In his nightly address on Monday, Ukraine's President Volodymyr Zelensky accused Moscow of forgetting the lessons of the Second World War after Russia's foreign minister claimed that Adolf Hitler "had Jewish blood".

Sergei Lavrov made the comments to try to justify Russia's portrayal of Ukraine as "Nazi," - despite the fact that its president is Jewish - provoking condemnation from Israel.

More than 200 civilians are still holed up in Mariupol's huge Azovstal steelworks, the city's mayor Vadym Boychenko has said, Reuters news agency reports.

A number of civilians were evacuated from the steelworks - the last hold-out of Ukrainian troops in the strategically significant city - on Sunday.

The UN and Red Cross have said they hope to evacuate more civilians today.

Boychenko said about 100,000 civilians were still in Mariupol, which has been under siege for weeks.

The UK's Ministry of Defence has released its daily intelligence update on the war in Ukraine, external.

The MoD says Russia's military is now "significantly weaker" as a result of invading Ukraine.

It says the recovery of Russia's military will be made more difficult by sanctions imposed on Moscow, and in the long term this will impede the country's ability to deploy a conventional military force.

It notes that Russia's defence budget roughly doubled between 2005 and 2018, with investment in several high-end air, land and sea capabilities.

But the modernisation of Russia's physical equipment has not enabled it to dominate the war in Ukraine, due to failures in strategic planning, the MoD adds.

Israel has reacted with fury after Russia's foreign minister claimed that Nazi leader Adolf Hitler "had Jewish blood".

Sergei Lavrov made the comments to try to justify Russia's portrayal of Ukraine as "Nazi" despite the fact that its president is Jewish.

Israel's foreign ministry summoned Russia's ambassador for "clarification" and demanded an apology.

The comments have been condemned across the political spectrum in Israel and by newspapers in the country.

In an analysis piece, the Jerusalem Post, external said it meant Israel could no longer be neutral on the war in Ukraine.

Jerusalem’s best-laid plans to "somehow stay above the war" have now been undone, it says.

Another Israeli newspaper, Haaretz, carries comments, external from the American Jewish Committee saying: "We’ve repeatedly said denazification is needed - in Moscow, not Kyiv.

"Russian Foreign Minister Lavrov, one of Putin’s enablers-in-chief, makes clear why. His statement is grotesque."

Russian troops have launched new attacks on the Azovstal steel works in Mariupol, after a group of about 100 civilians were evacuated.

Despite this, the UN and Red Cross hope to oversee more civilian evacuations early on Tuesday morning. Hundreds of non-combatants remain hold up underground at the sprawling factory site alongside Ukrainian fighters, forces there say.

"This includes dozens of children who are still in bunkers underneath the plant," National Guard commander Denys Shlega said on Monday.

Russian forces have been shelling the steel plant with "all kinds of weapons", he added.

A first group of evacuees from the plant were expected to arrive in the Ukrainian-controlled city of Zaporizhzhia on Monday - but the rescue efforts ran into delays.

The BBC's Laura Bicker, who is in Zaporizhzhia, reports that the buses carrying the evacuees had to make the 200km trip along a road which is now partly rubble.

Ukraine's south has seen heavy fighting as Russia seeks to take key port areas around the Black Sea.

Ukrainian troops are digging in around the city of Mykolaiv, while civilians there endure daily Russian attacks.

BBC video journalist Abdujalil Abdurasulov has been with the Ukrainian army in an area near Mykolaiv, just a few kilometres from Russian positions.

A senior US official has warned that Russia is preparing to hold votes on independence in occupied territory in eastern Ukraine – a move he described as a sham.

"According to the most recent reports, we believe that Russia will try to annex the Donetsk People's Republic and Luhansk People's Republic to Russia," said Michael Carpenter, the US ambassador to the Organization for Security and Co-operation in Europe.

"The reports state that Russia plans to engineer referenda upon joining sometime in mid-May."

"Pseudo referendums" are something President Zelensky has warned about in the past.

Earlier this year, Russian President Vladimir Putin announced he was recognising the independence of the two breakaway regions.

UK Prime Minister Boris Johnson is expected to describe Ukraine's resistance to the Russian invasion as the country's "finest hour" when he address its parliament virtually on Tuesday.

Johnson is set to say that the UK Parliament met throughout World War Two, just as Ukraine's Verkhovna Rada has done through the war with Russia, and that the British people showed "such unity and resolve that we remember our time of greatest peril as our finest hour".

"This is Ukraine's finest hour, an epic chapter in your national story that will be remembered and recounted for generations to come," he will say.

