In an open letter to Russian President Vladimir Putin, Ukrainian President Volodymyr Zelenskyy proposed meeting to reach a resolution to the years-long war between their two nations.

"We see that the United States is fully focused on the issue of Iran, and it would be wrong to simply wait until the war in Europe returns to the center of its attention. Ukraine proposes ending this war through direct engagement between us — and you. I am proposing a meeting," Zelenskyy said in the letter.

"There are countries that have traditionally hosted leaders to resolve issues of war and peace. Switzerland, Türkiye, the countries of the Arab world — many are able and willing to host such a meeting. It is leaders who resolve the key issues. That has always been the case, and it always will be," he asserted.

Zelenskyy suggested that Europe and the U.S. should also be involved in the peace process.

"Since the war is taking place in Europe, and since Ukraine needs security guarantees, while you also seek security guarantees for yourself, it would be logical to involve those who can genuinely serve as guarantors. We believe Europe should be part of this process — those who truly have the capacity to influence the situation. We also believe that the United States must be part of the process. This is what could help shape a new security architecture for our part of the world," he said.

He indicated that Ukraine would agree to a ceasefire during the proposed negotiations.

"Ukraine is ready for a full ceasefire for the duration of the negotiations. This is standard practice, and current developments around Iran only reinforce that point. An attempt to establish real silence is the best way to begin talking to one another. We believe it would not simply be an attempt, but a real ceasefire — if that is what you want," he noted.

He also suggested a prisoner swap between the two nations, noting, "Ukraine is ready for an all-for-all exchange of prisoners of war, and this could become a good prologue to ending the war. Serious steps must be taken to return civilians and children who were taken away during the war."

"If you do not personally come to the conclusion that it is time to end this war, Ukraine will continue fighting for its existence. We will have those who support us. But you, too, will have to fight much harder for your own existence — not Russia’s, but your own. And this is not a threat from me or from Ukraine. It is a fact of Russian history that you know well: when Russia grows tired, change comes," Zelenskyy warned Putin.

A drone struck an apartment building Friday in Romania, a NATO member, causing an explosion and fire that injured multiple people, local authorities said.

According to Romania’s Ministry of Defense, the incident occurred as Russia carried out an overnight drone attack in neighboring Ukraine near the Romanian border.

"A drone entered Romanian airspace, was tracked by radar systems as far as the Southern area of Galați municipality, and crashed onto the roof of a residential apartment building," the ministry said.

Romania — a member of both NATO and the European Union — has reported more than two dozen incidents involving Russian drones entering its airspace since Moscow launched its invasion of Ukraine.

Friday’s incident marked the first time a drone struck a populated area in Romania, resulting in injuries.

Romania’s state news agency reported that a woman and her child were hospitalized with minor injuries, while two other people were treated at the scene for panic attacks.

Following the incident, Romania requested additional anti-drone capabilities from NATO and described the drone’s flight path as a serious violation of international law, according to The Associated Press.

Romania’s emergency response agency said the drone struck the apartment building and exploded, sparking a fire on the 10th floor.

The agency said the drone’s entire explosive payload detonated upon impact.

Seventy people were evacuated from the building, authorities said. The fire has since been brought under control.

NEW ROMANIAN LAW MAY HAVE AVERTED NATO CLASH WITH RUSSIA AFTER BORDER STRIKES

The defense ministry said two F-16 fighter jets and a military helicopter were deployed to monitor the Russian attack. The pilots were authorized to shoot down any drones that posed a threat.

The incident came after Ukrainian President Volodymyr Zelenskyy said earlier this week that he was pressing the United States to provide additional Patriot air defense missiles to help counter Russian attacks.

He warned that deliveries to Ukraine were falling dangerously short as the conflict with Iran strains U.S. military resources and stockpiles.

"I believe [the U.S.] must act quicker. We are being very persistent," Zelenskyy told reporters during a visit to Sweden.

Reuters and The Associated Press contributed to this report.

This is part three of a series examining the challenges confronting the NATO alliance.

LVIV, Ukraine — Four years into Russia’s invasion of Ukraine, officials across NATO’s eastern flank increasingly believe the alliance’s future is already being rewritten on Ukraine’s battlefield.

