Ordinary Russian people are already feeling the hit of Western sanctions targeting their banks, which is making it harder for them to acess money.

Here are some everyday ways it's affected people, according to Russian locals who spoke with the BBC:

• People can't afford mortgage repayments after interest rates doubled on Monday to 20%
• People have lost payment methods because their banks have been cut off from Visa and Mastercard, and subsequently Apple Pay and Google Pay
• People are scrambling to get US dollars out - leading to scenes of long queues at ATMs
• "When the operation in Donbas started I went to the ATM and withdrew the savings I had in Sberbank in dollars. Now I literally keep them under my pillow," said one man in his 30s in Moscow

• At the start of 2022 one dollar traded for about 75 roubles and a euro for 80. But the war has helped set new records - at one point on Monday a dollar cost 113 roubles and a euro, 127.

The Russian invasion is drawing mixed reactions in China's tightly-controlled online environment.

Some social media users have heaped praise on Russian president Vladimir Putin, labelling him as "awesome" and perceiving his actions as a way to counter US influence in the world.

"I support Russia, oppose US. That's all I wanna say," writes a commenter.

"America always wants to create mess in the world!" says another.

However, there have been critics that still manage to make their voices heard despite stringent censorship conditions in the country.

Over the weekend, five prominent Chinese academics wrote an open letter denouncing Russia's actions.

"This is an invasion. As the Chinese saying goes: you cannot call a deer a horse," said historian Xu Guoqi, according to a Reuters report.

Hours after the letter was posted it was taken down by internet censors.

It's difficult to get a true sense of how many people in China are calling for peace, when its unclear how many such posts have been censored - and how many posts criticising the US have been promoted.

Air sirens are currently blaring as morning begins in Ukraine.

In addition to Kyiv, the alarms are ringing in the western cities of Ternopil, Vinnytsia, Rivne, as well as the central cities of Cherkasy and Kropyvnytskyi, according to the BBC's Ukrainian service.

It's just after six in the morning in Kyiv, as day six of the Russian invasion of Ukraine begins.

Here's what you need to know:

• The Russian army continues its steady advance on Kyiv, with satellite images spotting an armoured convoy that appears to be about 40 miles long (65km)
• Russian troops have reportedly begun a ground assault on the southern city of Kherson, witnesses say
• More explosions were heard overnight in cities throughout the country
• Officials say dozens of civilians have been killed, but the numbers are thought to be an underestimate

• Envoys for Russia and Ukraine held peace talks at the Belarus border on Monday, but reached no agreements other than a commitment to meet again in the coming days
• Even as peace talks were in progress, the Russians continued shelling cities and towns including Kharkiv, Kyiv, and Chernihiv, according to Ukraine's president
• President Volodymyr Zelensky called for a no fly zone over his country, and for Russia to be removed as permanent member of the UN Security Council
• Ukraine submitted a formal request to join the European Union, and at least eight other EU countries have already signalled their support for the measure

The Chinese embassy in Ukraine is now starting to evacuate its citizens.

The embassy said the first organised group left yesterday, with state media saying these were Chinese students from Kyiv heading to Moldova.

The fact that China is only evacuating its citizens now could mean several things.

One possibility is that Beijing initially felt it was important not to upset Russia prematurely. Another, that China might have thought Russia would take Ukraine so quickly it would not necessitate people leaving.

And another more worrying possibility is that China has calculated that Russia's invasion is about to get much worse.

Up to 70 Ukrainian soldiers have been killed in a Russian artillery strike on the north-eastern city of Okhtyrka on Sunday, according to a local official.

Dmytro Zhyvytskyi, the head of the Sumy region's state administration, says the strike destroyed a Ukrainian military unit, and rescuers and volunteers have been working to retrieve the bodies from the rubble.

"Many people have died. Currently, places are being prepared in the cemetery for about 70 dead Ukrainian soldiers," Zhyvytskyi posted on Telegram.

