Wave of drone and missile strikes that wounded dozens was retaliation for ‘terrorist attack’, says Moscow

• Russia-Ukraine war – latest news updates

Moscow has said the wave of drone and missile strikes that wounded at least 28 people in Ukraine’s second-biggest city late on Saturday was launched in retaliation for the “terrorist attack” on the Russian border city of Belgorod earlier the same day that reportedly killed 24 people.

Ukraine’s national police said on Sunday that at least six Russian missiles had reached Kharkiv on Saturday night, injuring more than two dozen people and hitting 12 apartment buildings, 13 residential houses, a hotel and a kindergarten.

Russia launches overnight air assault targeting Kyiv, Ukraine says; Moscow reports 21 dead after Ukrainian strike on Belgorod

Russia launched a bombardment on Ukrainian regions in the hours leading into New Year’s Eve, targeting Kyiv and inflicting damage on residential areas of the city of Kharkiv, Ukrainian officials said. Ukraine’s air defence systems in the region surrounding Kyiv were engaged in repelling Russia’s drone attack, the military administration of the region said on Telegram.

The Kharkiv mayor, Ihor Terekhov, said the drone attack came in several waves, hitting residential buildings in the city centre and starting fires. “All relevant emergency services are already on the site. Information about potential casualties is being clarified.”

Ukraine carried out a series of strikes on the Russian border city of Belgorod, the day after an 18-hour aerial barrage across Ukraine killed at least 41 civilians. Russian officials said the shelling in the centre of Belgorod on Saturday killed 21 people, including three children, and injured 110 more. Ukrainian media – citing law enforcement agencies – said the attacks only hit military targets and were retaliation for Friday’s mass bombardment of Ukrainian cities.

The Belgorod attack came a day after Ukraine said a barrage of Russian missile strikes on several cities killed at least 40 people, wounding dozens more.

Russia experienced a sharp rise in the number of killed and wounded troops in 2023, due to “degradation” of military quality, according to the UK’s Ministry of Defence.

In its daily intelligence briefing, the MoD said the average daily number of Russian casualties (killed and wounded) had risen by almost 300 a day compared with 2022. “The increase in daily averages, as reported by the Ukrainian authorities, almost certainly reflects the degradation of Russia’s forces and its transition to a lower quality, high quantity mass army since the ‘partial mobilisation’ of reservists in September 2022.”

Moscow would not give an explanation for a missile in Polish airspace unless provided with “hard evidence” it was Russian, said Andrei Ordash, Russia’s chargé d’affaires in Poland, after being summoned to the Polish foreign ministry. Poland’s armed forces said an unknown airborne object, which they identified as a Russian missile, entered Polish airspace from the direction of Ukraine for less than three minutes. “Until hard evidence is provided, we will not give any explanations, because these accusations are unfounded,” Ordash said.
