More than half of Ukrainians are at risk of developing mental health problems, Kyiv says
The Ukrainian government estimated that more than half of Ukraine's population is at risk of developing mental health problems due to Russia's ongoing war.
The government in Kyiv has previously said that Russian shelling of civilian infrastructure, like healthcare facilities, adds to the challenges facing individuals seeking mental health support. Russia has previously denied that its forces in Ukraine target civilian infrastructure or commit war crimes.
In December, the World Health Organization said that 10 million people, or about a quarter of Ukraine's population, may suffer from a mental health disorder in relation to the conflict.
"WHO estimates that up to 10 million people are at risk of some form of a mental disorder, varying from anxiety and stress to more severe conditions," Jarno Habicht, the WHO's representative in Ukraine said in December.

Ukraine using Soviet-era choppers to pummel Russia from afar
Skimming the treetops, three Soviet-era attack helicopters bank and swoop down on a field after an early-morning mission to the front lines in the fight against Russia's invasion of Ukraine.
Each day, they might fly three or four sorties, says the commander, whose two-crew Mi-24 helicopter, built about 40 years ago, is older than he is.
"We are carrying out combat tasks to destroy enemy vehicles, enemy personnel, we are working with pitch-up attacks from a distance from where the enemy can't get us with their air defense system," said the commander, who spoke on condition of anonymity for operational security reasons, in line with military regulations.
The conflict in Ukraine is largely an artillery war, with territory being fought for inch by inch under a barrage of shells and missiles. But Ukraine's aviation capabilities play a significant role in the fight, the pilot said.
"The importance of the helicopters is huge," said the commander, who is part of Ukraine's 12th Army Aviation Brigade.
Footage from a camera attached to the helicopter during a recent combat mission shows it flying over fields pockmarked with craters from artillery bombing, and firing missiles at Russian trenches that cut through the landscape.

Ukraine's first lady launches mental health program
Ukraine's first lady launched a program dubbed "How Are You," to promote mental health as her country fights off a full-scale Russian invasion.
"Against the background of daily alarming news, missile attacks, human grief and trouble, it doesn't seem appropriate to ask yourself, "How are you? But in fact, psychological well-being and understanding of what is happening in our inner world is more timely than ever," Olena Zelenska said in a Ukrainian government release.
"The battle with pain, past traumatic experience is an invisible front where we also have to win. The weapon in this battle is daily care for mental health, which is an inseparable whole with physical health," Zelenska added.

EU officials announce initiative to repatriate Ukrainian children
European Union Commission President Ursula von der Leyen announced that she and Polish Prime Minister Mateusz Morawiecki will work with Ukrainian officials as part of a mission to bring home Ukrainian children taken out of the country by Russia.
"Deporting children is a war crime. In partnership with the Ukrainians, Prime Minister @MorawieckiM and I have launched an initiative aimed at repatriating Ukrainian children abducted by Russia," von der Leyen wrote in a post on Twitter.
Ukrainian and Western officials allege that Russian forces have moved at least 6,000 Ukrainian children to camps and facilities across Russia for forced adoptions and military training.
A report published in February by the Conflict Observatory at Yale University's Humanitarian Research Lab, entitled "Russia's systematic program for the re-education and adoption of Ukraine's children," outlines what it calls the Kremlin's systematic efforts to abduct children, prevent their return to Ukraine and "re-educate" them to become pro-Russia.
Russia has repeatedly denied its troops have committed war crimes or deliberately targeted civilians in attacks, and the Russian Embassy in Washington called the report's allegations "absurd."

The death toll in Kostiantynivka in eastern Ukraine's Donetsk region after Russian overnight attacks rose to five on Friday afternoon, counting two men and three women, Ukraine's State Emergency Service reported via Facebook.
"On the night of March 24, the city of Kostiantynivka came under missile attack," the post read, according to a translation by Ukrainian state news outlet Ukrinform.

Several civilians killed in overnight Russian strikes: Ukrainian news agency
Several people were killed in Russian strikes on different parts of Ukraine overnight, Ukrainian state broadcaster Suspilne reported. The attacks used Iranian-made "Shahed" drones and fighter jets, the agency said.
"At night, Russian troops shelled a "point of invincibility" in Kostyantynivka, Donetsk region. Three resettled women from other settlements of the region died under the rubble, and two more people were injured," Suspilne wrote in a Telegram post, according to a Google translation.

Two people were killed in the city of Bilopillya, nine others were injured. In Kryvyi Rih, Dnipropetrovsk oblast, there were five hits by "Shahed" drones. Air defense forces managed to shoot down one," the post read.