From drone warfare and cyber defense to civilian resilience and large-scale military mobilization, Eastern European officials say Ukraine has become one of the world’s most battle-tested militaries, forcing NATO to rethink how future wars will be fought.

This week, NATO Secretary-General Mark Rutte confirmed Ukrainian President Volodymyr Zelenskyy had been invited to attend the alliance’s annual summit in Ankara in July, underscoring how central Ukraine has become to NATO’s future despite not being a member of the alliance.

'A NEW KIND OF WAR': INSIDE UKRAINE'S HIDDEN FACTORIES MASS-PRODUCING COMBAT DRONES

"I think today the Ukrainian army is the number one army in Europe," Mayor of Lviv Andriy Sadovyi told Fox News Digital during an interview in the western Ukrainian city.

"I think NATO needs the Ukrainian army," he added.

The debate over NATO’s future intensified this week as alliance foreign ministers gathered in Sweden ahead of a major NATO summit in July, with Secretary of State Marco Rubio calling the upcoming meeting "one of the more important leaders’ summits in the history of NATO."

Rubio warned NATO allies this week that the alliance lacks sufficient munitions production for future conflicts, a concern echoed by retired Lt. Gen. Richard Newton, who said the Pentagon is studying Ukraine’s rapid wartime industrial adaptation.

"A number of nations are taking a page out of Ukraine’s transformation of its defense industrial base, in terms of quality as well as the tremendous increase in quantity of arms to the frontlines as well," Newton said, adding, "The Pentagon is taking note and working to encourage the transformation of our own industrial base so we can drastically improve and more rapidly provide capabilities to our forces in the field, not in a matter of years but in months and perhaps even in weeks."

Rubio also referenced President Donald Trump’s announcement that the U.S. would maintain troop deployments in Poland after concerns earlier this week about possible reductions on NATO’s eastern flank.

AS TRUMP FORCES NATO TO PAY UP, ALLIANCE RACES TO CLOSE MILITARY GAP WITH US

Speaking before the NATO meeting, Polish Foreign Minister Radosław Sikorski welcomed Trump’s announcement. "I want to thank President Trump for his announcement that the presence of American troops in Poland will be maintained more or less at previous levels," Sikorski said.

"I think this makes Putin very uncomfortable."

Some note that the debate over NATO’s future comes with deep irony for Moscow.

One of Russian President Vladimir Putin’s central grievances before the invasion was NATO’s eastward expansion and Ukraine’s growing ambitions to move closer to the alliance. Moscow repeatedly demanded NATO roll back its military footprint to pre-1997 levels and opposed any future Ukrainian membership.

Instead, the invasion accelerated NATO’s expansion.

Finland formally joined NATO in 2023, ending decades of military nonalignment, while Sweden joined in 2024 after Russia’s invasion dramatically reshaped security calculations across northern Europe. Finland alone added more than 800 miles of direct NATO border with Russia.

Now officials in Poland and Ukraine say the war is not only expanding NATO geographically, but fundamentally transforming the alliance itself.

"For decades, NATO focused largely on expeditionary wars and counterterrorism," said Polish Deputy Defense Minister Paweł Zalewski during an interview in Warsaw. "Modern warfare is mostly done by drones."

"There is not a military in the world which is better than Ukraine" in understanding today’s battlefield realities, he added.

US SCRAMBLES AS DRONES SHAPE THE LANDSCAPE OF WAR: 'THE FUTURE IS HERE'

Retired Gen. Philip Breedlove, who served as NATO supreme allied commander Europe, said the war has fundamentally transformed how militaries around the world understand modern warfare.

"The war in Ukraine has changed far more than just NATO’s understanding of modern warfare — it has changed the whole world’s understanding," Breedlove told Fox News Digital.

Breedlove added that Ukraine’s military has evolved into "one of Europe’s most capable and formidable" forces after years of fighting Russia, despite having surrendered its Soviet-era nuclear arsenal under the 1994 Budapest Memorandum.

UKRAINE MAKES FASTEST GAINS IN YEARS AS RUSSIA TALKS STALL, EXPLOITING CRACKS IN KREMLIN COMMAND

"Today, most agree that Ukraine is not only fighting, but winning back land against one of the world’s most formidable forces," he said.

That transformation is visible throughout Ukraine.

