A ballistic missile attack was under way in Kyiv early Sunday, with the city’s mayor warning residents to remain in shelters. “Air defence forces are operating in the capital. Remain in shelters!”, the capital’s mayor Vitali Klitschko said on Telegram. Explosions and several flashes in the sky have been reported.

The attack follows civilian deaths on both sides of the ​Russia-Ukraine border on Saturday. Russian strikes in Dnipropetrovsk in central-eastern Ukraine and the northern Sumy region killed two people, while Ukraine launched attacks on Volgograd and Belgorod in Russia’s southwest, and Horlivka, in the Donetsk region of Ukraine, which is controlled by Moscow. Three people were killed in the attacks, regional authorities said.

In the Russian border region of Bryansk, ⁠a Ukrainian drone strike on Saturday killed two people in their car in a village near the border, ⁠the region’s acting governor Yegor Kovalchuk said on Telegram. Russia’s defence ​ministry, quoted by Russian ‌news agencies, said ‌124 Ukrainian drones had been downed over Russian regions over ‌a period extending from 8 am to 8pm.

More than 40 drone strikes and artillery fire had killed one person and injured one near Nikopol, according to the governor of the ​southeastern Dnipropetrovsk region in Ukraine, Oleksandr Ganzha. The town, lying ⁠on the opposite bank of the Dnipro River from ​the ​Russian-held Zaporizhzhia nuclear power ​plant, is a frequent Russian target.
