We've received official word that at least six people have died in Russian missile strikes on Lviv - including one child.

Reporting restrictions from the military authorities here mean we can't publish any photos yet of what we've seen.

En route to the site of one of the blasts we were stopped on the road by armed men. They said we could not continue.

Air raid sirens then sounded again. As things stand we're in a car supplies shop waiting for the all clear.

It's a shock for the city. Lviv is in the far west of Ukraine and has until now been relatively untouched by the violence - the last casualties from a strike were in March.

It comes days after Ukrainian air defences said they had downed four cruise missiles aimed at the region.

Yuri Sak - one of the advisers to Ukraine's defence minister, who is in western Ukraine - has been talking to the BBC about the strikes on the city of Lviv.

"What happened today is very disturbing and alarming because this is a very powerful missile strike [on] civilian infrastructure," he told BBC Radio 4's Today programme.

There is no official confirmation on casualties and damage, and there won't be so as to not give out information to Russia on what has been hit, he adds.

"What happened today proves one more time that, while the major build-up of Russian forces continues in the east of Ukraine, the whole of the country continues to be at risk," he says, adding that the country needs to be armed now.

Six people have been killed and eight wounded in Lviv after missiles struck military facilities and a car tyre service point in the western Ukrainian city this morning, regional governor Maksym Kozytsky has confirmed.

A child was among the dead, he said.

Ukrainian authorities in the southern region of Dnipropetrovsk also reported multiple explosions on Monday, and said some of the missiles hit areas close to a railway station and other rail facilities.

According to the West Air Command, four missile strikes struck Lviv, leaving facilities severely damaged, and fires that broke out a result of the hits are still being extinguished.

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

Unconfirmed photos of a stricken Russian warship - allegedly the sunken Moskva - are circulating on social media.

But what do we know about the ship's sinking?

The Moskva was an important part of Russia's naval strategy in Ukraine - a 510-crew warship which was the third largest in Moscow's active fleet, armed with an array of anti-ship and anti-submarine weapons, as well as heavy defences.

So when Ukraine said it had sunk the Moskva using its Neptune missiles, the news was seen as a big win and symbolically important.

But Russia has a different version of events. It claims that an ammunition explosion aboard caused a fire, and the ship sank while being towed back to port. Russia also says the entire crew was safely evacuated. It published a video on Saturday it said showed some of the crew safe and sound.

US officials back Ukraine's version of the story.

And on Sunday, a report from Novaya Gazeta Europe newspaper suggested that about 40 sailors may have been killed, several are missing and many others wounded.

In an interview with the mother of a sailor it said was aboard, the newspaper said her son had told her by phone that the ship was hit by three missiles from land.

"He called me and was crying because of what he had seen. It was terrifying," she said, adding that she herself was terrified of having to wait for him to finish his service.

• In depth: What do we know about the Moskva?

Justin Crump, military analyst and chief executive of the intelligence consultancy Sibylline, has been talking to the BBC about the strikes taking place right across Ukraine.

This has been the Russian strategy to some extent since the start of the conflict, he says; arguably they did not target infrastructure and military targets enough, and they missed those shock-and-awe moments - they're now catching up with that and accelerating the tempo, he tells BBC Radio 4's Today programme.

A lot of that has been linked to stopping supplies getting to the Donbas, where they're planning their largest operation, he says. They're targeting railway junctions, military supplies where they can, fuel supplies, a suspected training camp location for territorial volunteers - plus infrastructure strikes in Mariupol.

On the question of Ukrainian ammunition running out, he says several elements are at play: the rate at which ammunitions are used in modern combat are "prodigiously high", including small-arms ammunition and particularly artillery ammunition; the calibres are different - they are different sorts of rounds; and as supply comes from Western nations with more modern weapons, that complicates the supply problem.

There was an air raid alert warning here this morning at about 07:45 local time (05:45 GMT). There have been a number of those alerts over the past few days in the early hours of the morning, and we thought that would be another one that may pass without incident.

In previous air raid alerts, there was a Russian attack, but Ukrainian officials said they managed to shoot down the missiles before they did any damage.

It's a marked escalation for people here in Lviv. There was an attack on the edge of the city earlier in the conflict, on an old oil depot, and there have been a number of air raid alerts but no successful attacks and no damage done - until this morning.

