(NEW YORK) — Russian President Vladimir Putin’s “special military operation” into neighboring Ukraine began on Feb. 24, with Russian forces invading from Belarus, to the north, and Russia, to the east. Ukrainian troops have offered “stiff resistance,” according to U.S. officials.

The Russian military last month launched a full-scale ground offensive in eastern Ukraine’s disputed Donbas region, attempting to capture the strategic port city of Mariupol and to secure a coastal corridor to the Moscow-annexed Crimean Peninsula.

‘No reason to celebrate’ evacuations from besieged plant, commander says

As news spread of a successful evacuation operation from the besieged Azovstal steel plant in Mariupol, the deputy commander of the Azov battalion, Svyatoslav Palamar, said there was little reason to celebrate.

“Not enough is being done to try and evacuate wounded soldiers,” Palamar said, speaking at a press conference at the plant, which is surrounded by Russian forces.

Ukraine’s Deputy Prime Minister Iryna Vereshchuk said Saturday the first stage of the rescue operation had concluded and all civilians had been evacuated from the steel plant. Another 173 people were rescued Sunday from Azovstal and surrounding Mariupol, according to the local city council.

But Palamar said some civilians might still be trapped under the rubble of ruined shelters and that many bodies of deceased troops and civilians remain uncollected on the plant’s territory.

More than 25,000 people, most of them civilians, have been killed in Mariupol, according to Azov commanders. Half of all Russian bombardment and shelling in Ukraine was aimed at Mariupol, the battalion commanders said, adding that the city was shelled 150 times a day on average.

Russia has lost about 2,500 troops, with a further 500 wounded and over 60 destroyed tanks, in the city, Azov officials claimed. Yet the unblocking of Mariupol by military means remains difficult due to the lack of heavy weapons, Ukrainian President Volodymyr Zelenskyy said during a joint press conference with Canadian Prime Minister Justin Trudeau in Kyiv on Sunday.

Russia continued over the weekend to shell Ukrainian cities. Zelenskyy said Russians have “celebrated” the Day of Remembrance and Reconciliation on May 8 by launching nine missile strikes against Odessa. Zelenskyy spoke at a press briefing in Kyiv held after his talks with visiting Croatian Prime Minister Andrej Plenkovic. The Ukrainian President also met the head of the German parliament, Baerbel Bas, on Sunday. The two leaders spoke about how “German leadership in the European Union” can help Ukraine, Zelenskyy said in his nightly address on Sunday.

Ukrainian Foreign Minister Dmytro Kuleba tweeted Sunday that Berlin made a mistake by prohibiting Ukrainian symbols and flags at rallies during events on May 8-9.

“It’s deeply false to treat them equally with Russian symbols,” Kuleba wrote, adding that “taking the Ukrainian flag away from peaceful protestors is an attack on everyone who now defends Europe and Germany from Russian aggression with a flag in their hands.”

On Monday, as Ukraine celebrated the Day of Victory over Nazism in World War II, Zelenskyy said that the ongoing conflict was “not a war of two armies. This is a war of two worldviews.”

Russian missiles are trying to destroy Ukrainian philosophy, Zelenskyy said, because it “scares them.”

“We are free people who have their own path,” the president said. “Today we are waging war on this path and we will not give anyone a single piece of our land.”

Canadian Prime Minister Trudeau visits Ukraine, announces new support

Canadian Prime Minister Justin Trudeau visited Ukraine on Sunday and toured devastated areas in and around Kyiv with Ukrainian President Volodymyr Zelenskyy.

During a joint news conference, Trudeau pledged Canada’s continuing support for Ukraine and condemned Russian President Vladimir Putin for atrocities he alleged Russian forces are responsible for in Ukraine.

“It is clear that Vladimir Putin is responsible for heinous war crimes,” Trudeau said. “We will continue to do the work of being there for you with whatever we can, whatever you need.”

Trudeau announced that Canada is sending additional military support to Ukraine, including drone cameras, satellite imagery, small arms and ammunition.

The prime minister also said Canada will impose new sanctions on 40 Russian individuals he alleged are complicit in Putin’s war.

“And we’re bringing forward new sanctions on 40 Russian individuals and five entities, oligarchs and close associates of the regime in the defense sector, all of them complicit in Putin’s war,” Trudeau said.

Trudeau also announced that all trade tariffs on Ukrainian imports to Canada will be lifted for the next year and that Canada is donating CA$25 million, or about US$19.3 million, to the U.N. World Food Program, which is providing emergency food assistance to people in Ukraine.

