck an energy facility.
The central Shevchenkivskyi district of Ukraine's capital was rocked by blasts early on Monday for the second time in a week, with Mayor Vitalii Klitshchko saying several residential buildings were damaged.
"Rescuers are on the site," Klitshchko said on the Telegram messaging service, adding that as a result of what he said was a drone attack, a fire also broke out in a non-residential building.
Kyiv's Mayor Vitali Klitschko said on Monday that two more blasts hit the city's central Shevchenkivskyi district, following earlier Monday morning explosions.
There was no immediate information on casualties.
Shevchenkivskiy district, a busy hub with universities, student bars and restaurants, was hit by several explosions on Monday last week when Russia ordered the biggest aerial offensive against Ukrainian cities in retaliation for a blast on a bridge linking mainland Russia to Crimea.
Several people were also killed in Russian air attacks on Ukrainian cities on Monday, Ukrainian Interior Minister Denys Monastyrskyi said.
Attacks were carried out with "suicide drones"
Andriy Yermak, head of the Ukrainian president's staff, said the attacks were carried out with so-called suicide drones.
"Russians think this will help them, but such actions are just their convulsions," Yermak said on the Telegram messaging app.
