Early on, Olena Kurilo became the face of Russia's invasion of Ukraine.

Bloodied and bandaged, the 53-year-old teacher's picture was on the front pages of newspapers across the world.

Over the next few days, Russia's government social media accounts began to post a video claiming that Olena hadn't been injured at all.

This claim is baseless and wild conspiracy theories like these are not uncommon on social media.

But what makes this conspiracy theory so odd is that it was shared by an official Russian government Twitter account - the Russian Mission in Geneva. Two weeks on, the tweet is still live.

It's part of a huge network of official Russian accounts that are spreading misinformation on Twitter and elsewhere.

A member of the Russian military was killed in the Ukranian town of Chernobayevka after an artillery strike, said Ukraine's General Staff of the Armed Forces in a Facebook post on Saturday.

In the post, it said Lieutenant General Andrei Mordvichev, commander of the 8th Combined Arms Army of the Southern Military District of the Russian Armed Forces had died.

In its daily update, it also added that the war frontline had not changed significantly in the past 24 hours, but said Ukraine's troops had managed to destroy several columns with Russian military personnel in the Mykolaiv and Sumy regions.

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

Empty prams have been lined up at a central square in Lviv, outside the city council, in tribute to the children who have died in the war.

Ukraine authorities say at least 109 have been killed so far.

Each pram is said to represent one child.

Former US Presidents Bill Clinton and George W Bush have visited a Ukrainian church in Chicago in a show of support for the Ukrainian people.

They laid sunflowers wrapped with blue and yellow ribbons at the Saints Volodymyr and Olha Catholic Church.

President Bush wrote in a separate post on Twitter saying:"America stands in solidarity with the people of Ukraine as they fight for their freedom and their future."

Former British PM Gordon Brown says Vladimir Putin should face an international tribunal over his actions in Ukraine.

The ex-Labour leader is among 140 academics, lawyers and politicians to sign a petition calling for a legal system modelled on the Nuremberg trials of Nazi war criminals after World War Two.

The International Criminal Court is already investigating the Russian leader for alleged war crimes, but some say the ICC's powers are limited.

Writing in the Daily Mail, Brown said creating a tribunal would close off a loophole in international law "that Putin could use to dodge justice".

Ukraine's Armed Forces said that its air defences had destroyed at least 12 Russian air targets - two planes, three helicopters, three drones and four cruise missiles.

Local reports citing an adviser to the head of the President's office added that armed forces had also hit the Chornobaivka airfield, where Russia had placed part of its fleet - for the sixth time.

The BBC could not independently verify this information.

Ukrainian President Volodymyr Zelensky has on Saturday called for meaningful peace and security talks "without delay" with Moscow.

He said it was Russia's only chance to limit the damage from its "mistakes" in the wake of its invasion.

"This is the only chance for Russia to reduce the damage from its own mistakes," Zelensky said in his nightly video address.

"It's time to meet, it's time to talk, it's time to restore territorial integrity and justice for Ukraine.

"Otherwise, Russia's losses will be such that you will need several generations to recover."

If you're just joining us, here's a summary of the latest developments:

• Ukrainian President Volodymyr Zelensky has called on peace talks "without delay" with Moscow
• He added that it was time to talk, saying "otherwise, Russia's losses will be such that [it] will need several generations to recover"
• In the embattled town of Mariupol, its mayor confirmed Russian reports that fighting had reached the centre of the city. More than 80% of the city's residential buildings are said to be either damaged or destroyed since Russia bombardment began

• Hundreds are still trapped in the basement of the theatre in Mariupol which was bombed by Russia on Thursday
• Ukraine President Zelensky said Russian shelling has prevented city authorities from establishing effective humanitarian corridors to the besieged city
• In Moscow, thousands attended a rally addressed by President Putin to celebrate eight years since the annexation of Crimea. "We'll definitely carry out all the plans we have made," Putin told the crowd. His address, however, cut off abruptly on state TV in what Kremlin called a technical glitch

It is a rare thing to live through a moment of huge historical consequence and understand in real time that is what it is.

In November 1989, when the Berlin Wall came down and a divided Europe was made whole again, I was in Prague, the capital of what was then Czechoslovakia.

There, the Communist regime collapsed and within weeks a dissident playwright became the president of a new democratic state. It was an exhilarating moment, dizzying in its pace.

I sensed, even at the time, that I had watched the world pivot - that it was one of those rare moments when you know the world is remaking itself before your eyes.

Vladimir's Putin's invasion of Ukraine has changed the world too and 2022 is now one of those pivotal times.

