Invasion is war against children - Ukraine

The Ukrainian government has accused Moscow of targeting educational establishments, including schools and colleges, completely destroying more than 20 sites since the Russian invasion began.
Presidential advisor Daria Herasymchuk described the invasion as "a war against children".
Officials tweeted on Sunday
that the Russian invasion has so far killed 225 children and injured 413 - although these figures are likely to be higher, as they do not include casualties in occupied areas or where hostilities are currently ongoing.
Ms Herasymchuk said children were suffering the most in the eastern Donbas region, where the government has called for international help to repatriate children from orphanages in Russian-occupied territory.

Fighting rages across Ukraine
The bombing of a school where villagers had taken shelter is tragically just one attack among many this weekend as the war in Ukraine shows no sign of relenting.
There has been fierce fighting around Popasna in Luhansk in recent days amid a sustained Russian assault. Local governor Serhiy Haidai said Ukrainian forces had been pulling back and that everything in the town had been destroyed.
Chechen leader Ramzan Kadyrov, a key ally of Russian President Vladimir Putin, said his troops had taken control of most of the town.
Meanwhile, Russian-backed separatists in the neighbouring Donetsk region said the city of the same name and another town, Holmivskyi, had come under Ukrainian shelling on Sunday.
Both sides earlier talked of inflicting heavy losses on the other. The Ukrainian government reported killing 400 enemy soldiers, knocking out eight tanks and 28 other armoured vehicles, destroying a ship and a helicopter, and downing 27 drones.
Russia's military says its air force alone killed around 420 Ukrainian soldiers, putting 55 pieces of military hardware out of action. It also reports destroying a warship with a missile near the port of Odesa, and shooting down two attack planes and a helicopter.
The BBC has not independently confirmed these claims.

Azovstal fighters to give rare news conference
The fighters holed up inside the Azovstal steel plant in Mariupol are expected to hold a rare online news conference shortly, in what will likely include a plea for a plan to guarantee their rescue.
Ukrainian officials say all women, children and elderly who were sheltering in the site's underground bunkers and shelters have now been evacuated.
But with the civilians out, there are fears Russia may step up its attacks on the site. Russia says the fighters, believed to number in the hundreds, must lay down their arms. They reject this, saying they won't surrender.
We'll bring you updates from the news conference as it happens.
Those expected to speak to journalists include the Commander of the Azov Regiment, Lt Col Denis Radis Prokopenko and his deputy, Cpt Svyatoslav "Kalina" Palamar.

Permits needed to leave Mariupol, says mayor
Laura Bicker
BBC News
The mayor of Mariupol says Russian President Vladimir Putin is determing who lives, who leaves and who dies in the city.
Vadym Boichenko told the BBC that the 100,000 people still living in the besieged port city need a permit to move around - and a separate permit to leave.
Mr Boichenko also claims that around 2,000 men are being held in so-called “filtration centres” in Bezymenne and Kozatske, and not being allowed to return to their homes unless they are sick or injured.
“They are being used as labour to clear the rubble, collect the dead bodies of those the Russians have killed, and cover up evidence of war crimes,” he says.
The BBC has not independently verified these claims.
Capturing Mariupol - now dominated by Russian forces, aside from the Azovstal steelworks - will allow the Russians to complete a land bridge between Crimea and the Donbas region, as well as giving them full control of more than 80% of Ukraine's Black Sea coastline.
But in their quest to do so, they have pummelled Mariupol with artillery, rockets and missiles - damaging or destroying more than 90% of the city.
Once a thriving port with a promising future, Mr Boichenko shares a thick booklet of plans compiled last year for Mariupol. It's full of glossy images of parks, pavement cafes, universities and schools.
“I worked there for seven years, putting my heart and soul into it, " he tells the BBC.
"My home is there, my parents’ home is there. They took everything away from us, “ he says. “My heart and soul are gone.”

VE Day marked in shadow of Ukraine war
Germany's foreign minister has urged people to stand up for peace, freedom and democracy, on the day much of Europe celebrates VE Day, marking the anniversary of the defeat of Nazi German in World War Two.
Ahead of a planned visit to Ukraine, Annalena Baerbock said VE Day reminded Germans never again to be on the wrong side of the struggle for freedom and humanity.
Earlier on Sunday, Ukrainian President Volodymyr Zelenskiy gave an emotional Victory Day speech, saying that "evil has returned" to Ukraine, but Russia would not escape responsibility.
Russia will celebrate victory in WW2 on Monday, with the annual Victory Day parade in Moscow a centrepiece.
President Vladimir Putin sent messages to a number of pro-Russian leaders and their citizens on Sunday, as well the peoples of Georgia and Ukraine.
In his message to "the veterans of the Great Patriotic War and citizens of Ukraine", Putin stressed "the unacceptability of revenge on the part of the ideological followers of those who were defeated". He said it was the "common duty" of Russia, and her allies, "to prevent the revival of Nazism, which brought so much suffering to the people of different countries".
One of President Putin’s justifications for his invasion of Ukraine is that he wants to - in his words - "denazify" the country.

