9.51pm: Alphabet and YouTube should ban users pushing war propaganda as part of measures to stop disinformation after Russia's invasion of Ukraine, EU industry chief Thierry Breton told the chief executives of the two companies on Sunday.
On Saturday, Alphabet's Google barred Russia's state-owned media outlet RT and other channels from receiving money for ads on their websites, apps and YouTube videos, similar to a move by Facebook after the invasion of Ukraine, however Mr Breton has said the two companies should now go further.
"Freedom of expression does not cover war propaganda. For too long, content from Russia Today and other Russian state media has been amplified by algorithms and proposed as 'recommended content' to people who had never requested it," Mr Breton said.
"War propaganda should never be recommended content - what is more, it should have no place on online platforms at all. I count on the tech industry to take urgent and effective measures to counter disinformation."
9.37pm: Russian airline Aeroflot said on Sunday it would cancel all flights to European destinations until further notice after the decision by many countries to close their airspace in protest at Russia's invasion of Ukraine.
8.32pm: The United Nations Security Council on Sunday called for a rare emergency special session of the 193-member General Assembly on Russia's invasion of Ukraine, which will be held on Monday, as western allies step up a diplomatic campaign to isolate Moscow.
The vote by the 15-member council was procedural so Russia could not wield its veto. A resolution convening the General Assembly session was adopted with 11 yes votes. Russia voted no, while China, India and the United Arab Emirates abstained.
According to Ukraine's health ministry, 352 civilians, including 14 children, have been killed since the beginning of the Russia's invasion and 1,684 people, including 116 children, have been wounded.
8.19pm: EU foreign policy chief Josep Borrell has said Russia had clearly threatened a nuclear attack on countries supporting Ukraine after Russia's invasion, but this would not stop the bloc supporting the country.
"Just to mention the possibility of using nuclear weapons, it's such a gigantic irresponsibility that says a lot about the personality of who is doing that," Mr Borrell said on Sunday.
Speaking at a news conference in Brussels after a virtual meeting of EU foreign ministers on the crisis, he added the EU is worried the crisis could spill into neighbouring countries, including Moldova, Georgia and the Western Balkans.
Elsewhere, British prime minister Boris Johnson called a move by Russian president Vladimir Putin to put Russia's nuclear forces on high alert "a distraction from the reality of what's going on in Ukraine", the Press Association reported on Sunday.
Mr Johnson added Britain will send Ukraine a further £40 million (€47.9 million) in humanitarian aid and confirmed that any person settled in Britain would be able to bring their Ukrainian immediate family members to join them.
8.12pm: The highest UN court has confirmed that Ukraine has filed a suit against Russia, saying Russia's claim it invaded Ukraine to prevent a genocide is false and asking judges to order "provisional measures" to protect Ukraine.
Ukraine's president Volodymyr Zelensky had said earlier on Sunday he had filed the suit at the International Court of Justice, also known as the world court. In a statement, the court confirmed it has received Ukraine's complaint. It did not say when the case would be heard.
Meanwhile, EU foreign ministers have given support for fresh sanctions on Russia over its invasion of Ukraine to come into force by Monday, EU foreign policy chief Josep Borrell said on Sunday.
Mr Borrell said the ministers had reached a political agreement for a package of support for the Ukrainian armed forces, new sanctions and efforts to isolate Russia and to counter disinformation.
8pm: Russia, frustrated by early battlefield setbacks in Ukraine, could be shifting its strategy to siege warfare just as Russian president Vladimir Putin raises the risk of a catastrophic miscalculation by putting nuclear forces on heightened alert, a senior US defence official said on Sunday.
The US believes Russia has fired more than 350 missiles at Ukrainian targets so far, some hitting civilian infrastructure, the senior US defence official said, speaking on condition of anonymity. Still, it had so far mainly focused on military targets.
Citing a Russian offensive on the Ukrainian city of Chernihiv, north of Kyiv, the official cited early indications that Russia might be adopting siege tactics.
"It appears that they are adopting a siege mentality, which any student of military tactics and strategy will tell you, when you adopt siege tactics, it increases the likelihood of collateral damage," the official said.