Before Russia’s invasion, Ukraine had one of Eastern Europe’s largest IT sectors. Sadovyi said the war forced much of that technological ecosystem to pivot toward defense production.

"Before the invasion, we had in Kyiv a huge IT cluster, 40,000 workers," Lviv’s mayor said. "During the war, we rebuilt the IT cluster to defend cluster."

Ukraine now operates a rapidly expanding wartime innovation ecosystem focused on drones, anti-drone systems, battlefield communications and decentralized weapons production. NATO officials and European militaries are increasingly studying those lessons closely.

Breedlove says the conflict exposed the limits of traditional air power and accelerated the rise of drone warfare.

"It’s critical to remember that the war in Ukraine is being fundamentally fought without the support of modern air warfare because of the failures of the Russian Air Force," he said.

"It’s why drone warfare has grown so exponentially, because neither side was able to marshal true modern air capabilities."

The changes are also reshaping NATO strategy.

The Polish defense official Zalewski told Fox News Digital the Pentagon is now promoting what Polish officials describe as "NATO 3.0," a model in which Europe assumes greater responsibility for conventional defense as the United States shifts more attention toward China and the Indo-Pacific.

"The main assumption of this concept is that conventionally it would be Europe defending itself," he said.

EUROPE STEPS UP TO FUND ITS OWN DEFENSE, PROVIDE SECURITY FOR UKRAINE AFTER TRUMP THREATS

That shift comes as Poland dramatically increases military spending and positions itself as one of NATO’s leading military powers on the alliance’s eastern flank. Warsaw spent nearly 5% of GDP on defense this year, the highest level in NATO.

Polish officials argue the war proved Eastern Europe was right to take Russia’s threat seriously long before many Western European countries did.

"The eastern flank is much more powerful than even five years ago," Polish Deputy Foreign Minister Marcin Bosacki told Fox News Digital during reporting in Warsaw.

"We were right about the nature of Putin’s regime and Russia’s aggressive strategy."

Ukraine is not currently a NATO member, and the alliance has avoided offering Kyiv a concrete timeline for accession during the war out of concern it could trigger direct confrontation between NATO and Russia.

But across Eastern Europe, officials increasingly argue the alliance’s future may depend on Ukraine regardless of formal membership.

Russian President Vladimir Putin on Saturday said he thinks the war with Ukraine could end soon.

"I think that the matter ⁠is coming to an end," Putin told reporters, according to Reuters.

Putin’s words came a day after Trump announced a three-day ceasefire to celebrate the Soviet Union’s victory in World War II, as well as a massive prisoner exchange between both nations.

The ceasefire began on Saturday and will run through Monday, Trump wrote on Truth Social. "The celebration in Russia is for Victory Day but, likewise, in Ukraine, because they were also a big part and factor of World War II."

TRUMP ANNOUNCES SURPRISE THREE-DAY CEASEFIRE IN RUSSIA-UKRAINE WAR

"This ceasefire will include a suspension of all kinetic activity, and also a prisoner swap of 1,000 prisoners from each country," he added. "This request was made directly by me, and I very much appreciate its agreement by President Vladimir Putin and President Volodymyr Zelenskyy."

The day was celebrated with Russia’s most scaled-back Victory Day parade in years.

The war in Ukraine has dragged on for more than four years after Russia invaded the country in February 2022, with the Kremlin initially believing it could win quickly yet Russia still hasn’t been able to take the entire Donbass region.

Putin told reporters that he would prefer to talk to former German Chancellor Gerhard Schroeder when asked about talks with European leaders.

He added that he would only consider speaking with Ukrainian President Volodymyr Zelenskyy after a lasting peace deal had been agreed upon.

On X, Zelenskyy confirmed the exchange of prisoners captured during the four-year conflict, which began when Russia launched a full-scale invasion of its neighbor.

"Within the framework of the negotiating process mediated by the American side, we received Russia’s agreement to conduct a prisoner exchange in the format of 1,000 for 1,000," he wrote. "A ceasefire regime must also be established on May 9, 10, and 11. Ukraine is consistently working to bring its people home from Russian captivity. I have instructed our team to promptly prepare everything necessary for the exchange."

Zelenskyy also thanked Trump for his diplomatic involvement in the process and said he hopes the United States will make sure Moscow abides by the agreement. 

Fox News' Louis Casiano contributed to this report.

