Ukraine's deputy prime minister Iryna Vereshchuk has called Russia's six proposed humanitarian corridors "unacceptable".

Of the four cities mentioned in Russia's proposal, only Mariupol and Sumy have evacuation routes that lead to other parts of Ukraine. All other routes lead directly to Russia or Belarus, a key Russian ally in the war.

"This is an unacceptable way of opening humanitarian corridors," said Vereshchuk.

"Our people will not go from Kyiv to Belarus to then be flown to the Russian Federation."

Overnight on Sunday, Russia sent a letter proposing a temporary ceasefire window from 10:00 Russian time (07:00 GMT). In response, Ukraine sent Russia its conditions on the routes, specifically the opening of corridors for the evacuation of people to the west of Ukraine - away from Russia.

Vereshchuk called on the US, UK and France for assistance in establishing the corridors.

Ukrainian citizens should be allowed to leave their homes through Ukrainian territory, a spokesman for Ukrainian President Volodymyr Zelensky said.

The boss of one of the world's biggest fertiliser companies has said the war in Ukraine will deliver a shock to the global supply and cost of food.

Svein Tore Holsether, the boss of Yara International, said fertiliser prices, which were already high before the Russian invasion due to skyrocketing gas prices, could continue to soar.

Yara, which operates in more than 60 countries, buys considerable amounts of essential raw materials from Russia.

"We were already in a difficult situation before the war," Holsether told the BBC. "Now it's additional disruption to the supply chains and we're getting close to the most important part of this season for the Northern hemisphere, where a lot of fertiliser needs to move on and that will quite likely be impacted."

Russia produces enormous amounts of nutrients, like potash and phosphate - key ingredients in fertilisers, which enable plants and crops to grow.

"For me, it's not whether we are moving into a global food crisis - it's how large the crisis will be," Holsether added.

From his underground shelter in a secret location in Kyiv, Ukraine's youngest cabinet minister is waging a digital war on Russia.

Using his preferred weapon - social media - Mykhailo Fedorov has been urging chief executives of big businesses to cut ties with Moscow. He's also taken the unprecedented move of setting up a volunteer "IT Army of Ukraine" to launch cyber-attacks against "the enemy".

He has piled pressure on multinational companies to boycott Russia.

Apple, Google, Meta, Twitter, YouTube, Microsoft, Sony, Oracle... no tech giant has missed out on an official government letter.

Fedorov then posts his letters on social media so the world can see, plus some of the replies.

But some of his tactics are proving divisive.

As we've been reporting, Russia has proposed a new ceasefire to allow civilians to escape Ukraine.

Over the weekend, groups of civilians fleeing Irpin braved attacks and tried to flee, with at least one mortar attack killing a woman and two children.

The BBC's Jeremy Bowen spent the day in the town, which has found itself on the front line between Russian and Ukrainian forces over the past week.

We reported earlier that some of the new ceasefire corridors announced by Russia lead to Russia or Belarus.

Of the four cities mentioned, only the smaller ones - Mariupol and Sumy - have evacuation routes that lead to other parts of Ukraine.

The full list of routes was published by the Russian news agency Ria, citing a recently established body called the Interdepartmental Coordinating HQ for the Humanitarian Response in Ukraine.

The details are as follows:

Mariupol

• Route 1 - Novoazovsk, Taganrog, Rostov-on Don (Russia), then by air, road or rail to a chosen destination or temporary holding place
• Route 2 - Portivske, Mangush, Respublika, Rosivka, Bilmak, Polohi, Orekhiv, Zaporizhzhya (Ukraine)

Kharkiv

• Nekhoteyevka, Belgorod (Russia) then by air, road or rail

Sumy

• Route 1 - Sudzha, Belgorod then by any transport
• Route 2 - Sumy, Golubivka, Romny, Lokhvitsya, Lubny, Poltava (Ukraine)

Kyiv

• Hostomel, Rakivka, Sosnovka, Ivankiv, Orane, Chernobyl, Gden', Gomel (Belarus), then by air to Russia

The statement adds that Russian military will carry out "uninterrupted objective control of the evacuation, including with the use of drones".

A spokesperson for Ukrainian President Volodymyr Zelenskiy has called the proposal "completely immoral", saying Russia was trying to "use people's suffering to create a television picture".

UK government minister James Cleverly has called Russian plans for a temporary ceasefire - to allow civilians access to humanitarian corridors which lead to either Belarus or Russia - "cynical beyond belief".

"Providing evacuation into the arms of the country that is currently destroying yours is a nonsense," the minister for Europe and North America told BBC Breakfast.

He once again ruled out the prospect of Nato imposing a no-fly zone over Ukraine, saying President Putin was trying to drag Nato into conflict "to justify his false narrative that he is justifying in Russia against Nato aggression".

He said the UK would continue to help the Ukrainians defend themselves, and provide both economic and humanitarian support.

Asked about provision for refugees, he said there was no change to previous plans announced by the home secretary, stressing that there needed to be a process in place.

He said there was no target or limit to the numbers arriving - but it would "inevitably" grow beyond the 50 visas currently being reported - and work was ongoing to make the speed up the application process.