We are living in new and more dangerous times.

There have been enormous spikes in global food and energy prices since Russia invaded Ukraine on 24 February.

A US think tank - the Center for Global Development - is now warning, external that the scale of these spikes could push more than 40 million people around the world into "extreme poverty".

It points in particular to how important the ex-Soviet region is to agricultural trade. Russia and Ukraine account for 29% of the world's wheat. Russia and Belarus account for one-sixth of the world's fertiliser.

The impact of these shocks will be felt widely, the think tank says, but it will hit poorer countries disproportionately.

CGD's experts recommend that grain producers - including in the G20 - must keep their markets open and sanction-free, while governments and international agencies must "act quickly and generously" to support humanitarian needs.

No peace on Earth, but Russia and the US are working together just fine in the close confines of the International Space Station.

Three Russian cosmonauts - commander Oleg Artemyev, Denis Matveev and Sergey Korsakov - docked safely on Friday for a six-and-a-half-month mission.

The ISS is a 23-year collaboration between the US, Russia and other countries.

The trio was warmly welcomed aboard by a crew that comprises four Americans, two other Russians and one German.

It comes just days after news that US astronaut Mark Vande Hei - who logged a Nasa record-breaking 355 days in orbit - is set to leave the ISS aboard a Russian capsule landing in Kazakhstan.

Friday's daily intelligence assessment , externalby the Institute for the Study of War - a US think tank - offers some interesting insights into how Russia is trying to stamp its authority on territory it has captured in Ukraine.

The analysis draws largely on reports from the General Staff of the Ukrainian Armed Forces.

According to ISW, the invading forces may be attempting to establish "a strict administrative and police regime" in several areas, while also distributing food to civilians in order to maintain a positive image.

It adds that Russia continues to detain pro-Ukrainian civil servants, activists and others.

Those repressive measures come as Russia has "significantly exhausted its human resources" and is taking "extreme measures in matters of staffing", even allegedly dismissing a general for his performance.

Meanwhile, the think tank finds that Ukrainian forces have launched a successful counterattack near the encircled southern city of Mykolaiv, and halted the Russian advance into Kharkiv.

Europe's leading car-parts maker Bosch is halting production at its Russian factories.

Blaming supply chain issues and disrupted deliveries, the German giant admitted it may have to end its operations in the country for good.

But the pullout comes amid claims by Ukraine that it discovered "one of the main components that power" Russian infantry vehicles is supplied by Bosch.

Foreign Minister Dmytro Kuleba told German media that Bosch has been supplying these components to the Russian military "for years".

An investigation is now said to be underway in Germany to find out whether the use of Bosch parts by the Russian military violates sanctions imposed on Moscow by the European Union.

The company says it had launched its own inquiry into the matter and is taking the allegations "very seriously".

Separately on Friday, US oil field services giant Halliburton suspended all future business with Russia.

A senior EU official has told the BBC they “wouldn’t bet money” on Boris Johnson being invited to next week’s European Council.

The UK Prime Minister is expected to be in Brussels at that time, on Thursday, for the extraordinary Nato meeting.

US President Joe Bidenisdue to attend the EU leaders’ summit – “We have to make sure that goes well,” says the official.

On Johnson’s attendance, the official said they wouldn’t “exclude anything”, but there would have to be a “really good reason” to invite him.

It was also stressed any lack of invitation shouldn’t be regarded as a particular snub, given various leaders will be in town for Nato but won’t necessarily attend the council.

EU sources say European Council president Charles Michel and Johnson are scheduled to speak on Monday afternoon.

But on Friday Downing Street said it didn’t believe a call had been confirmed – and any invitation to the EU summit was a “matter for the council”.

British Foreign Secretary Liz Truss recently attended a meeting of the EU’s Foreign Affairs Council.

Residents of besieged Mariupol remain on the brink as Russian forces continue to push into the southern port city.

The mayor confirmed to the BBC earlier that gun battles had reached the centre of the city.

Up to 400,000 people have been trapped in Mariupol for over two weeks, though Ukrainian officials say nearly 5,000 managed to escape on Friday.

The city has been under a bombardment that has cut electricity, heating and water supply.

Ukrainian officials said late on Friday that Mariupol had lost its access to the Sea of Azov.

Rescuers are still digging through the rubble of the city's theatre, which was bombed on Wednesday.

According to President Volodymyr Zelensky, its basement may have been sheltering as many as 1,300 people at the time.

More than 80% of the city's residential buildings are said to be either damaged or destroyed.