We're not clear exactly what's been hit. Some of that smoke apparently is coming from close to the city's railway station, but there is no confirmation of what the target was.

Russian armed forces are completing the formation of an aggressive group in the Eastern Operation Zone, Ukraine's armed forces have said in their daily update. Here's what else they said:

• Russian troops have continued a partial blockade of Kharkiv
• In Donetsk, shelling has continued in the Siversk and Pokrovsk settlements
• Russia attempts to storm Novotoshkivsk, Popasna in Luhansk and Avdiyivka and Maryinka in Donetsk were unsuccessful
• Russian troops are still trying to enter the administrative borders of Kherson

The BBC could not independently verify this information.

The situation has changed here completely in the last hour or so.

People here had thought they were relatively safe; there had been one missile attack reported on the edge of the city since the start of the invasion.

It’s not clear what the targets are.

It is a real reminder to people of the risk that they face here, even though we are hundreds of miles away from the front-line fighting in the east of the country in the Donbas where the conflict had been expected to intensify.

But we have seen those renewed Russian attacks on a number of Ukrainian cities, including the capital, Kyiv, and this morning at least Lviv has come under attack.

Good morning and welcome to our UK audience if you're just joining our coverage. Here's a quick update on the latest developments in Ukraine:

• Five missile strikes have been reported in the western city of Lviv on Monday morning while air raid sirens were heard in Kyiv and several other parts of Ukraine

• Ukrainian President Volodymyr Zelensky says he has invited French President Emmanuel Macron to visit the country to see for himself the acts of "genocide" committed by Russian forces
• Russian troops are issuing "movement passes" to those who remain in the besieged city of Mariupol, an adviser to the city's mayor has said residents will not be able to move between districts or be out on the streets without these passes
• Ukrainian authorities have asked residents of the Luhansk region in the east to evacuate immediately, saying this may be their "last chance" to leave safely

With that, it's Yvette Tan and Meryl Sebastian in Asia signing out and handing over to Jeremy Gahagan and Alexandra Fouché in London.

Four missiles have struck the Lviv region, according to the governor Makysm Kozytskyi.

On a post on his official Telegram channel he said this was according to "preliminary information".

"Stay in the shelters", he wrote.

Reporting from Lviv

We’ve witnessed at least five explosions in western Lviv, a city near Ukraine’s border with Poland.

As yet, we don’t have official word on what’s happened. But thick black and grey smoke is rising from the site of the blasts, and one of the BBC team saw a missile in flight.

An air raid alarm sounded about 45 minutes before the blast. Such sirens are common in Lviv though - many people were still on the streets, and we were in the hotel restaurant on the top floor when we saw the plumes of smoke in the distance.

Last week, the city reported several Russian cruise missiles destroyed by anti-aircraft fire.

We’ll bring you more information as we get it.

The southern port city of Mykolaiv was one of the first places Russian forces attacked in February.

Intense shelling in the city has forced many residents to flee, but some of the city’s elderly population has been left to fend for themselves.

The BBC’s Catherine Byaruhanga went to the neighbourhood of Kulbakino, to meet those left behind.

Ukrainian President Volodymyr Zelensky said in an interview with CNN, external that he has invited French President Emmanuel Macron to visit Ukraine to see for himself that Russian forces had committed “genocide.”Macron has been reluctant to use the word genocide, stating earlier that he was "not sure that an escalation of rhetoric serves that cause".

"I invited him to come when he will have the opportunity. He'll come and see, and I am sure he will understand," said Zelensky.

Zelensky has previously said that Macron’s reluctance to use the term was “very painful for us.”

The United States, which has historically been reluctant to accuse states of genocide, last week accused Russian President Vladimir Putin of committing acts of genocide by trying to "wipe out the idea" of a Ukrainian identity.

The UN Genocide Convention, of which the US is a signatory, requires countries to intervene once genocide is formally identified.

An adviser to the mayor of Mariupol says that Russian troops are issuing "movement passes" to those who remain in the city.

Petro Andriushchenko - who is not currently in the city but shares information on the ground - made the allegation via Telegram on Sunday, sharing a photo that appears to show people lining up.

"Hundreds of citizens have to stand in line to get a pass, without which next week it will be impossible not only to move between districts of the city, but also to be on the streets," he wrote.

Andriushchenko suggested that occupying forces were probably gathering information on, or filtering through, those who remain in the city.

