Some 63 Russian soldiers have been killed by a Ukrainian strike on a military facility in the eastern Donetsk region.
Ukrainian forces fired six rockets from a HIMARS launch system and two of them were shot down, a Russian defence ministry statement said.
The strike, using a US-supplied precision weapon that has proven critical in enabling Ukrainian forces to hit key targets, delivered a new setback for Russia which in recent months has reeled from a Ukrainian counteroffensive.
The Strategic Communications Directorate of Ukraine’s Armed Forces claimed on Sunday that some 400 mobilised Russian soldiers were killed in a vocational school building in Makiivka and about 300 more were wounded.
That claim could not be independently verified. The Russian statement said the strike occurred “in the area of Makiivka” and did not mention the vocational school.
According to the governor of Russia’s Samara region, Dmitry Azarov, an unspecified number of residents of the region were among those killed and wounded by the strike on Makiivka.
Russian military bloggers, whose information has largely been reliable during the war, said ammunition stored close to the facility had exploded in the attack and contributed to the high number of casualties.
Daniil Bezsonov, an official with the Russian-appointed administration in Russian-occupied Donetsk, called for the punishment of military officers who ordered a large number of troops to be stationed at the facility.
The Ukrainian military appeared to acknowledge the attack on Monday, with the General Staff confirming that Makiivka was hit on December 31, and saying 10 Russian military vehicles were destroyed or damaged. It added that Russian personnel losses were still being clarified.
Meanwhile, Russia deployed multiple exploding drones in another nighttime attack on Ukraine, officials said on Monday, as the Kremlin signalled no let-up in its strategy of using bombardments to target the country’s energy infrastructure and wear down Ukrainian resistance to its invasion.
The barrage was the latest in a series of relentless year-end attacks, including one that killed three civilians on New Year’s Eve.
On Monday, Kyiv Mayor Vitali Klitschko said that 40 drones “headed for Kyiv” overnight. All of them were destroyed, according to air defence forces.
The mayor said 22 drones were destroyed over Kyiv, three in the outlying Kyiv region and 15 over neighbouring provinces.
Energy infrastructure facilities were damaged as the result of the attack and an explosion occurred in one city district, the mayor said. It was not immediately clear whether that was caused by drones or other munitions. A wounded 19-year-old man was hospitalised, he added, and emergency power outages were under way in the capital.
In the outlying Kyiv region a “critical infrastructure object” and residential buildings were hit, Governor Oleksiy Kuleba said.
Russia has carried out airstrikes on Ukrainian power and water supplies almost weekly since October.
Ukrainian President Volodymyr Zelensky has accused Russia of “energy terrorism” as the aerial bombardments have left many people without heat amid freezing temperatures. Ukrainian officials say Moscow is “weaponising winter” in its effort to demoralise the Ukrainian resistance.
Ukraine is using sophisticated Western-supplied weapons to help shoot down Russia’s missiles and drones, as well as to send artillery fire into Russian-held areas of the country.
Moscow’s full-scale invasion on February 24 has gone awry, putting pressure on Russian President Vladimir Putin as his ground forces struggle to hold ground and advance.
He said in his New Year’s address to the nation that 2022 was “a year of difficult, necessary decisions”.
Mr Putin insists he had no choice but to send troops into Ukraine because it threatened Russia’s security — an assertion condemned by the West, which says Moscow bears full responsibility for the war.
Russia is currently observing public holidays through to January 8.
Drones, missiles and artillery shells launched by Russian forces also struck areas across Ukraine.
Five people were wounded in the Monday morning shelling of a Ukraine-controlled area of the southern Kherson region, its Ukrainian governor Yaroslav Yanushevich said on Telegram.
The Russian forces attacked the city of Beryslav, the official said, firing at a local market, likely from a tank. Three of the wounded are in serious condition and are being evacuated to Kherson.
Seven drones were shot down over the southern Mykolaiv region, according to Governor Vitali Kim, and three more were shot down in the southeastern Dnipropetrovsk region, Governor Valentyn Reznichenko said.
In the Dnipropetrovsk region, a missile was also destroyed, according to Gov Reznichenko. He said that energy infrastructure in the region was being targeted.
Ukraine’s Air Force Command reported on Monday that 39 Iranian-made exploding Shahed drones were shot down overnight, as well as two Russian-made Orlan drones and a X-59 missile.
“We are staying strong,” the Ukrainian defence ministry tweeted.
A blistering New Year’s Eve assault killed at least four civilians across the country, Ukrainian authorities reported, and wounded dozens. The fourth victim, a 46-year-old resident of Kyiv, died in a hospital on Monday morning, Mayor Klitschko said.
Multiple blasts rocked the capital and other areas of Ukraine on Saturday and through the night. The strikes came 36 hours after widespread missile attacks Russia launched on Thursday to damage energy infrastructure facilities, and the unusually quick follow-up alarmed Ukrainian officials.
In Russia, a Ukrainian drone hit an energy facility in the Bryansk region that borders with Ukraine, Bryansk regional governor Alexander Bogomaz reported on Monday morning. A village was left without power as a result, he said.