Russian drone and missile strikes on Tuesday killed at least 22 people and wounded more than 80 across Ukraine, just hours before Kyiv had planned a ceasefire and days ahead of a pause announced by Moscow.

Glide bombs struck the Ukrainian cities of Kramatorsk, Zaporizhzhia, and Chernihiv on Tuesday afternoon, killing at least 17 civilians and injuring 45. Overnight attacks left five people dead and 39 wounded, according to The Associated Press.

"Absolute cynicism — to demand silence for holding propagandistic celebrations and then deliver such missile and drone strikes on all the days leading up to it," Ukrainian President Volodymyr Zelenskyy wrote on X.

Zelenskyy added that Russia could end the war at any time.

"Every day, Russia could cease fire, and that would stop the war and our responses. Peace is needed, and real steps are required for it. Ukraine will act in kind," he said.

Russia’s Defense Ministry previously said it would impose a unilateral ceasefire on Friday and Saturday for Victory Day, but warned it would retaliate if Ukraine disrupts events, The Associated Press reported.

The United Nations welcomed the moves, with Secretary-General António Guterres urging a full ceasefire.

Guterres called for "a full, immediate, unconditional and lasting ceasefire, leading to a just, comprehensive, and sustainable peace, in line with the U.N. Charter, international law and relevant U.N. resolutions," The Associated Press reported.

Victory Day, observed each year on May 9 in Russia, marks the Allied victory over Nazi Germany.

Russia has previously announced short holiday truces — most recently for Orthodox Easter — but they have failed to hold amid persistent mistrust between the two countries.

During that ceasefire, Ukraine’s military reported more than 2,200 violations, including shelling, assaults and drone activity. 

Russia’s Defense Ministry, in turn, accused Ukrainian forces of nearly 2,000 breaches, including strikes in border regions that it said injured civilians.

Fox News Digital's Stephen Sorace and The Associated Press contributed to this report.

A Russian gunman was killed by special forces Saturday in Ukraine after opening fire at a supermarket in Kyiv, killing six people and wounding 14 others — including a 12‑year‑old boy.

The 58-year-old shooter long resided in the Donetsk region and was born in Moscow, according to Ukrainian President Volodymyr Zelenskyy and Interior Minister Ihor Klymenko.

He took at least four hostages, killed one of them, and fatally shot four others on the street, Zelenskyy said. Another woman died at a hospital from her injuries.

Graphic video captured by witnesses showed the gunman shooting at a victim within close range on the street. Other bodies were seen lying on the pavement and in courtyards.

Ukranian special forces stormed the convenience store after 40 minutes of failed negotiations, according to Klymenko.

At least fourteen people were wounded in the attack, though officials cautioned the number may rise as people continue to seek medical assistance.

Among the injured is a 12‑year‑old boy and a supermarket security guard, according to Kyiv Mayor Vitali Klitschko.

Zelenskyy said the shooter also set fire to an apartment prior to the attack, though it is unclear if any injuries resulted from the arson.

"My condolences to the families and loved ones of the victims," Zelenskyy wrote in an X post. "...We wish all the wounded a swift recovery."

The gunman had previously been prosecuted for criminal offenses, but held a valid weapons permit, according to authorities. Investigators from the National Police and the Security Service of Ukraine are investigating.

Ukraine’s security service labeled the attack an act of terrorism.

"All available information about him and the motives behind his actions is being thoroughly investigated," Zelenskyy said. "Every detail must be verified."

One of the shooter's neighbors, Hanna Kulyk, 75, described him as an "educated, refined man," who lived alone and did not socialize often.

"You’d never guess he was some kind of criminal," Kulyk told The Associated Press.

Russia hammered civilian areas of Ukraine with hundreds of drones and dozens of missiles in an attack that stretched for hours from daytime into the night, killing at least 16 people and injuring more than 80 others as terrified residents cowered in their homes, officials said Thursday.

Russia launched nearly 700 drones and dozens of ballistic and cruise missiles, primarily targeting civilians, in its biggest aerial barrage in almost two weeks, authorities said.

Tetiana Sokol, a 54-year-old resident of Kyiv, said two missiles hit near her home and she took cover with her dog in the hallway as flashes lit up the night and windows shattered from the blast wave.