Trudeau said that he and Larissa Galadza, Canada’s ambassador to Ukraine, raised the Canadian flag at the country’s embassy in Kyiv on Sunday to signal its reopening. He called the move an “important symbol not just of Canada’s steadfast friendship with Ukraine, but of the incredible resilience and heroism of the Ukrainian people, who ensured that this city did not fall.”

Pope Francis asks for daily prayer for peace in Ukraine

Pope Francis on Sunday prayed for peace in Ukraine, entrusting to the Virgin Mary the ”sufferings and tears of the Ukrainian people.”

”In front of the war’s madness, let us please continue to pray the rosary for peace every day,” the pope told thousands of people gathered in the Vatican’s St. Peter’s Square for his weekly address and blessing.

For several Sundays in a row the pope has led prayers for peace in Ukraine and has condemned the Russian invasion of the country, calling the act of war “senseless” during an Easter Sunday Mass last month.

The pontiff also prayed for the victims of an apparent gas explosion on Friday at the Hotel Saratoga in Havana, Cuba. At least 26 people were killed in the blast at the popular hotel and around 70 people were injured.

U2’s Bono, The Edge perform surprise concert in Kyiv

U2’s frontman Bono and lead-guitarist The Edge surprised fans in Kyiv on Sunday by performing an impromptu concert in the Ukrainian capital’s central metro station.

The two Irish rockers delivered a nearly hour-long set at the Khreshchatyk Metro Station, Kyiv’s busiest metro station, as several dozen fans watched.

“The people of Ukraine are not just fighting for your own freedom, you’re fighting for all of us who love freedom,” Bono told the crowd between songs.

The musicians were joined on one of the station’s platforms by Taras Topolia, frontman of Ukrainian pop rock band Antytila. Topolia presented Bono with a piece of shrapnel he said was the remains of a missile that struck near the base in Kyiv where he is currently serving in the Ukrainian Army.

(LONDON) — During a military parade in Moscow on Monday, Russian President Vladimir Putin addressed his troops fighting in neighboring Ukraine, but offered little insight into his next steps.

“You are fighting for the motherland, for its future, so that no one forgets the lessons of the Second World War,” Putin said in a patriotic speech for Victory Day, a national holiday in Russia commemorating the Soviet Union’s defeat of Nazi Germany in World War II.

Columns of Russian soldiers marched through Moscow’s Red Square, alongside tanks and other military vehicles boasting huge intercontinental ballistic missiles.

“Now here, on the Red Square, soldiers and officers from many regions of our vast homeland stand shoulder to shoulder, including those who came directly from Donbas, directly from the combat zone,” Putin said.

Putin launched a “special military operation” into neighboring Ukraine on Feb. 24, with Russian forces invading from Belarus, to the north, and Russia, to the east. They quickly reached the outskirts of Kyiv, but ultimately failed to seize the Ukrainian capital and other major cities in the north. Russian forces were met with strong resistance from Ukrainian troops, despite weeks of relentless bombardment that decimated entire neighborhoods and claimed civilian lives.

The Russian military announced on March 29 it would scale down activities in the north around Kyiv and Chernihiv and instead focus its efforts on the “liberation” of the disputed Donbas region in the east, which is home to a mostly Russian-speaking population. Russia-backed separatist forces have controlled two breakaway republics of eastern Ukraine’s Donetsk and Luhansk oblasts in Donbas since 2014, following Russia’s annexation of Ukraine’s Crimean Peninsula. On April 18, the Russian military began a full-scale ground offensive in Donbas in an attempt to capture the strategic port city of Mariupol and to secure a coastal corridor to Crimea.

Although he showed no signs of backing down, Putin on Monday did not make any declarations of war, peace or victory during his remarks. He drew parallels between Soviet soldiers battling Nazi troops and the Russian forces fighting now in Ukraine, as he has vowed to “de-Nazify” Ukraine. He also spoke of Donbas as if it was already part of Russia.

“These days, you are fighting for our people in the Donbas. For the security of our homeland, Russia,” he said. “You are defending what fathers and grandfathers, great-grandfathers fought for.”

Putin accused Ukraine of seeking to attain nuclear weapons and planning a “punitive operation in the Donbas, for an invasion of our historical lands, including Crimea.” He also laid blame on the West for refusing to have “an honest dialogue” about Russia’s demands for formal guarantees that Ukraine will never join NATO and that the alliance will pull back its forces from countries in eastern Europe that joined after the Cold War.

“Thus, an absolutely unacceptable threat was systematically created for us and directly at our borders,” Putin added. “The danger was growing everyday.”