"We don't know exactly what the numbers will be - this is the largest refugee crisis since the second world war."

"We are looking to create something large-scale very quickly."

Dominik Stillhart, director of operations for the International Committee of the Red Cross (ICRC), has been speaking with BBC Radio 4's Today programme.

Asked what's gone wrong with so-called humanitarian corridors, he said they had been talking to both sides "for days", but problems remained confirming the detail of any ceasefire agreement - to allow civilians out of bombarded cities.

Stillhart said the challenge was to get the two parties to an agreement that is "concrete, actionable and precise".

He added that so far there had only been agrements "in principle", which had immediately broken down because they lacked precision, regarding routes and who can use them.

Illustrating his point, he said some ICRC staff had tried to get out of Mariupol along an agreed route on Sunday, but soon realised "the road indicated to them was actually mined".

"That is why it is so important that the two parties have a precise agreement for us then to be able to facilitate it on the ground."

Ukraine has said Russia's proposal on humanitarian corridors taking refugees to Belarus or Russia was "completely immoral".

Ukrainian citizens should be allowed to leave their homes through Ukrainian territory, a spokesman for Ukrainian President Volodymyr Zelensky said.

"This is a completely immoral story. People's suffering is used to create the desired television picture," the spokesman said in a written message quoted by Reuters news agency.

China's Red Cross will provide humanitarian aid to Ukraine, Foreign Minister Wang Yi has said, as he reiterated a call for diplomatic talks to continue.

He stressed China's friendship with Russia are "rock solid" and the prospects for cooperation are very broad.

Yi's words comes hours after Australia's Prime Minister Scott Morrison urged China to denounce Russia.

In a lengthy foreign policy speech in Sydney, Morrison said China had repeatedly spoken about respect for sovereignty and territorial integrity.

"It is up to China, at this hinge point of history, to demonstrate these are more than just words,” said Morrison, adding "no country would have a greater impact on Russia than China".

Until now, China's government has neither condemned nor condoned Russia's war on Ukraine and has even refrained from calling it an "invasion" in the first place.

But earlier this week, Wang signalled that China was ready to play a role in mediating a ceasefire.

More now on the reports of evacuation routes heading to Russia and Belarus. French President Emmanuel Macron denies requesting for those corridors to lead into Russia, French news outlet BFMTV reports.

"The president of the Republic has neither requested nor obtained corridors to Russia after his conversation with Vladimir Putin," the Elysee presidential palace told BFMTV, external.

"The president of the Republic insistently asks to let the civilian populations leave and to allow the transport of aid.

"It's another way for Putin to push his narrative and say that it is the Ukrainians who are the aggressors and they are the ones who offer asylum to everyone."

As we've been reporting, Russia has said it will open new humanitarian corridors to allow civilians to evacuate.

Evacuation routes published by Russia’s RIA Novosti news agency show civilians will be able to leave to Russia and Belarus.

The corridor from Kyiv will lead to Russian ally Belarus, and civilians from Kharkiv will only have a corridor leading to Russia.

Corridors from the cities of Mariupol and Sumy will lead both to other Ukrainian cities and to Russia, the AFP news agency reports.

If you're just joining us, this is what's been happening over the last few hours:

• Russia says it is opening new humanitarian corridors across multiple Ukrainian cities, including the capital Kyiv, on Monday to allow civilians to evacuate - it comes days after similar attempts at Mariupol failed after continued shelling from Russian forces during the agreed ceasefire hours, according to Ukraine

• Ukraine's president Volodymyr Zelensky has accused Russia of murdering civilians, after a Russian attack on Sunday in Irpin killed a young family

• Ukrainian defence officials claim their forces have re-taken the eastern city of Chuhuiv
• There has been renewed Russian shelling on the southern port city of Mykolaiv

• The UK has said it will give an extra $100m (£74m) to Ukraine to help keep the government running amid the Russian invasion
• Oil prices have soared to the highest level since 2008 after the US said it was discussing a potential embargo on Russian supplies with its allies

The hacking collective Anonymous claims to have hacked Russian state TV broadcasts to show footage of the war in Ukraine.

In a Twitter post, Anonymous said it hacked into channels including Russia 24, Channel One and Moscow 24, in addition to Russian streaming services Wink and Ivi.

The BBC has not been able to independently verify these claims.

In a separate post, the group said that it is involved "in the biggest Anonymous op ever seen", adding that it is concerned that some governments may see it as a threat and conduct false-flag operations to discredit it.

"Remember us when various powers turn their attention towards us, because it will happen," Anonymous said. "We can change the world for the better. That has always been the idea".

Australia's prime minister spoke earlier on Russia and Ukraine, but used the conflict as a clear warning to other countries about the threat he thinks is posed by China.

Russia’s invasion was a wake-up call to Europe but just “the latest example of an authoritarian regime seeking to challenge the status quo through threats and violence”, he said.

Scott Morrison didn’t directly mention China but said his government had been warning about the increasing aggression of autocratic regimes for years.

He even used the same language to describe Russia that he often saves for China – terms like “bullying, coercion and intimidation”.

