At least 63 Russian soldiers have been killed in a Ukrainian strike on the occupied city of Makiivka, Russia's defence ministry admitted on Monday.
Kyiv has claimed that around 400 Russian soldiers died and 300 were injured in the incident, which happened at a temporary accommodation centre.
Euronews is unable to independently verify this claim.
A spokesman for Russia's defence ministry said four missiles hit the structure but did not give a date for the attack.
Russian-backed Donetsk official Daniil Bezsonov said HIMARS rockets hit the centre -- a vocational school -- on 1 January.
"Apparently, the high command is still not aware of the capabilities of this weapon (HIMARS)," he wrote on Telegram. "I hope that the perpetrators who made the decision to use this facility will be punished. In the Donbas, there are enough abandoned facilities with strong buildings and basements where you can disperse the placement of personnel. And if everything is busy, then for a long time it was possible to dig bunkers with mine construction equipment."
A new airstrike targeted Kyiv in the early hours of Monday, according to authorities in the Ukrainian capital.
Serguiï Popko, head of the military administration in Kyiv, reported that "20 aerial targets had been shot down".
It comes after a New Year's Day marked by dozens of Russian strikes that left at least four people dead and 50 injured in the capital and elsewhere in the country.
The attacks continue to target critical infrastructure, with Moscow claiming to it was aiming for unmanned aircraft manufacturing facilities.
Russia has been attacking Ukraine's energy infrastructure for months, with millions losing power amid sub-zero wintry temperatures in the country.