Johnson will also announce a £300m package in extra military support, which will include electronic warfare equipment, a counter-battery radar system, GPS jammers and night-vision devices.

See you again on Tuesday morning Kyiv time. We leave you with a roundup of the main developments from today.

• A rocket exploded in the Black Sea port city of Odesa on Monday evening
• Ukraine's president said a 14-year old boy was killed and a 17-year-old girl was injured in the strike
• More than 100 civilians evacuated from Mariupol's Azovstal steel plant have been arriving in the Ukrainian-controlled city of Zaporizhzhia around 200km away. The group left their dark refuge for the first time in 60 days after negotiations to safeguard their passage finally succeeded
• Hundreds of people, including dozens of small children, are still trapped in the massive plant, a Ukrainian fighter there says. And shortly after the evacuees got out Russian forces resumed their shelling, he said
• EU ministers meeting in Brussels are divided over whether or not to impose an embargo on Russian oil imports
• Germany has shifted from its more cautious approach, saying that it would be ready to support an oil embargo, but there's still no agreement. This morning Hungary made clear that it remains opposed to it
• Russia is planning to annex the Donetsk and Luhansk regions of eastern Ukraine after holding sham elections there planned for mid-May, according to a senior US diplomat

In his nightly address, Zelensky also slammed Russia's Foreign Minister Sergei Lavrov for remarks that have caused uproar in Israel.

Lavrov claimed on Sunday that Nazi leader Adolf Hitler "had Jewish blood". The foreign minister was at the time trying to justify Russia's portrayal of Ukraine as "Nazi" despite the fact its president, Zelensky, is Jewish.

Zelensky hit back on Monday: "Yesterday, for example, Russia's foreign minister openly and without hesitation said that the biggest anti-Semites were allegedly among the Jews themselves.

"And that Hitler allegedly had Jewish blood. How could this be said on the eve of the anniversary of the victory over Nazism? These words mean that Russia's top diplomat is blaming the Jewish people for Nazi crimes. No words.

"Of course, there is a big scandal in Israel today as regards these words. However, no one hears objections or excuses from Moscow. There is silence. Hence, they agree with what their foreign minister said."

A 14-year-old boy was killed during Monday's missile strike in Odesa by the Russian military, President Voloydmyr Zelensky says in his nightly speech.

A 17-year-old girl suffered a shrapnel wound in the same strike, he added.

"What is it? For what? What did these children and the dormitory threaten the Russian state with?" Zelensky asks.

He also spoke of the destruction by shelling of a gymnasium in the Luhansk region that had withstood two world wars.

"As we see, this gymnasium turned out to be a terrible threat to modern Russia," says Zelensky sarcastically.

He also adds that Denmark has become the 29th country to reopen its embassy in Kyiv, and that the EU will pass a new sanctions package against Russia "in the near future".

He says the latest EU sanctions will "include clear steps to block Russia's energy revenues. So that the terrorist state is not given a billion euros a day for fuel."

"We continue to do everything to save our people from Mariupol," he says, after about 100 civilians were allowed to flee the city on Sunday.

He also notes that an evacuation from Mariupol is planned for Tuesday with the evacuees expected to travel by humanitarian corridor to the Ukrainian cities of Berdyansk, Tokmak and Vasylivka.

Zelensky added that Ukraine's armed forces have repelled several Russian advances in the south and east of the country, but adds that "everywhere the situation remains extremely difficult".

Russia has rerouted internet traffic in the Ukrainian region of Kherson through Russian communications infrastructure, according to the internet service disruption monitor NetBlocks.

The London-based organisation said it had tracked a near-total internet blackout across Kherson on Saturday.

It said this affected various Ukrainian providers.

But after connection was restored, various metrics showed traffic was going through Russia.

"Connectivity on the network has been routed via Russia’s internet instead of Ukrainian telecoms infrastructure and is hence likely now subject to Russian internet regulations, surveillance, and censorship," NetBlocks said on its website.

Russia claims it has taken full control of Kherson region.

Foreign embassies are slowly reopening their doors in Ukraine's capital, as the security situation there improves.

Today Hungary became the latest country to announce that its embassy was operating out of Kyiv once again, the same day that Denmark said it too would be reopening its embassy. They follow France, which made the move two weeks ago.

The UK's ambassador Melinda Simmons came back to Kyiv this weekend, describing her return as "an extraordinary thing". The British embassy hasn't reopened its doors yet but the Foreign Office says it will do so soon.

The US is yet to return its diplomats to the capital, but today American officials in Lviv said the delegation would be back in Kyiv by the end of the month.

