We're about to end our coverage of the latest on Ukraine. But before we go, here's a summary of what's happened today, as we approach the first anniversary of Russia's invasion of Ukraine:

• The UN General Assembly has voted overwhelmingly to condemn Russia's invasion of Ukraine and call for peace as soon as possible
• It comes as Ukraine's military intelligence warns that it is expecting Russia to carry out attacks tomorrow, on the anniversary of the war, with schools closed and people encouraged to work from home
• Over in Russia, President Vladimir Putin declared Moscow's intention of developing its arsenal of nuclear weapons in the coming year during a speech to mark Defender of the Fatherland day - a national holiday celebrating the armed forces
• And in Vienna, a large number of delegates staged a walkout at the Organization for Security and Co-operation in Europe (OSCE)'s parliamentary assembly over Austria's decision to give visas to Russian lawmakers

That's it from us until tomorrow. The live page was edited by Andrew Humphrey, Sam Hancock and Robert Greenall. Our writers were Anna Boyd, Adam Durbin, Thomas Mackintosh, Laura Gozzi, Alys Davies and James Harness.

“I want to be with my people,” 23-year-old Angie from Uzhhorod, Ukraine, told me, standing alone, draped in a blue and yellow flag, in drizzly central London.

A crowd of around 2,000 people, mainly Ukrainian refugees, convened here in Trafalgar Square to watch a vigil to mark the one-year anniversary of the Russian invasion of their country.

Angie fled Ukraine for Berlin, Germany last year, but moved to London in November because she felt that some political groups in the country were siding with Putin’s “fascism”.

Angie told me she feels safer in London, because of the UK’s strong support for Ukraine.

The event opened with a Ukrainian folk music performance, prompting a soft, heartfelt chorus from the audience.

I watched as one woman’s eyes welled up, as she squeezed her son tighter to her chest.

The biggest act of the night was Antytila, a Ukrainian rock group that shot to fame last year after they collaborated with UK pop-singer Ed Sheeran on his song 2step.

Lead singer, Taras Topolia, who has served on the frontline as a medic, told me it was “highly emotional” performing for exiled Ukrainians in London, who have “started their lives from zero”.

But steeling his nerve, he turned to our camera.

“Ukraine will win”, said Topolia, “It will get this victory, it’s only a matter of time."

More on the UN vote now.

While the resolution was passed overwhelmingly by the majority of nations, there were some notable abstentions.

China, who has in recent days demonstrated its solidarity with Russia, abstained from the vote - the fourth time it has done so in votes relating to Ukraine. India and South Africa were also among the 32 nations to abstain.

Predictably Russia, along with six other nations, voted against the resolution. Among the others were Mali and Eritrea, who had previously abstained in other votes on Ukraine.

The United Nations General Assembly has voted overwhelmingly to approve a resolution condemning Russia's invasion and calling for the withdrawal of troops from Ukraine and a halt to fighting.

The resolution was approved with 141 nations voting in favour, 32 abstaining and seven voting against - a similar outcome to previous resolutions on Ukraine.

Britain was the first country to pledge modern western battle tanks to Ukraine.

Now, Kyiv's soldiers are in the UK learning how to operate them.

Some, like Sasha, are battle hardened. He's been fighting in eastern Ukraine.

But he is swapping his old Russian T-80 tank for the British Army's Challenger 2.

His friend, Grisha, was just driving tractors until a few months ago.

Now they're both learning to drive a 60-tonne tank - much heavier and more sophisticated than anything they've been used to.

The British Army's Challenger 2 may be more than 20 years old, but both Sasha and Grisha see it as a vast improvement on Ukraine's older and lighter Soviet-era tanks.

Sasha raves about its suspension and manoeuvrability, and easy access to the engine. The driver is also the mechanic.

But he particularly likes the fact that inside there's a very British piece of kit to heat water for cups of tea. He says his old tank didn't have such creature comforts.

Grisha's focused on their main purpose. He says Western tanks, like the Challenger 2, are exactly the kinds of weapons Ukraine needs to win this war.

The US government will announce "sweeping" new sanctions against Russia on Friday, the first anniversary of the full-scale invasion of Ukraine.

President Joe Biden's press secretary Karine Jean-Pierre told reporters earlier that the US president will also meet his Ukrainian counterpart Volodymr Zelensky and G7 leaders virtually on Friday.

Jean-Pierre did not offer much detail on the nature of these sanctions, but did say they would be imposed "against key sectors that generate revenue" for Russian President Vladimir Putin.

China's representative at the UN General Assembly, which is meeting in New York today, has said sending weapons will not lead to peace in Ukraine.

China's deputy UN Ambassador Dai Bing said that a year into the war in Ukraine, "brutal facts offer an ample proof that sending weapons will not bring peace".