He pressed home the point that Western democracies needed to be clear-eyed and united in their approach.

“Events are now lifting the veil. Perhaps the scales are beginning to fall from the world’s eyes also. At least I hope so,” Mr Morrison said.

Since 2017, Australia has increasingly voiced concern over China’s influence in the Indo-Pacific region.

It has often been the first to take steps countering this: enacting foreign interference laws in 2018, veto-ing local Chinese investment and business deals, and forming the Aukus security pact with the US and UK last year.

The US government is reportedly considering a trip by President Joe Biden to Saudi Arabia to ask the kingdom to bolster oil production.

Axios, a US political news outlet, is reporting that the trip would take place in the spring, as the White House scrambles to address a global energy crisis caused by Russia's invasion of Ukraine.

A White House spokesperson, however, said no such trip is yet being announced, and “a lot of this is premature speculation".

US and Venezuelan officials have also reportedly discussed easing oil sanctions. A number of US lawmakers have suggested Venezuelan oil could help replace Russian oil, according to the New York Times.

The US currently relies on Russia for 10% of its imports of crude oil and petroleum products.

On Sunday, House Speaker Nancy Pelosi said in a statement that US lawmakers were "exploring strong legislation" to isolate Russia, including a total ban on Russian oil and energy products to the US.

Biden last year scrapped Keystone XL, a Canada-to-US oil pipeline, citing climate change.

Russia will open new humanitarian corridors across multiple Ukrainian cities on Monday to allow civilians to evacuate, state media is reporting.

The ceasefire will take place from 10:00 Moscow time (07:00 GMT) according to Russia's defence ministry, with evacuation routes set up in the capital Kyiv, as well as Kharkiv, Mariupol and Sumy. All of these cities are currently under a significant Russian assault operation.

Ukrainian officials have yet to confirm this.

Over the weekend, two efforts to open a route to allow civilians to evacuate from Mariupol in the country's south-east collapsed.

Ukraine officials said this was because Russia continued to shell the city during the agreed ceasefire hours.

We have more information now on the renewed Russian shelling of the southern port city of Mykolaiv.

The city's mayor has confirmed earlier reports that Moscow's forces bombarded the city with artillery fire on Monday morning.

In a message posted to Facebook, Oleksandr Senkevych wrote that Russian troops had targeted residential buildings in the city, and shared a video of a block of flats engulfed in flames.

"There are many shells in the city that did not explode... do not approach, do not lift, and do not try to move them yourself," Senkevych warned.

The renewed assault comes a day after Ukrainian forces repelled a Russian attack on the city of 476,100 people and recaptured the local airport.

Ukrainian defence officials claim that their forces have re-taken the eastern city of Chuhuiv.

In an operational update posted to Facebook on Sunday night, Ukraine's General Staff said that Kyiv's forces had seized the city from Russian troops and had inflicted heavy losses on Moscow's forces during the battle.

Ukrainian officials also claimed that two high-ranking Russian commanders were killed during the battle for the city, which boasts a population of around 31,000 people.

The BBC cannot independently verify these claims.

Chuhuiv sits in a strategic location around 23 miles from Ukraine's second largest cityKharkiv, which has been under heavy shelling from Russian forces for over a week.

South Korea has said it will cut transactions with Russia's central bank.

The announcement by the country's foreign ministry marks Seoul's latest move to join Western nations' efforts to impose tough measures against Moscow over its invasion of Ukraine.

The US had earlier banned transactions with Russia's central bank, finance ministry, and sovereign wealth funds.

The European Union has also announced similar measures.

Australia’s Prime Minister has just delivered a lengthy foreign policy speech in Sydney where he pointedly singled out China and its response so far to Russia’s invasion.

“The world has heard China’s words about its commitment to global peace and respect for sovereignty and territorial integrity for a long time now.

It is up to China, at this hinge point of history, to demonstrate these are more than just words,” Scott Morrison said.

The early signs were "not good”, he said, pointing out Xi and Putin’s meeting at the Winter Olympics, China’s support for Russian wheat exports, and Beijing’s language which “pretended to… even a ‘legitimate’ cause for Russia to invade Ukraine.”

“No country would have a greater impact on Russia than China joining the rest of the world in denouncing Russia’s aggression and applying the same sanctions. So far they have not.”

Relations between China and Australia have dived in recent years as Canberra has vocalised concerns about Beijing’s alleged interference in domestic politics and affairs – something China denies.

The Morrison government has become more explicit in stating concerns about China’s power in the Indo-Pacific region. In the first half of his speech, Mr Morrison warned a “new arc of autocracy is instinctively aligning to challenge and reset the world order in their own image”.

He emphasised that Australia was working with other like-minded countries to punish Russia, noting: “This is important because we know that there are powerful actors in our region who are watching closely, looking for signs of weakness and division within the West.”

He thanked allies Japan, South Korea and Singapore for their sanctions on Russia – calling it a “welcome testimony to international solidarity in our region”.

China's response to this crisis has been closely scrutinised.

Earlier, the BBC's Robin Brant in Shanghai asked if it could be doing more to stop Russia's war in Ukraine.