"But the enemy also gets what he deserves," he added, saying there were "a lot of Russian bodies" in the city, which are now being given to the Red Cross. His claims have not been independently verified.

US lawmakers leaving a classified briefing in Washington are continuing to speak out about what they've learned.

Connecticut Senator Chris Murphy tweeted that the briefing confirmed that the "Russians have fallen behind on their timeline" for the invasion.

Virginia's Senator Mark Warner added that the Ukrainian leadership had put a stiff resistance so far.

Mastercard has said that it has blocked multiple transactions from its payment gateway as a result of sanctions imposed on Russia over its invasion of Ukraine.

The news comes as the US, along with the EU, UK and Canada, said they would take action against Russia by closing off Russian banks from the Swift international payments system and prevent Russia's central bank from deploying its foreign reserves to cushion the impact of sanctions.

When the siren wailed in Dnipro, we headed beneath ground into a nuclear bunker built in the Cold War. Decades later, it’s sheltering hundreds of people in modern-day Ukraine as Vladimir Putin’s war escalates.

The bunker was originally for factory workers but the plant itself was abandoned long ago. Down a single flight of steps and beyond a thick metal door, the walls are plastered with instruction posters on how to wear a gas mask or protective suit.

Alongside a sign detailing "the lessons of Chernobyl", volunteers have piled biscuits, packs of tea and preserves around a Soviet TV.

The cave-like rooms, lined with heavy metal bunk beds, can take around 700 people.

Alina and Yuri spent all last night down here. They admit they were scared when they first heard the siren, but half a dozen air raids later they’re more used to the drill.

They keep a grab bag by the door ready for the 800 metre dash from their flat.

Alina said she had no idea why Russian had attacked.

‘They say they want to protect us. But what from? We are just hiding now. We didn’t need their protection,’ she said.

The narrative of war isn't decided on the battlefield, but online.

Is Russia limiting access to social media?

How is Silicon Valley addressing disinformation?

Is the US preparing for a cyber-attack?

The BBC's James Clayton explains how war in Ukraine is being fought on the tech battlefront.

Pictures from the separatist-controlled region of Donetsk in eastern Ukraine show destruction that officials there say was caused by Ukrainian shelling.

Rubble from homes in the Russian-speaking province is seen on the streets alongside burnt-out cars.

Also on Monday, the community in the town of Horlivka, Donetsk, held funerals for two school teachers who died during an artillery assault.

Australia will contribute A$70m ($50m; £38m) in military support to Ukraine.

Prime Minister Scott Morrison said on Tuesday the money will go towards lethal as well as non-lethal aid.

"We are talking missiles, ammunition, we are talking supporting them in their defence of their own homeland in Ukraine," he said.

He declined to elaborate on specifics, saying he did not want "to give Russia a heads up".

Morrison says his government will also commit A$35m in humanitarian aid to Ukraine.

US lawmakers have received classified briefings on the situation in Ukraine from top defence and intelligence officials.

The intelligence reportedly included possible timelines for the fall of Kyiv and other Ukrainian cities.

"The worst is yet to come militarily," Republican Senator Lindsey Graham said as he left the briefing room.

One unnamed lawmaker told CNN the timeline officials laid out for the coming days was "alarming".

Senator Chris Murphy, a Connecticut Democrat, wrote on Twitter: "The fight for Kiev will be long and bloody."

Murphy said Western nations would not only freeze but also seize the assets of the Russian president and top oligarchs, which he said was "likely a further step than Putin’s inner circle anticipated".

The war in Ukraine is marking a turning point in the world order, not least by showing off the power and use of digital currencies.

Bitcoin, the world’s largest cryptocurrency, rose more than 15% to over $43,000 at one stage.

Ethereum jumped by more than 10%.

It comes amid reports that Binance, the biggest crypto exchange, will not be blocking the accounts of Russian users despite calls to do so.

On Sunday, Ukraine's Minister of Digital Transformation Mykhailo Fedorov had called on all major crypto exchanges to block Russian users.