7.55pm: Facebook's parent company Meta has restricted some accounts in Ukraine, including some accounts belonging to Russian state media organisations, at the request of the Ukrainian government, the company's head of global affairs Nick Clegg said in a tweet on Sunday.
"The Ukrainians have also suggested that we remove access to Facebook and Instagram in Russia. However, people in Russia are using FB and IG to protest and organise against the war and as a source of independent information," Mr Clegg said in another tweet.
He said the Russian government was already throttling Meta's platform to prevent these activities and that turning off its services would "silence important expression at a crucial time".
The war in Ukraine is devastating and our teams at Meta are taking a number of steps in response, detailed here: https://t.co/mqMsZ404ui

7.45pm: Swiss president Ignazio Cassis said on Sunday that it was "very probable" that neutral Switzerland would follow the European Union on Monday in sanctioning Russia and freezing Russian assets in the Alpine country.
Mr Cassis, interviewed on French-language Swiss public television, said that the seven-member Federal Council would meet on Monday and review recommendations by the departments of finance and economy.
Asked whether Switzerland, a major financial centre and commodities trading hub, would follow the EU in freezing Russian assets, he said: "It is very probable that the government will decide to do so tomorrow, but I cannot anticipate decisions not yet taken."

Elsewhere, England's Football Association has said the England soccer team will not play any matches against Russia for the foreseeable future to "whole-heartedly condemn the atrocities being committed by the Russian leadership" after its invasion of Ukraine. Other countries have also announced they will not play soccer matches against Russia.
FIFA has also said no international soccer matches will be played in Russia, and the Russian flag and anthem will be banned from any of their matches abroad. The governing body said the national team would not compete as Russia, but as the Football Union of Russia (RFU), and any games would be held with no fans on "neutral territory".
UPS and FedEx have also confirmed international shipments to Russia and Ukraine have been suspended until further notice.
6.45pm: The White House has called on China to condemn Russia's invasion of Ukraine on Sunday as Moscow's onslaught against its neighbour continued and Russian president Vladimir Putin put nuclear forces on high alert.
"This is not a time to stand on the sidelines. This is a time to be vocal and condemn the actions of President Putin and Russia invading a sovereign country," White House press secretary Jen Psaki said in an interview with MSNBC.
6pm: US banks are preparing for retaliatory cyberattacks after Western nations slapped a raft of stringent sanctions on Russia for invading Ukraine, cyber experts and executives said.
Tensions between Russia and the West escalated on Saturday as the United States and its allies moved to block some Russian banks from the SWIFT international payment system and placed curbs on the Russian central bank's international reserves.
Western governments have warned for weeks that the tensions could spark massive cyberattacks from Russia or its supporters. Some executives said the latest measures may be the trigger.
Also, the EU's executive said on Sunday that Europe was facing its biggest humanitarian crisis in many years following Russia's invasion of Ukraine, and the number of Ukrainians displaced by the strife could be more than 7 million.
"We are witnessing what could become the largest humanitarian crisis on our European continent in many, many years. The needs are growing as we speak," said Janez Lenarcic, European Commissioner for Humanitarian Aid and Crisis Management
"So for the humanitarian situation overall, the currently expected number of displaced Ukrainians is over 7 million," he told a news conference in Brussels after a special meeting of EU member states' interior ministers to discuss the crisis.
5.45pm: Hungary's interest is to stay out of the military conflict between Ukraine and Russia, Hungarian prime minister Viktor Orban said on Sunday, reiterating that Hungary would not send weapons to neighbouring Ukraine but would help all refugees.
Mr Orban told state television that his government would focus on Hungary's interests and make decisions that "allow us to stay out of this conflict and also that there should not be sanctions for which we have to pay the price in the end, even if we stay out of the conflict".
Elsewhere, Ukraine's foreign minister Dmytro Kuleba on Sunday said he had discussed new sanctions on Russia with the foreign ministers of the Group of Seven (G7) nations.
