Russian shelling in southern Ukraine‘s Kherson region killed four people Sunday, including an 87-year-old man and his 81-year-old wife who died after a strike on their apartment building.

The barrage injured nine other people, including a 15-year-old, sparked fires in homes and at a private medical facility, and set a local gas pipeline alight, the head of the regional military administration, Oleksandr Prokudin, said.

“There are no holidays for the enemy,” Andrii Yermak, the head of the Ukrainian president’s office, wrote on social media, commenting on the Kherson attack.

“They do not exist for us as long as the enemy kills our people and remains on our land.”The shelling across Kherson reached the center of the region’s capital city of the same name.

Commanders in the key battle for Avdiivka in Donetsk fear the town will be lost in a matter of days if more international aid cannot be secured – and that huge casualties will be suffered in the process. Arpan Rai reports:

There is a growing sense of alarm among Ukraine’s frontline forces at dwindling supplies of arms and ammunition and signs that the commitment of international partners is faltering, according to multiple senior Ukrainian military officials.

Ukraine’s military fears Vladimir Putin’s forces could break through its defensive lines and secure victory for Russia within days if the US does not commit to more aid, with intense fighting still taking place and hourly assaults targeting the key industrial town of Avdiivka, despite the onset of the country’s bitter winter.

“It is a very difficult situation, very difficult, but the guys from the defence forces are holding their ground,” says Vitaliy Barabash, the head of Avdiivka’s military administration, in an interview with The Independent.

An Orthodox cathedral in Kyiv is hosting its Christmas Eve service today (24 December), after a decree passed earlier this year meaning Ukraine no longer has to celebrate on the same day as the Russian church.

Orthodox Christmas is usually held on 7 January due to the calendar differences, with many of those celebrating the later date by fasting in the 40 days leading up to it.

Russia and Greece have some of the biggest populations of Orthodox Christians, with Ukraine choosing to distance itself from the Putin-aligned date.

Ukraine is prepared to officially celebrate Christmas for the first time on December 25, having previously marked the date on January 7. The Russian Orthodox Church observes the birth of Jesus on January 7.

Some Orthodox Ukrainians observed Christmas on December 25 last year in response to Russia’s February 2022 invasion of Ukraine.

The cathedral in the Monastery of the Caves, a Unesco World Heritage Site in Kyiv, held its Christmas celebration on January 7 of this year, but the service was held in the Ukrainian language for the first time in the 31 years of Ukraine‘s independence from the Soviet Union.

President Volodymyr Zelensky signed legislation in July moving the public Christmas Day holiday to December 25.

However, one of Ukraine‘s two competing Orthodox church organisations is sticking with the January date dictated by the Julian calendar.

To mark Christmas Eve on December 24, Mr Zelensky addressed the nation in a video filmed before the floodlit St Sophia Cathedral in central Kyiv.

He reassured Ukrainians fighting against Russia’s full-scale invasion of the country that “step by step, day by day, the darkness is losing”.

“Today, this is our common goal, our common dream. And this is precisely what our common prayer is for today. For our freedom. For our victory. For our Ukraine,” Mr Zelensky said.

Ex-Wagner chief Yevgeny Prigozhin was killed in a bomb plot orchestrated by Vladimir Putin’s oldest ally, a Russian intelligence officer has claimed.

Mr Prigozhin, who was killed when his plane crashed over Russia on 23 August this year, launched a mutiny against the Russian ministry of defence in June following a long-running feud with officials over the direction of the war in Ukraine.

At the time, the Kremlin denied any involvement with his death and characterised western intelligence assessments of Putin’s culpability as an “absolute lie”.

Russian president Vladimir Putin will continue his war in Ukraine until he achieves “final victory” the EU security chief has warned.

“He will not give up the war, especially not before the American election, which may present him with a much more favorable scenario,” Josep Borrell told The Guardian.

President Volodymyr Zelensky said during a press conference last week that the result of the 2024 US presidential election could “very strongly” influence the course of Russia’s war against Ukraine.

There will be severe consequences if Russian president Vladimir Putin wins the war in Ukraine, the UK’s defence minister has warned.

“If we allow Putin to win this war by dragging it out, and he somehow wins it by exhausting everybody else, then we will suffer the consequences. And the consequences would be incredibly severe for Europe, for Britain, for the world,” Grant Shapps told The Times.

The United Kingdom spent £2.3bn on defence assistance to Ukraine last year and has committed the same amount in 2023.

Russian air defence systems downed four Ukrainian military aircraft over eastern Ukraine in the last day, the Kremlin has claimed.

The defence ministry said it had shot down three Su-27 fighter aircraft and one Su-24 tactical bomber in the Zaporizhzhia and Dnipropetrovsk regions of southeastern Ukraine.

It comes after president Zelensky said his country’s armed forces shot down three Russian Su-34 fighter-bomber aircraft on the southern front.

An eight-year-old boy is among three children to have been rescued from occupied territories by the Ukrainian humanitarian NGO Save Ukraine, reports suggest.

“Three more children from the temporarily occupied territories were returned to the Save Ukraine team. Thus, we completed 14 rescue missions saving 14 children, seven of whom were children deprived of parental care,” the organisation’s head Mykola Kuleba said.

“For today, the Save Ukraine team has returned to Ukraine already 226 children who have been under the influence of Russian authorities since 24 February 2022.”