The BBC has not been able to independently verify the official's claims.

Russia claims to have control of most of the city, with Ukrainian defenders reportedly contained to a sprawling industrial area called the Azovstal steelworks. Russian officials offered to spare the lives of those troops if they surrendered on Sunday - an offer which was ignored.

Ukraine's prime minister says the soldiers there will "fight till the end".

Residents of the Luhansk region in eastern Ukraine have been urged to evacuate immediately, according to a report by Ukrainian news agency UNIAN.

"Next week may be difficult. [This] may be the last time we still have a chance to save you," the head of the Luhansk regional administration Sergei Gaidai was quoted as saying.

Russian forces have trained their focused on capturing Luhansk and Donetsk which are part of the Donbas region of eastern Ukraine, an old coal and steel-producing area.

Putin had recognised the entirety of the two eastern regions as independent of Ukraine just before the war.

Ukraine's armed forces have been preparing themselves for a brutal Russian offensive in this region.

If you're just joining us now, good morning. Here's a quick look at the latest developments in Ukraine:

• Ukraine’s foreign minister Dmytro Kuleba said Russian troops in the Ukrainian port city of Mariupol had “decided to raze the city to the ground at any cost”. Hours earlier the country's Prime Minister Denys Shymhal said Mariupol "has not fallen" despite Russia's ultimatum for its surrender and remaining Ukrainian forces there will "fight to the end"

• More people returned to Ukraine from Poland than those who have left, for the first time since the war began. Nearly 22,000 people crossed into Ukraine on Saturday, as 19,200 left, figures from the Polish border service showed

• Another Russian general has been killed in combat - deputy commander of the 8th Army Maj Gen Vladimir Frolov. In late March, Western officials said Russia had lost seven generals in the war so far. Russia has not confirmed that figure

I’ve been hearing the accounts of badly wounded civilians from war in the Donbas region as they are evacuated by train to the west of Ukraine.

Twelve-year-old Katia is carried on board on a stretcher. Her mum was killed in last week’s missile attack on Kramatorsk station, which left Katia badly injured and needing further hospital treatment. She tells me the scene of the blast was “like a nightmare”. She grieves for her mother and leaves without her father, who is staying behind in the east.

Another family waiting nearby has also had a devastating loss. Tanya explains that her eldest daughter Marina was killed a few days ago. It happened in a car crash during the rush to evacuate as the outskirts of her town were under heavy bombardment.

She says she was trying to get her family to a safe place. One of her younger children has a fractured skull.

“I’m scared for my children,” says Tanya. “I’m very sorry for the price I had to pay for leaving my own home. We didn’t want to go.”

Platform one is filled with stretchers as patients are carried on board. Staff from the medical charity MSF who have organised the evacuation load people onto specially modified trains. The evacuation involves a gruelling 20-hour journey west to Lviv along lines which have already faced attack.

In Soviet-era carriages they flee Russia’s advance, helping free up hospital space in the east where fears grow of a major assault.

After a number of defeats near Ukraine's capital Kyiv, Russia has shifted most of its focus to the east, into the disputed Donbas region.

Ukrainian and Russian forces are now preparing for what might be a decisive battle there.

But for now for residents of Sievierodonetsk - a government-held city nestled within Donbas - this change in strategy means coping with daily life amid the ruins left by the war. These photographs, taken on Saturday, show the extent of some of the damage.

Ukraine’s foreign minister says the city of Mariupol “doesn’t exist anymore”.

The south-eastern port city has been devastated by continuous Russian attacks since the war began nearly two months ago.

Dmytro Kuleba told CBS’s Face the Nation on Sunday that the invading troops have “decided to raze the city to the ground at any cost”.

An unverified photo claiming to show the Russian warship Moskva stricken at sea has been posted online.

The source of the image is unclear, and the BBC has not verified its authenticity.

Military watchers say the photograph may be genuine. Rob Lee, a PhD student at the Department of War Studies at King's College London, tweeted that it "looks like a legit photo".

And OSINTtechnical, a well-known Twitter account sharing open-source intelligence information, wrote: "I can’t verify the authenticity, but this is a Slava class cruiser and I don’t think any of them have been destroyed in this manner."

The fate of the ship has been hotly contested by Ukraine - which says it sank it with a missile strike - and Russia, which says it sank after a fire on board.