Meeting with @G7 foreign ministers. Partners stand ready to provide Ukraine with more practical means to defend ourselves. Defensive weapons, military equipment, and financial support for Ukraine are underway. We also discussed new painful sanctions to stop Putin’s war.
— Dmytro Kuleba (@DmytroKuleba) February 27, 2022
"Partners stand ready to provide Ukraine with more practical means to defend ourselves," Mr Kuleba wrote on Twitter. "Defensive weapons, military equipment, and financial support for Ukraine are underway. We also discussed new painful sanctions to stop Putin’s war."
He was not specific on what the sanctions could be, but Ukraine has called on its allies to impose more tough measures on Russia.
5.30pm: Ukraine's president Volodymyr Zelenskiy said on Sunday that he needed to use every opportunity to secure peace, as Ukraine was due to meet with Russia for peace talks.
"I do not really believe in the outcome of this meeting, but let them try so that later not a single citizen of Ukraine has any doubt that I, as president, tried to stop the war, when there was even a small, but still a chance," Mr Zelenskiy said.
Meanwhile, Russia's defence ministry said on Sunday that Russian soldiers had been killed and wounded during an offensive in Ukraine, but added its losses were far lower than those suffered by Ukraine without specifying a number, the Interfax news agency reported.
Since the start of what Russia calls its "special military operation" in Ukraine, armed forces have hit 1,067 Ukrainian military sites, Interfax cited the ministry as saying.
5pm: The European Commission aims to use €450 million of EU funds to finance arms deliveries to Ukraine, a Commission source told Reuters on Sunday.
An additional €50 million are meant to be spent on other equipment for Ukraine such as medical supplies, the source said.
Shortly before, European Union foreign policy chief Josep Borrell confirmed ministers from member states will on Sunday evening consider a proposal to use common funds to finance weapons, fuel and medical supplies for Ukraine.
Mr Borrell said Russia has begun targetting more civilian infrastructure in Ukraine, but warned that Russian president Vladimir Putin's war is not against Ukraine alone.
European Commission president Ursula von der Leyen also said the EU will also shut down airspace to Russian aircraft, seek to ban Russian state-owned media in the bloc and target Russian ally Belarus with sanctions.

3.55pm: Iskander missiles were launched from Belarus to Ukraine around 5pm (3pm Irish time), an adviser to Ukraine's interior minister said. It comes as Ukrainian and Russian officials are due to meet for talks at a venue on the Belarusian border with Ukraine.
3.50pm: Ukraine is running out of oxygen supplies that critically ill people need, the World Health Organisation said on Sunday, calling for safe passage for emergency imports as combat rages.
"The majority of hospitals could exhaust their oxygen reserves within the next 24 hours. Some have already run out. This puts thousands of lives at risk," it said. Oxygen is essential for patients with a range of conditions, including the 1,700 in hospital with Covid-19.
3.45pm: Russia denied on Sunday that talks with Ukraine had begun but said the two sides were arriving at the destination for negotiations, Interfax news agency quoted the Foreign Ministry as saying.
The negotiations could possibly offer some room to try to de-escalate the crisis after Russia invaded Ukraine from several directions. Earlier, an adviser to Ukraine's Interior Ministry said the talks had already begun.
3.35pm: In Ireland, Minister for Foreign Affairs Simon Coveney said he hopes the world is seeing the “first step” towards the ending of war ahead of talks between Ukrainian and Russian officials. However, he added the meeting will not be enough to deter the EU from imposing fresh sanctions.
Minister for Justice Helen McEntee meanwhile defended the decision to so far not expel the Russian ambassador to Ireland from the country, citing concerns for Irish citizens in Russia.
3.30pm: Russian president Vladimir Putin's move to put Russian forces on high alert is dangerous and irresponsible and adds to the Russian leader's aggressive pattern involving Ukraine, Nato Secretary General Jens Stoltenberg said on Sunday.
"This is dangerous rhetoric. This is a behaviour which is irresponsible. And of course when you combine this rhetoric with what they are doing on the ground in Ukraine - waging war against an independent, sovereign nation, conducting full-fledged invasion of Ukraine - this adds to the seriousness of the situation," Stoltenberg said on CNN's State of the Union programme.
