A Ukrainian official has called for the “liquidation” of Iranian weaponry factories and the arrest of their suppliers, as Kyiv accuses Tehran of planning to supply more arms to Russia.

Writing on Twitter on Saturday, Ukrainian presidential aide Mykhailo Podolyak said Iran “blatantly humiliates the institution of international sanctions”, and called for the destruction of Iranian weapon factories.

Volodymyr Zelensky has thanked US President Joe Biden for inviting him to the US.

The Ukrainian president visited Washington, US where he met with Mr Biden and addressed Congress in his first trip since Russia invaded Ukraine in February.

In a Tweet, he wrote: “This visit showed our countries stand together on the side of good, democracy and justice.”

President Vladimir Putin has told Russia’s defence industry chiefs to up their game to ensure they have enough weaponry needed to fight the war in Ukraine.

“The most important task of our military-industrial complex is to provide our units and frontline forces with everything they need,” he said on Friday (23 December).

“Weapons, equipment, ammunition, and gear in the necessary quantities and of the right quality in the shortest possible timeframes.

“It’s also important to perfect and significantly improve the technical characteristics of weapons and equipment for our fighters based on the combat experience we have gained,” he added.

Ukrainian president Volodymyr Zelensky has wished the UK a Merry Christmas and thanked the British people for their support.

Responding to a tweet posted by Rishi Sunak, he said that Ukrainians “feel the light and the warmth” of British hearts and, together, we would “defeat evil and restore peace in Ukraine, Europe, and the world”.

Russia is cutting down on missile attacks in Ukraine due to shortages, says the UK’s Ministry of Defence.

In their latest update shared on 24 December, they said: “Russia has likely limited its long-range missile strikes against Ukrainian infrastructure to around once a week due to the limited availability of cruise missiles.

“Similarly, Russia is unlikely to have increased its stockpile of artillery munitions enough to enable large-scale offensive operations,” they added.

Ukraine will be opening new embassies in 10 African countries, said president Volodymyr Zelensky.

Speaking at a conference on 23 December, the Ukrainian president said that he plans to increase the country’s presence in Africa by opening new embassies and strengthening trade ties.

He added that there were also plans to develop a “Ukraine-Africa trade house” with offices in the capitals of “the most promising countries” across Africa.

Olha Komarnytska who lives in Birmingham with her children – Mia, 15, and Volodymyr, 13 – are also set to experience their first Christmas in the UK, alongside their host family.

They arrived in the UK from western Ukraine in May of this year.

“We usually celebrate Christmas in January but a think of lot of Ukrainians will celebrate Christmas in December this year because Russians celebrate Christmas in January and it’s not very good for us because we are fighting with Russia”, Ms Komarnytska, a 42-year-old cleaner said.

She said that on December 25, the group are to go to Church together, followed by a Christmas dinner, which will include traditional British and Ukrainian food staples.

“I plan to make cabbage with rice, meat carrot and onions and a Ukrainian salad with potato, carrot, meat, onions and cucumber,” she added.

The family have already gotten into the Christmas spirit by attending a party hosted by Centrala, an art space in Birmingham dedicated to promoting Central and Eastern European art and culture, on December 19 – Saint Nicholas Day.

“It was amazing and all the children there were very happy – they received a lot of presents and they saw Santa and heard Ukrainian music”, she said.

“My son was sadly not at the party as he was ill but my daughter was really happy when she went.”

Several people from the family will be absent from the dinner – Mrs Komarnytska’s husband Taras, her mother and father, Anna and Vasyl and brothers Dmytro and Vasyl.

“We’re so sad because we can’t be with our family because my husband stayed in Ukraine and my mum, dad and brothers all stayed in Ukraine and we can’t celebrate Christmas with them”, she said,

“It’s not good, we are not happy – but the situation is very bad because of the war happening in Ukraine and there is a bad situation with electricity where many don’t have any.”

This time of the year is also tainted with sadness since Ms Chebizhak would usually spend Christmas with her family back in Ukraine, of which the exact location details cannot be mentioned for safety reasons.

“Usually we have traditions where my mum (Tetiana) will always make 12 dishes which symbolise the 12 months of the year and we would make a wish on Christmas Eve and go to bed and it should come true”, she said.

Ms Chebizhak added that her parents are okay, but that her mother did not put up a Christmas tree due to the ongoing war.

“My sister Anna also used to live not too far from them and she also left to go to Greece with her two children, so they are alone and she doesn’t have any grandchildren nearby”, she added.

“My mum and dad might sit down together and watch some movies or listen to the national anthem of Ukraine and we’ll have a call, but they are coping and doing great despite it not being a good situation.”

As the pair look forward to 2023, Ms Chebizhak said she “dreams of peace in our country”.

“We really hope the war’s over and we can return to see Kolya’s dad as he misses him very much and is still in the Vinnytska region in Ukraine.”

Ukrainians celebrating their first Christmases in the UK have been busy writing letters to Santa Claus and planning out traditional dishes they plan to make on the big day, amid hopes for peace and being reunited with their loved ones back home in 2023.

Despite usually celebrating Christmas on January 7 – as determined by the Orthodox Church – Kateryna Chebizhak, 34, who works as a telephone interpreter, and her seven-year-old son Kolya, are planning on spending December 25 with friends who live near them in Enfield, North London.

“We have friends here that live just next door and we will meet to celebrate”, Ms Chebizhak said.

“I have some presents for Kolya and we will have a nice walk, we might do some arts and crafts and play Uno.”

The pair came to the UK in April after fleeing Kyiv, following short stays in Poland and Germany.

She added that when she told her son that in the UK children usually receive Christmas presents on December 25, he began making a list.

“Usually in Ukraine, we just get presents under the Christmas Tree in the New Year, but [in the UK] it works differently”, she said.

“Now’s he waiting for his two presents and he’s really excited.

“As it is the school holidays, he has been writing letters to Santa Claus.”

The charities the money will be donated to are: Hospitallers, a Ukrainian voluntary paramedic organisation; Kharpp, which helps refugees in Ukraine and as they arrive in Poland; Livyj Bereh, which provides supplies and the reconstruction of houses and schools; Kyiv Volunteer, which provides aid and feeds civilians; and Vostok SOS who help victims of the conflict in eastern Ukraine.

The band also encouraged people to donate to the groups directly, adding: “Season’s Greetings to you all and Slava Ukraini.”

Guitarist and vocalist Gilmour, who has a Ukrainian daughter-in-law and grandchildren, previously said the group had been “feeling the fury and the frustration of this vile act of an independent, peaceful democratic country being invaded and having its people murdered by one of the world’s major powers”.

The musician, 76, explained when the charity song was announced that he had approached Khlyvnyuk after seeing the video he shared to Instagram in which he is heard singing a patriotic Ukrainian protest song, The Red Viburnum In The Meadow, as he thought it was a “powerful moment” which he wanted to put music to.

The title of the Pink Floyd track is taken from the last line of the song.

The video for the new song has been filmed by director and screenwriter Mat Whitecross and the cover artwork for the single features a painting of a sunflower, the national flower of Ukraine, by Cuban artist Yosan Leon.

The flower is said to be a reference to the woman who confronted Russian soldiers telling them to take seeds from her and to carry them in their pockets so when they died, sunflowers would grow.