"Adding fuel to the fire will only exacerbate tensions," he said in comments cited by Reuters.

"Prolonging and expanding the conflict will only make ordinary people pay an even heftier price," he added.

His comments could be viewed as criticism of Western powers' provision of weapons to Ukraine.

They come after Nato said it had seen signs China is planning on supplying weapons to Russia.

The Paris landmark was lit up in the colours of Ukraine's flag to mark one year of the conflict.

Ukraine's Ambassador to France Vadym Omelchenko was among guests invited to the ceremony.

One year into the war, Russia has failed to take control in Ukraine, its army has suffered heavy losses and Russian President Putin has not gained as much ground as he hoped.

But now as spring approaches, Russia's army has been bolstered by hundreds of thousands of new conscripts, with intelligence reports suggesting Russia is gearing up for a renewed land offensive. So what's Putin's plan now?

Speaking to the BBC's Inquiry programme, Gustav Gressle of the European Council on Foreign Relations says the spring offensive will likely involve an increase in attacks and operations in eastern Ukraine, including the Donbas region.

But with many of Russia's soldiers inexperienced, Gressle says they may struggle to make breakthroughs.

Earlier we reported a mass-walkout of delegates over the presence of a Russian contingent at a security conference in Vienna. At the same session a Latvian MP expressed his fury that they had been permitted to participate.

Rihards Kols described their presence at the Organization for Security and Co-operation in Europe (OSCE) parliamentary session as the "elephant in the room", adding it was a "disgrace" they were allowed to take part.

He said he had a message for the Russians present, going on to quote the swear words famously used by Ukrainian troops defending Zmiinyi (Snake) Island in the Black Sea at the start of the Russian invasion, offered in response to suggestions they should surrender.

He also accused some of the Russians present of being war criminals themselves.

Austria's decision to give visas to the delegation - some of whom are under EU sanctions - has caused controversy for weeks.

The Austrian government says it was obliged to do so under international law because the OSCE has its headquarters there.

Ukraine's President Volodymyr Zelensky has said he has not seen any Chinese plan for bringing the war to an end, but it would be "desirable" for Ukrainian and Chinese representatives to meet.

Beijing - an ally of Russia - has indicated that it will be releasing a "peace plan" for Ukraine.

Speaking during a news conference in Kyiv today alongside Spanish Prime Minister Pedro Sanchez, Zelensky said: "We would like to meet with China."

"This is in the interests of Ukraine today," he added in comments quoted by Reuters.

The Eiffel Tower in Paris has been lit with the colours of the Ukrainian flag, as a demonstration of solidarity on the eve of the first anniversary of Russia's full-scale invasion.

Vladislav, who has been speaking to our colleagues at BBC Radio 5 Live since the war in Ukraine began, has been reflecting on the past year.

Asked what he believes Russia has been trying to achieve since it launched its full-scale invasion last February, Vladislav says President Vladimir Putin is trying to make the Ukrainian people " weary and tired".

"But no-one is feeling tired… we will do this as long as it’s needed,” he says.

Vladislav adds he believes war has "allowed Ukrainians to identify their own" and that "we will fight to liberate our country as long as it takes".

Poland has started to fortify its border with the Russian exclave of Kaliningrad, the country's Defence Minister Mariusz Blaszczak says.

Posting four photographs on his Twitter feed showing steel and concrete anti-tank obstacles, he says Poland has "started a preventive expansion of security measures" on the border with the Russian region.

Separated from Russia proper, Kaliningrad is bordered only by Poland and Lithuania, both members of the EU and Nato.

In November, the Polish military began laying out a temporary 2.5m (8ft) high razor wire fence along its 232km (144 miles) border with Kaliningrad, amid concerns of a new migration wave after Moscow starting allowing direct flights into the Russian exclave from Turkey and the Middle East.

Last year Poland erected a 5.5m-high steel pole fence along part of its border with Belarus after a huge rise in migrant crossings of people from the Middle East, Africa and Asia.

Poland and the European Commission accused the Belarusian authorities of creating a migrant crisis by allowing people to enter Belarus on a tourist visa and assisting them to illegally cross the border (not through official border crossings).

Warsaw said Belarus, with Moscow’s backing, launched what it called “hybrid warfare” to destabilise the EU.

Human rights groups accuse the Polish and Lithuanian border guard of illegally pushing back migrants into Belarus.

Under EU law, migrants seeking international protection must be given access to asylum procedures even if they cross a border illegally.

Russia’s invasion began with dozens of missile strikes on cities all over Ukraine before dawn one year ago.

Within a few weeks Russian troops were in control of large areas of Ukraine.

They had advanced to the suburbs of Kyiv, the capital, and gained control of much of the north-east of the country around Sumy.