3.25pm: Police detained more than 900 people at anti-war protests that occurred in 44 Russian cities on Sunday, raising the total since the start of Russia's invasion of Ukraine on February 24th to over 4,000, independent protest monitoring group OVD-Info said.
3.20pm: Russia dropped its preconditions for talks after suffering military setbacks, Ukraine's foreign minister said on Sunday, adding that Ukraine would attend the talks to listen to what Russia had to say. Dmytro Kuleba also told a briefing that Russian president Vladimir Putin's move to put nuclear forces on high alert was timed to put pressure on Ukraine during the negotiations.
3.15pm: The European Union needs to prepare for millions of Ukrainian refugees arriving in the bloc, EU Home Affairs Commissioner Ylva Johansson said on Sunday. "I think we need to prepare for millions," she told reporters in Brussels, adding she was in favour of activating the EU's temporary protection directive to provide shelter for those people coming to the EU.
3.12pm: Russian president Vladimir Putin's order to put Russian nuclear forces on high alert is part of a pattern of Moscow manufacturing threats to justify aggression, White House Press Secretary Jen Psaki said on Sunday. "We've seen him do this time and time again. At no point has Russia been under threat from Nato, has Russia been under threat from Ukraine."
2.58pm: Finland will allow neighbouring Estonia to offer Ukraine Soviet-origin howitzer field guns that it had previously bought from Finland but not been allowed to sell on, Defence Minister Antti Kaikkonen told reporters on Sunday.
Finland, which is not a Nato member, shares a long border with Russia and has previously maintained a policy of not allowing weapons to be exported to war zones. It will also directly donate 2,000 bulletproof vests, 2,000 helmets, 100 stretchers and equipment for two emergency medical care stations.
2.54pm: People fleeing war in Ukraine poured into central Europe on Sunday, with queues at border crossings stretching back for kilometres on the fourth day of a Russian invasion that has pushed nearly 400,000 people to seek safety abroad.
With men of conscription age prevented from leaving Ukraine, it is mostly women and children arriving at the border in eastern Poland, Slovakia and Hungary and in northern and northeastern Romania.
2.17pm: Ukrainian and Russian officials will meet for talks at a venue on the Belarusian border with Ukraine, the country's president Volodymyr Zelenskiy's office said on Sunday.
The talks, the first since Russia unleashed a full scale invasion of Ukraine last week, would be held without preconditions and are the result of a phone call between Zelenskiy and the Belarusian president, Zelenskiy said.
"We agreed that the Ukrainian delegation would meet with the Russian delegation without preconditions on the Ukrainian-Belarusian border, near the Pripyat River," he said in a statement.
1.30pm: Russian president Vladimir Putin ordered his military command to put Russia's deterrence forces - a reference to units which include nuclear arms - on high alert, citing aggressive statements by Nato leaders and economic sanctions against Moscow.
"As you can see, not only do Western countries take unfriendly measures against our country in the economic dimension - I mean the illegal sanctions that everyone knows about very well - but also the top officials of leading Nato countries allow themselves to make aggressive statements with regards to our country," Putin said on state television.
1.11pm: Israeli prime minister Naftali Bennett offered on Sunday to mediate an end to the Ukraine hostilties during a phone conversation with Russian president Vladimir Putin, the Kremlin said. The offer followed months of Ukrainian appeals to Israel to serve as intermediary. Israel has good ties with both Moscow and Kyiv, and Bennett has been publicly restrained in remarks about the fighting in Ukraine.
12.58pm: Russia's state communications regulator on Sunday said it had written to Alphabet Inc's Google and demanded that access to Russian media's YouTube channels be restored on Ukrainian territory. The regulator, Roskomnadzor, said it wanted all restrictions imposed on the Russian-language YouTube channels of media outlets RBC, TV Zvezda and Sputnik to be removed.