Video caption: Ukraine war: President Zelensky hits out at Russia's 'evil' invasion
Ukrainian President Volodymyr Zelensky has accused Russia of implementing "a bloody reconstruction of Nazism".
In a speech commemorating World War Two, he said the Russian army was replicating Nazi "atrocities" during its invasion of his country.
"Darkness has returned to Ukraine and it has become black and white again," he said in his video address.
"Evil has returned, in a different uniform, under different slogans, but for the same purpose," he added.
The video also featured archive footage of World War Two and black-and-white footage of Russia's invasion.
Mr Zelensky's references to Nazism appear to be an attempt to turn Vladimir Putin's language against him.
Russia has justified its offensive in Ukraine as a "special operation" to "demilitarise" and "de-nazify" its neighbour.

We're basically dead - fighter at besieged steel plant
Hugo Bachega
Reporting from Dnipro
This was a remarkable news conference, broadcast live online from a bunker in the partially destroyed Azovstal steelworks, the last pocket of Ukrainian resistance in the city of Mariupol.
First, Capt Svyatoslav Kalina Palamar, the deputy commander of the Azov regiment, said they had been under intense Russian shelling, and that the invading forces were trying to storm the plant. While hundreds of civilians had been evacuated in recent days, he said there was a "multitude of casualties" across the sprawling complex, both civilian and military.
Another fighter, Lt Illia Samoilenko, then spoke for almost two hours, most of it in English. He started by heavily criticising the government, without giving details, saying it had let 25,000 people be "murdered by the Russian army" in the city, a figure that cannot be independently verified.
"Nobody expected we would last so long and we’re still lasting, we’re still holding," he said, adding that they had been "left on their own for the last eight years". "Our government actually failed in the defence of Mariupol. Failed in the preparation."
Lt Samoilenko said he could not give details about how many fighters were still holed up in the site but said a "couple hundred" had been wounded. Russia, whose forces are surrounding the plant, says it could agree with the evacuation of the fighters if they lay down their arms, something rejected by Lt Samoilenko.
"Surrender for us is unacceptable because we can’t grant such a big gift to the enemy," he said. "We are basically dead men. Most of us know this. It’s why we fight so fearlessly."

US first lady Jill Biden made a surprise visit to Ukraine during a trip to Romania and Slovakia where she was reaffirming US support for Nato allies.
Mrs Biden met Ukraine's first lady Olena Zelenska at a school in the border town of Uzhhorod which is currently being used as temporary shelter for displaced people.
The US first lady said she wanted "to show that the people of the United States stand with the people of Ukraine" adding that the war, now it its third month, had been "brutal" and had to stop.
Mrs Zelenska said it had been a "courageous act" to visit Ukraine.
"We understand what it takes for the US first lady to come here during a war, when the military actions are taking place every day, where the air sirens are happening every day, even today,” she said.
She added that the visit, on Mother’s Day, was very symbolic, adding: "We feel your love and support during such an important day.”
Mrs Zelenska has not appeared in public since the Russian invasion began on 24 February.
The two women later sat down and played with some of the dozens of children who are currently housed at the school, making tissue paper bears - the symbol of the local province.

Canadian Prime Minister Justin Trudeau has made an unannounced visit to the Ukrainian town of Irpin, which came under heavy bombardment at the start of the invasion and was temporarily occupied by Russian forces.
Writing on Telegram, local mayor Oleksandr Markushyn, said Mr Trudeau came "to see with his own eyes all the horror which Russian occupiers have caused to our town".
Canada was one of the 12 founding members of Nato in 1949. It has committed over $118 million in military equipment to support Ukraine since the beginning of this year, according to the government there.

G7 leaders and Zelensky discuss sanctions
US President Joe Biden is currently meeting his G7 counterparts and Ukrainian President Volodymyr Zelensky - by video conference - as they consider new measures to punish Moscow for its invasion of Ukraine.
The White House said the leaders would discuss adding to the sanctions that Western countries have imposed on Russia since its 24 February invasion.
Washington said the leaders would discuss the latest developments in Russia's war against Ukraine and its global impact - and how nations could build on sanctions "to impose severe costs for Putin's war".

US announces further sanctions against Russia
New sanctions against Russia were announced in Washington on Sunday, as President Biden hosted a video call with other G7 leaders and President Zelensky.
As a further punishment for its unprovoked invasion of Ukraine, the US unveiled sanctions against three Russian television stations, banned Americans from providing accounting and consulting services to Russians, and sanctioned executives from Gazprombank.
The measures leveled against Gazprombank executives were the first involving the trading arm of the Russian gas giant.
The US and its allies have so far avoided imposing measures against the gas exporter's bank amid fears that it might lead to gas shortages for EU customers.
A senior White House official said the move was "not a full block" but was intended to signal that Gazprombank "is not a safe haven".
New export control restrictions were aimed at directly degrading Putin's war effort, including controls on industrial engines, motors and fans. In tandem, the EU will also impose additional controls on chemicals which contribute to the Russian military effort, the official said.
The White House also said the Nuclear Regulatory Commission would suspend licences for exports of special nuclear material to Russia.