Russia likely to keep training forces under 'much less experienced' Belarusian army, UK says
Russia's troop movements in Belarus suggest that it is continuing a training program in the country with Belarusian forces, despite the latter's military being far less experienced, Britain's Ministry of Defense wrote in its daily intelligence update on Twitter. Retaining a training ground there also conveys important political messaging, it said.
"As of mid-March 2023, Russia had likely redeployed at least 1,000 troops who had been training at the Obuz-Lesnovsky training ground in south-western Belarus," the ministry wrote.
"Although no new rotation of troops has been noted, Russia has highly likely left the tented camp in place, suggesting it is considering continuing the training programme," it noted.
"The fact Russia has resorted to training its personnel under the much less-experienced Belarusian army highlights how Russia's 'special military operation' has severely dislocated the Russian military's training system – instructors have largely been deployed in Ukraine."

China's plan to end the war in Ukraine is 'unfair,' Estonia says
China's peace proposal to end the war in Ukraine is "extremely unfair," the permanent secretary of Estonia's Ministry of Defense told CNBC.
Beijing's 12-point peace plan doesn't respect Ukraine's territorial integrity and hasn't been fair to its people, Kusti Salm told CNBC's "Squawk Box Asia" on Friday.
"Whenever we measure … the feasibility of any peace deal, it needs to be measured against the same principles. Are we outrooting the aggression as a tool?" he asked.
"Are we honoring the territorial integrity and sovereignty of independent nations?"
Those are the "key ingredients and elements missing" from China's peace proposal, he said.
Chinese President Xi Jinping's three-day visit to Russia concluded on Wednesday, but failed to make any meaningful breakthrough in resolving Ukraine's conflict.

Zelenskyy calls on EU to continue supporting Ukraine, imposing pressure on Russia
Ukrainian President Volodymyr Zelenskyy warned that if Europe hesitates in supporting Ukraine, "evil may have time to regroup and prepare itself for years of war."
"It is in your power not to allow this to happen," Zelenskyy said in a sweeping speech before members of the European Council.
The Ukrainian president also reiterated calls for more military aid from European leaders.
"The more often Ukrainian cannons hit the occupier – the less chance Russia has to implement its genocidal policy against Ukrainians and other Europeans," Zelenskyy said.
"God forbid anyone should see it happen in his or her own country," he added.
Zelenskyy also thanked members of the European Union that support the work of the International Criminal Court in holding Russian President Vladimir Putin to account for the ongoing war in Ukraine.

Ukraine signals counterattack is coming as Wagner mercenaries take a hit
Ukraine's most senior ground forces commander said the country's forces will launch a much-anticipated counteroffensive "very soon" just as Russian forces are seen to be losing momentum in Donetsk in eastern Ukraine.
Colonel-General Oleksandr Syrskyi said on Telegram Thursday that Russian forces have not given up "hope of taking Bakhmut at any cost, despite the losses in manpower and equipment," noting that the main Russian units taking a hit were mercenaries in the Wagner Group.
"Without sparing anything, they lose considerable strength," he said, adding that "very soon we will take advantage of this opportunity, as we once did near Kyiv, Kharkiv, Balakliya and Kupiansk," he said, according to comments translated by Google.
The comments come as military analysts view Russia's offensive around Bakhmut in eastern Ukraine as losing momentum after seven months of brutal, incessant fighting that has left Bakhmut largely in ruins and thousands of soldiers dead on both sides, estimates of daily fatalities suggest.
Ukraine has previously signalled that it would launch a counter-offensive in spring but has also been waiting for the arrival of more Western weaponry.
Syrskyi said soldiers on the front line in Bakhmut had demonstrated "superhuman resilience, courage and bravery" in the face of "continuous fire of the enemy's artillery and aircraft."

A look at the uranium-based ammo the UK will send to Ukraine
Russia threatened to escalate attacks in Ukraine after the British government announced it would provide to Ukraine a type of munition that Moscow falsely claims has nuclear components.
The British defense ministry on Monday confirmed it would provide Ukraine with armor-piercing rounds containing depleted uranium.
Such rounds were developed by the U.S. during the Cold War to destroy Soviet tanks, including the same T-72 tanks that Ukraine now faces in its push to break through a stalemate in the east.
Depleted uranium is a byproduct of the uranium enrichment process needed to create nuclear weapons. The rounds retain some radioactive properties, but they can't generate a nuclear reaction like a nuclear weapon would, RAND nuclear expert and policy researcher Edward Geist said.
That didn't stop the Russians from offering a full-throated warning that the rounds were opening the door to further escalation. In the past, they have suggested the war could escalate to nuclear weapons use.
Both the the British ministry and the White House dismissed the Russian accusations. But the ammunition does carry risks even if it's not a nuclear weapon.
