according to regional officials. Russia launched 250 drones and 14 ballistic missiles against Kyiv alone, Ukraine's air force said, causing fires in residential buildings. At least 14 people were injured in the capital. It was one of the biggest combined aerial assaults on the city since the war began.

"With each such attack, the world becomes more certain that the cause of prolonging the war lies in Moscow," Ukrainian President Volodymyr Zelensky said on X. The overnight barrage came as Russia and Ukraine are taking part in prisoner swaps agreed after talks between the two sides in Turkey.Describing a "difficult night", Zelensky said there had been fires and explosions across Kyiv with homes, businesses and cars damaged by strikes or falling debris. Olha Chyrukha, a 64-year-old Kyiv resident, told Reuters news agency: "I wish they'd agree to a ceasefire. To bomb people like this - poor children. My three-year-old granddaughter was screaming scared. "Four people were killed in the eastern Donetsk region; five in the southern Odesa and Kherson regions and four in the northeast Kharkiv region. Residential, facilities and several blocks of flats across Ukraine were damaged. Over 100 people were evacuated, including 13 children from front line areas. Commenting on the combined use of aerial weapons, Timur Tkachenko, head of Kyiv's military administration, said: "The enemy is improving its own tactics of using drones, while simultaneously striking with ballistics. "Zelensky said only "additional sanctions targeting key sectors of the Russian economy" could push Moscow to agree to a ceasefire. Last week, Russia said Ukraine had launched hundreds of exploding drones at the country, including strikes over Moscow. The Russia's defence ministry said that 485 drones had been shot down.  (BBC)
