Ukraine fended off 36 Russian air attacks in and around the capital overnight while pro-Kyiv Russian fighters said they were battling Russian forces for a second day inside Russia, trading blame with Moscow for the deaths of two civilians.

Russia has carried out a new massive drone attack on Ukraine's capital Kyiv. Kyiv's mayor Vitaliy Klitschko said a man died when drone wreckage fell near a petrol station. A woman was injured. Overall, Russia launched a record 54 so-called kamikaze drones on Ukrainian targets, 52 of which were shot down, Ukraine's Air Force reported.

Ukraine's plans for a counteroffensive against Russian occupation remain on track, its deputy defence minister told Reuters on Saturday, despite an "unprecedented" wave of missile and drone attacks across the country in recent weeks.

Ukraine fended off 36 Russian air attacks in and around the capital overnight while pro-Kyiv Russian fighters said they were battling Russian forces for a second day inside Russia, trading blame with Moscow for the deaths of two civilians.

Russia launched a wave of air attacks on Ukraine early on Sunday, with air defence systems repelling all missiles and drones on their approach to Kyiv, the capital's military officials said.

Air defence systems were engaged in the early hours of Sunday in repelling air attacks near Kyiv, the military administration of the Ukrainian capital said on the Telegram messaging channel. Reuters' witnesses reported that there were several blasts heard in the Kyiv region from what sounded like air defence systems hitting targets.