Russian forces were bombarding Kharkiv, and they had taken territory in the east and south as far as Kherson and surrounded the port city of Mariupol.

By October the picture had changed dramatically. Having failed to take Kyiv, Russia withdrew from the north.

And Ukraine had its first major success, pushing Russia back from Kharkiv and counter-attacking around Kherson.

One year since the invasion, Ukraine is in control of Kherson and fighting is concentrated in the east, with the heaviest around the town of Bakhmut.

Nato Secretary General Jens Stoltenberg says he has seen signs that China may be planning to supply Russia with weapons.

In an interview with Reuters, he says that though Nato has not seen any actual supplies of weapons from China to Russia yet, there are indications China may be planning to do so.

Stoltenberg adds that China "should not support Russia's illegal war", which he calls a "blatant violation of international law" as well as the UN Charter - which China is subject to as a member of the UN Security Council.

He says the basic principle of the Charter is that countries should "respect the integrity of other nations and not to march in and invade another country with hundreds of thousands of troops and of course, China should not be part of that".

A large number of delegates have staged a walkout during a Russian address at a parliamentary session of the Organisation for Security and Cooperation in Europe (OSCE) in Vienna.

Some held up Ukrainian flags, while the Ukrainian and Lithuanian delegations boycotted the meeting.

They were protesting against the presence of a Russian delegation at the session of the OSCE’s Parliamentary Assembly, which began a day before the first anniversary of Russia’s invasion of Ukraine.

Austria’s decision to give visas to the delegation of Russian parliamentarians, including some who are under EU sanctions, has caused controversy for weeks.

Last year the UK and Poland refused visas to Russians attending OSCE meetings they hosted.

But the Austrian government said it was obliged under international law to grant entry to the delegates because the OSCE has its headquarters in Vienna.

Austrian Foreign Minister Alexander Schallenberg told the Austrian broadcaster ORF that "the date is very unfortunate".

"But at the same time, we must not disregard the fact that we need platforms. The OSCE has never been an organisation of like-minded people," he said.

Olena, a Ukrainian woman who has been living in the country with her children throughout the war, has been speaking to our colleagues at BBC Radio 5 Live since the Russian invasion began last February.

Now on the eve of the first anniversary of the beginning of the war, she says: "We celebrate how strong we are, this pain will be with us forever, but not in vain, it will be our victory."

If you're just joining us, or need a recap, here's a rundown of what's happening in Ukraine and beyond - just a day before the year anniversary of Russia's full-scale attack on Ukraine.

Vladimir Putin remains defiant... as Russia celebrates Defender of the Fatherland day, a public holiday in the country. In a speech, he declared Moscow's intention to develop its arsenal of nuclear weapons this year.

The UN General Assembly... is due to vote later today on a resolution calling for Russia to leave Ukraine with immediate effect. The vote isn't legally binding but does hold political weight.

Ukraine's military intelligence chief Kyrylo Budanov... says he expects Russia to carry out attacks tomorrow, on the anniversary, but it would be “nothing extraordinary” for his country. Ukrainians all across the country have been warned to expect Russian attacks to tie in with the date.

President Volodymyr Zelensky... took to Telegram earlier to reflect on the last 12 months, insisting Ukraine will hold Russia to account for "all the terror, all the killings, all the torture". He also said, as is customary in his speeches, that Ukraine will prevail.

Another world leader visited Ukraine... with Spain's PM Pedro Sanchez becoming the next person on Zelensky's list to fulfil his promise of completing a "diplomatic marathon" to secure support for his country.

In the UK... Defence Secretary Ben Wallace has suggested the war in Ukraine could go on for another year, saying Putin has complete disregard for his own soldiers.

Arrests were made earlier... after protesters used yellow and blue paint to cover a road outside the Russian embassy in London, eventually creating a giant Ukraine flag.

Russia will continue to develop its arsenal of nuclear weapons this year, President Vladimir Putin has declared in a video address for Defender of the Fatherland Day - Russia's annual public holiday commemorating its war dead.

Focusing on three hypersonic missile systems capable of carrying nuclear warheads, Putin says the Sarmat missile system (a long-range weapon also colourfully known as the 'Satan II') "will be put on combat duty" for the first time.

He added that full production of the air-launched Kinzhal missile system will continue this year, while the sea-launched Tsirkon system will begin mass-deployment.

In his speech, Putin also said Russia will continue to supply "advanced equipment to our troops, including new strike systems, reconnaissance and communications equipment, drones and artillery systems".

Standing in a room flanked by two flags, the Russian leader congratulated servicemen, volunteers and mobilised citizens, and repeated his unfounded claims Russiawas fighting "neo-Nazism that has taken root in Ukraine, protecting our people in our historical lands" - a rhetorical cornerstone of the Kremlin's propaganda to justify their invasion.