"It's crucial to freeze not only the addresses linked to Russian and Belarusian politicians, but also to sabotage ordinary users,” he wrote on Twitter.

The worry is that, without access to the global financial system, Russia will try to use cryptocurrency to get around Western sanctions.

Meanwhile, in Ukraine millions in Bitcoin have poured in from donors.

"My God, another one!" says a stunned resident watching a column of Russian tanks take over the southern Ukrainian port city of Berdyansk on Sunday.

"I think there's been about 15 of them so far. They're innumerable... OK, maybe a dozen. So they've stopped to talk."

Mariupol, about 85km to the east of Berdyansk, is still under a Russian siege but has not yet fallen, according to reports.

A shipment of Starlink terminals, which allow internet users to access satellite-based internet from SpaceX, have arrived in Ukraine, according to an official.

Ukraine's vice-prime minister, Mykhailo Fedorov, who is also Ukraine's minister of digital transformation, shared the news in a tweet thanking SpaceX founder Elon Musk.

"You are most welcome," Musk tweeted back.

It comes after Fedorov tweeted to Musk, requesting the devices to circumvent internet outages in Ukraine.

SpaceX hopes to eventually deploy thousands of the satellites into low-earth orbit, to allow people in remote or isolated places to access the internet.

Ukraine officials say Russian troops have begun an assault on Kherson, a city in the south between Mykolaiv and New Kakhovka.

"According to eyewitnesses, the enemy is advancing from the airport to the Nikolaev highway and a ring near the cold storage plant", Ukraine's State Service for Special Communications and Information Protection reported on its Telegram channel in the past hour.

Earlier, BBC Ukraine reported that powerful explosions were heard near the Kherson airport.

Kherson's regional state administration also wrote on Facebook that the city is surrounded by Russian troops but not captured.

The city's mayor has also said that the Russian army had set up checkpoints at the entrances to the city.

"It is difficult to say how the situation will develop further," mayor Igor Kolykhaye wrote on Facebook, adding: "Kherson was and remains Ukrainian!"

"I ask each of you to remain calm and prudent. Do not go outside during the curfew. Do not enter into aggressive negotiations with anyone and do not provoke the enemy to conflict," the mayor said.

Ukraine's military is saying that Russian troops have resumed their attack on the capital Kyiv.

"The situation around Kyiv remains tense," warns a Facebook post from the General Staff of the Armed Forces of Ukraine.

"Despite the fact that the enemy is losing offensive potential, he continues to inflict fire on military and civilian targets," it reads.

The post claims that Russia "plans to join with the highly trained military units of the Republic of Belarus" and also to use Belarusian airspace for its military air traffic.

Earlier on Monday, the US state department said it had not yet seen any indications of Belarusian troop movements.

Over the weekend, Russia's leader put his country's nuclear forces on "special" alert.

But nuclear arms researcher Pavel Podvig says the move is a signal to the US not to interfere in Ukraine.

"The very fact nuclear weapons have become embroiled in this already complex situation is worrying," he told BBC World News.

But he noted "it is not as negative a development as it would appear".

On Monday Kharkiv, Ukraine’s second-largest city, was attacked by Russian rocket launchers. Dozens of civilians are thought to have been killed. The mayor, Igor Terekhov, condemned the attack, saying that residential areas were targeted.

Several women from Kharkiv spoke to the BBC about their lives being turned upside down by the bombardment.

“We have been hiding in the basement for four days. And it is only getting worse. We are running out of food,” said Alena. She and her two boys haven’t been able to leave the house.

Svetlana has also been taking shelter, but in the Kharkiv metro.

“The woman behind me has a young child in a pram, can you imagine what it’s like being in these conditions? And the shooting doesn’t stop.”

Maryana says she can’t stop crying from shock.

“I have never been a religious person, but I am praying now and am asking everyone else to pray for Ukraine.”

Elena and her daughter were able to escape from Kharkiv soon after shelling started.

“We woke up and we were under attack. It was incredibly scary. We are asking to stop this war against the Ukrainian people”.
