Kyiv (Ukraine) (AFP) - Ukraine said Friday it had repelled a night-time drone attack from Russia, a day after Moscow launched a wave of missile strikes in the run-up to New Year celebrations.
A frontline soldier, meanwhile, described the fighting in the east of the country as "butchery", in comments to AFP.
The attacks came 10 months into President Vladimir Putin's invasion of Ukraine, with Russian strikes on the energy grid having left millions in the cold in the middle of winter.
Ukraine's air force said Friday that Russia had targeted the pro-Western country overnight with "Iranian-made kamikaze drones".
A total of 16 drones launched from the southeast and north had all been destroyed by Ukraine's air defence, it said.
In Kyiv, Mayor Vitali Klitschko said seven drones had targeted the capital.Two were shot down "on approach" and five over the city.
There were no casualties, but falling debris damaged windows in two buildings in southwestern Kyiv, he added.
'Butchery'
The drone attack came after a barrage of Russian missiles battered Ukraine on Thursday morning, with blasts reported across the vast country, from the northeastern city of Kharkiv to Lviv in the west near the Polish border.
Ukraine's army said Russia had launched several dozen cruise missiles, most of which had been shot down.
Russia's defence ministry said Friday it had carried out a "massive strike" the day earlier on military command and energy facilities.
"All assigned targets were reached," it added.
Tymoshenko said four civilians had been killed and eight wounded on Thursday.
On Friday, three people were killed by Russian shelling, he added.
Following months of humiliating defeats, Russian forces are now seeking to wrest control of the eastern region of Donetsk where the city of Bakhmut has become the epicentre of fighting.
A fighter of the 28th brigade stationed south of Bakhmut called the ongoing fighting "butchery."
"The situation is very complicated for our infantrymen on the front, we support them as best we can," said the 24-year-old artilleryman who goes by the call sign "Avatar" and operates a mortar donated by Finland.
Members of Russia's private mercenary group Wagner have been at the forefront of the battle for Bakhmut.
Avatar said that eight months on, Wagner has been unable to defeat Ukrainians who he said are "killing these men one after the other".
Putin speaks to Xi
Ukrainian President Volodymyr Zelensky said most regions had been left without power following Thursday's attack.
Ukraine's energy operator said Friday the damage had had a "much smaller impact" on the power grid than "the enemy expected" and the power deficit was back to the levels before Thursday's attack.
But "the situation in the southern and eastern regions is still difficult," Ukrenergo added.
Russia has faced international condemnation and waves of unprecedented sanctions over its war in Ukraine.
On Friday, the head of the International Olympic Committee, Thomas Bach, said sporting sanctions imposed on Belarus and Russia should remain in place in 2023.
The international isolation has forced Putin to seek closer political and economic cooperation with nations in the Middle East, Africa and Asia.
A pariah in the West since the start of the assault on Ukraine, Putin on Friday spoke by video link with Chinese leader Xi Jinping, calling him a "dear friend" and hailing the two countries' efforts to counter Western "pressure".
Putin also said he was keen to ramp up military cooperation.
"We aim to strengthen cooperation between the armed forces of Russia and China," Putin told Xi, a week after the two countries conducted naval drills in the East China Sea.
Putin also hailed the efforts of Moscow and Beijing to counter "unprecedented Western pressure and provocations" and said he expected Xi to arrive in Moscow for a state visit next spring.
And on Friday, the Kremlin announced that soldiers, police and other state employees deployed in Ukraine would be exempt from income tax, the latest in a series of incentives to encourage support of its military operation there.
Putin has also relied on the backing of Belarus strongman Alexander Lukashenko, who allowed Russian troops to use his country as a launchpad for the offensive.
In a first, Minsk said Thursday its forces had downed a Ukrainian air defence missile in the western Brest region that borders Poland and Ukraine.
Kyiv has suggested it might have been part of a Russian ploy to try to draw Belarus into the conflict.
But the Belarusian defence ministry said Friday it was considering the possibility that the incident was a "deliberate provocation" by Ukrainian forces.
The Kremlin said Friday the incident had caused "extreme concern" in Minsk and Moscow.