The Russian leader claimed that attacking the former Soviet Republic “was a forced, timely and only right decision — the decision of a sovereign, strong, independent country.”

“Russia has given a preemptive rebuff to aggression,” he said.

Just hours before Putin’s remarks, Ukrainian President Vladimir Zelenskyy released a video message marking the 1945 victory over the Nazis, telling his country that “very soon there will be two Victory Days in Ukraine.”

“Today, we celebrate the Day of Victory over Nazism. And we will not give anyone a single piece of our history,” Zelenskyy said. “We are proud of our ancestors who, together with other nations in the anti-Hitler coalition, defeated Nazism. And we will not allow anyone to annex this victory, we will not allow it to be appropriated.”

“On the Day of Victory over Nazism, we are fighting for a new victory,” he added. “The road to it is difficult, but we have no doubt that we will win.”

(NEW YORK) — During its war in Ukraine, Russia’s top military leadership has proven to be particularly vulnerable, experts say.

Ukraine’s Ministry of Defense has claimed that 12 Russian generals have been killed since the invasion began in late February.

Russian officials have not confirmed that number. U.S. officials — who last week pushed back on a New York Times report that said the U.S. provided Ukraine intelligence that helped it target and kill Russian generals and other senior officers — also have not confirmed the number of Russian generals killed.

Though, as reported by Ukraine, that kind of loss is “quite extraordinary,” ABC News contributor and retired Col. Steve Ganyard said.

“Maybe you’d have to go back to World War II to have that sort of proportion of senior officers being killed on the front lines,” Ganyard said.

Lack of confidence in troops

Such a high number of casualties at that level suggests several things — one being a lack of confidence among Russian military leaders in their troops, according to Ganyard.

“It suggests that the generals need to be at the front lines to ensure that their troops are conducting the battle plan in the way that they want,” he said. “But that also suggests a lack of confidence in their troops if they need to be that far forward with that many senior folks.”

That demonstrates Russia’s seriousness about its campaign but is also “an indication of how weak the Russian military has turned out to be in that they need that much senior leadership that far forward,” Ganyard said.

Russian generals also may be especially vulnerable due to the structure of Russia’s military, experts say.

Unlike the U.S. military, Russia does not empower its non-commissioned and junior officers with the authority to make decisions on their own, said Mick Mulroy, a former deputy assistant secretary of defense for the Middle East and an ABC News contributor.

“They do not delegate authority. So, they are out giving orders directly to their forces,” Mulroy said. “The lack of delegation is another reason the Russian military is performing so poorly.”

Poor morale among Russian troops may also be giving Ukraine an advantage in the war, despite Ukrainians being outnumbered by enemy troops and military equipment, Ganyard said.

“As soon as communication breaks down … the young folks in the Russian military don’t know what to do and they know that they’re just being told to do something, particularly when it’s a fight where their heart isn’t in it,” he said. “That is an advantage that Ukraine has proven to be decisive on the battlefield thus far.”

Vulnerable command and control capabilities

Russian troops have also been shown to be vulnerable to electronic eavesdropping while on the ground in Ukraine, Ganyard said.

“One of the many failures of the Russian military in this war is that it has shown how little they have invested in command and control capabilities,” he said. “The Russians aren’t even using encryption, so it means that anybody — if they find the frequency — are able to listen in.”

There are “very credible reports” of Russian troops even confiscating phones from Ukrainian citizens and using those for command and control operations, Ganyard said.

“So obviously, the Ukrainians can tap into their own phone lines if they can figure out who’s doing it,” he said.

Russian soldiers have also been tracked in real-time through geolocation of social media posts, Ganyard said.

“The modern age has introduced lots of benefits, but in the case of the military, it actually becomes dangerous because most of the apps that people are running are not encrypted and they’re passing real-time data of where people are,” he said.

Tracking Russian troops could lead Ukrainian forces to command posts — and likely top military leadership.

“If you shell and you take out a command post, you’re probably going to take out quite a bit of senior leadership,” Ganyard said.

Amid the claims of Russia’s military leadership losses, it is unclear what the Ukrainian military has similarly suffered.

“The Ukrainians have been very good at controlling the narrative on social media and on media in general,” Ganyard said. “We’re getting anecdotal reporting back-channel that the Ukrainians are paying a price, too.”

And with a smaller military, the Ukrainians “can pay a price less than the Russians can,” he added.

“The Ukrainians are hurting,” Ganyard said. “This is not something where the Ukrainians are not taking any losses, while the Russians are.”