Russian troops may have withdrawn from their positions around the Ukrainian capital but the city is still vulnerable to attacks from the air.

Last week, Moscow announced it was primed to carry out strikes in the capital and warned the presence of foreign advisers in those sites "will not necessarily be a problem to Russia deciding to take retaliatory action".

There are fresh attempts to set up a humanitarian corridor from Mariupol

An evacuation of civilians with the support of the UN and Red Cross has been agreed for Tuesday at 07:00 local time (05:00 BST), Mariupol City Council said on Telegram.

The announcement comes as hundreds of people remain trapped in the Azovstal plant, despite some managing to leave on Sunday.

Officials tried to evacuate civilians in Mariupol several times over the past months.

But most attempts failed - with Russia breaking its promised temporary ceasefire window to allow civilians out of bombarded cities -by blocking and shelling escape routes.

Many Mariupol residents fled on foot or by car when efforts to organise mass evacuations by bus collapsed.

The city is almost fully under Russian control, with much of it destroyed in weeks of heavy Russian bombardment.

US First Lady Jill Biden is set to travel to Romania and Slovakia later this week to meet Ukrainian refugees.

She is due to spend Sunday - which is Mother's Day in the US - with mothers and children displaced by the conflict to Slovakia.

Her trip represents the latest show of support for Ukraine from high-level American representatives - following Sunday's unannounced visit to Kyiv from Nancy Pelosi, Speaker of the House of Representatives.

During Biden's journey to eastern Europe, from 5-9 May, she is also due to meet US service personnel and diplomats, as well as humanitarian workers and teachers.

Russia is planning imminently to "annex" two eastern regions of Ukraine battered by its invasion, according to the US ambassador to the Organization for Security and Co-operation in Europe.

Speaking to reporters in Washington, Michael Carpenter said: "According to the most recent reports, we believe that Russia will try to annex the Donetsk People's Republic and Lugansk People's Republic to Russia.

"The reports state that Russia plans to engineer referenda upon joining sometime in mid-May."

Earlier this year, Russian President Vladimir Putin announced he was recognising the independence of the two breakaway regions.

The self-proclaimed Donetsk People’s Republic and Luhansk People’s Republic are in the east of Ukraine and could allow Russia to move troops into the country.

A senior official at the US Department of Defence has just confirmed to reporters that a top Russian general visited the Donbas region of Ukraine last week.

Speaking on condition of anonymity, the US official said that General Valery Gerasimov was there, but that the US could not confirm that he had been injured, as some reports suggest.

It is "certainly possible" that he was there to conduct a "manner of oversight" the official added.

The official went on to describe Russia's offensive in Ukraine's east as "very tepid," "minimal at best", and "anaemic".

The official said Russian airstrikes continue in Mariupol, and that Russian troops are increasingly relying on unsophisticated "dumb bombs" that have to be dropped from lower altitudes that more advanced weapons.

The official also said the US has transferred more than 70 of the 90 howitzer artillery guns promised to Ukraine, as well as tens of thousands of shells. In the past 24 hours, 14 US military flights have sent supplies to the region, the official added.

However, none of the helicopters that President Biden approved for Ukraine have yet to be sent.

We've been reporting that a rocket strike hit the Black Sea port city of Odesa, in southern Ukraine, on Monday evening.

People died and some were wounded as a result, according to the head of the Odesa administration.

A residential building, which had five people in it at the time of the attack was damaged, and a 15-year-old boy died, Odessa city council said on Telegram. A second child was taken to hospital.

The blast damaged the building's windows and walls as well as the roof of the adjacent Orthodox Church, Ukrainian officials said.

We do not yet know how many people and buildings have been affected and which area of the city has been hit.

Ukrainian officials blamed Russia for the attack.

Odesa - Ukraine's largest and most lucrative sea port - has so far been largely spared fighting. But on Saturday, the runway at the airport was damaged in a Russian strike.

Odesa is seen as an important target, both strategic and symbolic.

Nataliia Roberts is trying to bring her best friend, Yuliia, and her three daughters to stay with her in Wales after hearing of the dire conditions they faced in Mariupol.

Yuliia and her three daughters, aged 11, six and three, used to run out of their basement shelter in the besieged city after it had rained to drink the rainwater, as they were so thirsty.

After their home was destroyed, the family had to find sanctuary in a communal basement which offered some shelter, but Yuliia barely had any food to feed the children.

"The kids were asking for food so much, that's why she tried to feed them at bed time, so they felt full before bed," said worried friend Nataliia, watching on from her home in north Wales.
