Russian forces were ramping up attacks in eastern Ukraine on Wednesday, Moscow and Kyiv said, as they vie to secure elusive territorial gains before the end of the year.
Despite the frontlines having barely shifted in 2023, fighting has remained intense, with the nearly encircled industrial town of Avdiivka the latest major flashpoint.
Russia launched a renewed bid to capture the war-battered town last month and analysts suggest Moscow's forces have made incremental gains, though at an enormous human cost.
"The enemy has doubled its artillery fire and airstrikes. It has also intensified ground infantry attacks, and is using armoured vehicles," said Oleksandr Shtupun, a spokesman for Ukraine's army.
Improving weather conditions -- following intense storms across southern Ukraine and Russia earlier this week -- had enabled Russia's forces to intensify their assaults and use drones again, he said.
Oleksandr Tarnavsky, the Ukrainian commander responsible for the area, also said Russia had "significantly increased" its activity around Avdiivka.
He said Russian forces had carried out nearly 20 airstrikes, launched four missiles, thrown 56 assault waves at his forces, and fired more than 1,000 artillery rounds.
- 'Holding the line' -
Avdiivka sits in a strategically important indent in the Russian frontlines of the Donetsk region, with Russia's troops surrounding the town on almost three sides.
But Ukraine has so far held off the Russian bombardment and British intelligence said that recent weeks had "likely seen some of the highest Russian casualty rates of the war so far."
Ukraine's fortifications on its southern edge are just five kilometres (3 miles) north of Donetsk city, the capital of a region Moscow claimed to have annexed last year.
Kyiv has also maintained control of an eight-kilometre wide strip of land -- and a vital supply road -- stretching from the city to the northwest.
On Wednesday, Ukraine's Tarnavsky said his forces were "firmly holding the line along the Avdiivka front."
Around 50 kilometres (30 miles) north, Russia's military claimed separately it had taken control of Khromove, a small village on the outskirts of Bakhmut.
"Troops, supported by aviation and artillery fire, improved their positions along the front line and liberated the village of Artemovskoye," Russia's defence ministry said in a daily briefing, referring to the village by a previous version of its name.
AFP was unable to verify either side's claims.
Both Moscow and Kyiv also said they had downed enemy drones and missiles overnight.
Ukraine is bracing for Russia to increase its attacks on its energy infrastructure in a repeat of Moscow's tactics last winter, which saw millions left without power and heating for hours in sub-zero temperatures.
The national energy company Ukrenergo reported a shortage of electricity on Wednesday as it scrambled to reconnect thousands of villages to the power grid following storms earlier this week.
Ukraine's air force said it downed all 21 drones and two of three X-59 guided missiles that Russia had fired at its territory overnight.
The third missile did not reach its target, it added.
- Poison plot -
Russia said it downed a Ukrainian drone flying towards the capital Moscow and another over the southern Rostov region, the military headquarters for its invasion.
It said there were no injuries or damage caused by falling debris.
The Kremlin on Wednesday also responded to Ukrainian claims that Moscow had poisoned the wife of its military intelligence chief.
Marianna Budanova, the wife of Ukraine's spymaster Kyrylo Budanov, was hospitalised with heavy metals poisoning, in what intelligence figures in Kyiv allege was a brazen assassination attempt.
"Ukraine blames Russia for everything. Even its own existence, it seems to me," Kremlin spokesman Dmitry Peskov told reporters Wednesday in response to the allegations.
On the diplomatic front, US Secretary of State Antony Blinken on Wednesday told a NATO meeting that Washington and its allies remained steadfast in their backing for Ukraine, as doubts escalate over the West's commitment to continue backing Kyiv as the war appears to have ground to a stalemate.