12.47pm: The mayor of Kyiv said on Sunday there were no Russian troops in the Ukrainian capital, which was holding its defence against attacks. Vitaly Klitschko said that in total 31 people died in the capital since the attacks started, including nine civilians, while 106 people had been injured. "Our military, law enforcement and territorial defence continue to detect and neutralize saboteurs," he wrote on his Telegram channel.
12.22pm: Ukraine has filed a suit against Russia at the highest UN court in The Hague for disputes between states, Ukrainian president Volodymyr Zelenskiy said on Sunday. It was unclear on precisely what grounds the case was being brought to the International Court of Justice (ICJ). A court official could not immediately be reached for comment.
"Ukraine has submitted its application against Russia to the ICJ," Zelenskiy said on Twitter. "Russia must be held accountable for manipulating the notion of genocide to justify aggression. We request an urgent decision ordering Russia to cease military activity now."
Earlier, Prosecutor General Iryna Venediktova said Ukraine would prove in a fair court that Russian president Vladimir Putin is "a main war criminal" of the 21st century.

"I will propose to (EU foreign) ministers to use the European Peace Facility for two emergency assistance measures," he said ahead of a virtual meeting to discuss fresh sanctions on Russia. "These aim to finance the supply of lethal material to the heroic Ukrainian army, which is fighting with fierce resistance against the Russian invaders and provide urgently needed non-lethal supplies, such as fuel."
10.50am: The UN nuclear watchdog IAEA's board of governors will hold an emergency meeting on Wednesday on the situation in Ukraine, diplomats said on Sunday.

We ask civilians not to go out."
Videos published by Anton Herashchenko, adviser to the interior minister, and Ukraine's state information agency showed several light military vehicles moving along a street and, separately, a burning tank. A witness in Kharkiv said Russian soldiers and armoured vehicles could be seen in different parts of the city and firing could be heard.

9.11am: Ukraine's president Volodymyr Zelenskiy urged the world on Sunday to scrap Russia's voting power at the UN Security Council and said Russian actions verged on "genocide." "This is terror. They are going to bomb our Ukrainian cities even more, they are going to kill our children even more subtly. This is the evil that has come to our land and must be destroyed," he said in a short video message. "Russia's criminal actions against Ukraine bear signs of genocide."
8.50am: A series of blasts was heard to the west of the Ukrainian capital Kyiv's centre on Sunday, minutes after air raid sirens sounded, a Reuters correspondent reported. Ukrainian media reported explosions and a gunfight in a nearby town.
According to Ukrainian news website Segodnya.ua, a bridge has been blown up near the town of Bucha west of Kyiv. It was unclear whether it had been bombed by Russian troops or destroyed by the Ukrainian side. Anton Herashchenko, an advisor to Ukraine's interior minister, said fighting was under way in Bucha with Russian forces that were trying to advance towards Kyiv.
8.30am: Moscow's decision to send a delegation to Belarus for talks is "propaganda", an adviser to Ukrainian president Volodymyr Zelenskiy told Reuters on Sunday, saying Ukraine wants only "real" negotiations with Russia over its military offensive, without ultimatums.
Earlier the Kremlin said the delegation had arrived in Gomel in neighbouring Belarus and was waiting for the Ukrainians. Zelenskiy rejected talks in Belarus, saying it was complicit in the invasion, but he left the door open for negotiations elsewhere.
Russian forces have attacked oil and gas facilities in Ukraine, sparking huge explosions, officials said on Sunday, as Western allies prepared new sanctions, including banishing key Russia banks from the main global payments system.
Ukrainian forces were holding off Russian troops advancing on the capital Kyiv, Ukrainian president Volodymyr Zelenskiy said as the biggest assault on a European state since World War Two entered its fourth day.
But Zelenskiy said the night had been brutal, with shelling of civilian infrastructure and attacks on everything, including ambulances.
Russian president Vladimir Putin launched what he called a special military operation on Thursday, ignoring weeks of Western warnings and saying the "neo-Nazis" ruling Ukraine threatened Russia's security - a charge Kyiv and Western governments say is baseless propaganda.
Offering a glimmer of hope for negotiations, the Kremlin said a delegation had arrived in neighbouring Belarus for talks and was waiting for the Ukrainians. But Zelenskiy rejected talks in Belarus, saying it was complicit in the invasion, but he left the door open for negotiations elsewhere.
Russian missiles found their mark overnight, including a strike that set an oil terminal ablaze in Vasylkiv, southwest of Kyiv, the town's mayor said. Blasts sent huge flames and billowing black smoke into the night sky, online posts showed.
"The enemy wants to destroy everything," said the mayor, Natalia Balasinovich.
Mushroom cloud
There was heavy fighting for Ukraine's second city, Kharkiv, in the northeast, where Russian troops blew up a natural gas pipeline, a Ukrainian state agency said.
That blast sent a mushroom cloud up into the darkness, though Ukraine's gas pipeline operator said the transit of Russian gas to Europe via Ukraine was going on as normal.
Russian troops later entered Kharkiv, interior ministry adviser Anton Herashchenko said on Telegram. Videos posted by him and a state agency showed several military vehicles moving on a street and, separately, a burning tank.
Russian-backed separatists in the eastern province of Luhansk said a Ukrainian missile had blown up an oil terminal in the town of Rovenky.
Reuters witnesses in Kyiv reported occasional blasts and gunfire through the night, then three blasts after air raid sirens went off shortly before 9am (6am Irish time).
Ukrainian leaders were defiant.
"We have withstood and are successfully repelling enemy attacks. The fighting goes on," Zelenskiy said in a video message from the streets of Kyiv posted on his social media.
A US defence official said Ukraine's forces were putting up "very determined resistance" to Russia's air, land and sea advance, which has sent hundreds of thousands of Ukrainians fleeing westwards, clogging major highways and railway lines.
Bad for business
The United States and its allies have imposed a range of sanctions on Russia in response to an assault that threatens to upend Europe's post-Cold War order.
On Saturday, they moved to block certain Russian banks' access to the Swift international payment system. They also said they would impose restrictions on Russia's central bank to limit its ability to support the rouble and finance Putin's war effort.
"We are resolved to continue imposing costs on Russia that will further isolate Russia from the international financial system and our economies," said a statement from the United States, France, Germany, Canada, Italy, Britain and the European Commission.
After initially shying away from such a move largely because of concern about the impact on their economies, the allies said they committed to "ensuring that selected Russian banks are removed from the Swift messaging system."
They did not name the banks that would be expelled, but an EU diplomat said some 70 per cent of the Russian banking market would be affected.
The decision - which the French finance minister had called a "financial nuclear weapon" because of the damage it would inflict on the Russian economy - deals a blow to Russia's trade and makes it harder for its companies to do business.
Swift, a secure messaging network that facilitates rapid cross-border payments, said it was preparing to implement the measures.
Sanctions on Russia's central bank could limit Putin's use of his more than $630 billion (€559 billion) in international reserves, widely seen as insulating Russia from some economic harm.
Google barred Russia's state-owned media outlet RT and other channels from receiving money for ads on their websites, apps and YouTube videos, similar to move Facebook made.
'Advancing'
Earlier, the Kremlin said its troops were advancing again "in all directions" after Putin ordered a pause on Friday. Ukraine's government said there had been no pause.
A Ukrainian presidential adviser said about 3,500 Russian soldiers had been killed or wounded. Western officials have said intelligence showed Russia suffering higher casualties than expected.
Russia has not released casualty figures and it was impossible to verify tolls or the precise picture on the ground.
A United Nations relief agency said as of Saturday evening at least 64 civilians had been killed among 240 civilian casualties, more than 160,000 people had been internally displaced and more than 116,000 had fled to neighbouring countries.
Ukraine, a democratic nation of 44 million people, won independence from Moscow in 1991 after the fall of the Soviet Union and wants to join Nato and the EU, goals Russia opposes.
Putin has said he must eliminate what he calls a serious threat to his country from its smaller neighbour, accusing it of genocide against Russian-speakers in eastern Ukraine - something Kyiv and its Western allies reject as a lie.