"On the third attack, everything broke, everything flew, we were shocked, we didn’t know where to run. I grabbed whatever came to hand and ran away with the dog," she told The Associated Press. "I still can’t find the cats in the house, they climbed out somewhere, I don’t even know. No windows, nothing, the dog is still walking around in stress."

Moscow's forces have hit civilian areas almost daily since its all-out invasion of its neighbor more than four years ago, with the regular assaults occasionally punctuated by massive attacks. More than 15,000 Ukrainian civilians have died in the strikes, the United Nations says.

Zelenskyy on a mission to improve air defenses

The latest bombardment came in the wake of Ukrainian President Volodymyr Zelenskyy's 48-hour trip this week to Germany, Norway and Italy in an urgent search for more air defense systems that can stop Russian missiles.

Ukraine has developed a significant domestic arms industry, especially in the production of drones and missiles, but it can’t yet match the sophistication of U.S. Patriot air defense systems. Ukraine’s top diplomatic priority is securing allies’ help to buy and build more and better air defenses, Zelenskyy said this week.

Cash-strapped Ukraine also needs the speedy disbursement of a promised loan from the European Union of 90 billion euros ($106 billion) that has been blocked by Hungary.

Ukraine fears the Iran war is burning through stockpiles of the advanced American-made systems it needs, and has argued against a U.S. temporary waiver on Russian oil sanctions that Kyiv says is helping finance the Kremlin's war effort.

"Another night has proven that Russia does not deserve any easing of global policy or lifting of sanctions," Zelenskyy said on X.

He thanked Germany, Norway and Italy for new agreements this week on supporting Ukraine's air defense. Officials are also working with the Netherlands on additional supplies, he said.

At the same time, he noted that some partner countries haven't followed through on pledges of military support.

"I have instructed the Commander of the Air Force to contact those partners who earlier committed to providing missiles for Patriot and other systems," Zelenskyy said.

Other areas of Ukraine and Russia were also hit

The bombardment was the biggest in weeks. Last month, Russia fired 948 drones and 34 missiles in the space of 24 hours in the largest assault of the war on civilian areas.

At least four people were killed overnight in Kyiv, including a 12-year-old, with more than 50 others injured, according to authorities. Officials said the attack damaged 17 apartment buildings, 10 private homes, as well as a hotel, office center, car dealership, gas station and a shopping mall in the capital.

Nine people were killed and 23 injured in the southern port city of Odesa, three women were killed and around three dozen injured in the central Dnipro region, and one person was killed in Zaporizhzhia in the south.

"Such attacks cannot be normalized. These are war crimes that must be stopped and their perpetrators held to account," Ukraine’s Foreign Minister Andrii Sybiha said on X.

Ukraine’s air force said air defenses shot down or disabled 667 out of 703 incoming targets, including 636 Shahed-type drones and other uncrewed aerial vehicles.

It said 20 strike drones and 12 missiles hit 26 locations.

Meanwhile, in Russia, Krasnodar regional Gov. Veniamin Kondratyev reported that a 14-year-old girl and a woman were killed in Ukrainian strikes in the Black Sea port of Tuapse.

He said that the attacks damaged six apartment buildings, 24 private houses and three schools. Drone fragments also fell near the port of Tuapse.

Russia’s Defense Ministry said that its air defenses downed 207 Ukrainian drones overnight.

Ukraine’s allies pledged a massive new military aid package Wednesday, including 120,000 drones from the U.K., after Russia launched hundreds of drones and ballistic missiles in fresh overnight strikes.

The commitments came as Kyiv warned of escalating Russian bombardments and urgently pressed for more air defenses.

Russia launched 324 drones and three ballistic missiles at Ukraine overnight Wednesday, Ukrainian officials said, part of a broader surge in aerial assaults, according to Reuters.

Russian strikes hit more than a half a dozen areas of Ukraine behind the front line on Tuesday and Wednesday, The Associated Press reported.

Between November and March alone, Moscow fired roughly 27,000 Shahed-type drones, nearly 600 cruise missiles and 462 ballistic missiles, according to Ukrainian Defense Minister Mykhailo Fedorov.

"Every day we need air defense missiles — every day Russia continues its strikes," Zelenskyy said in a post on Telegram.

The latest attacks struck multiple regions behind the front lines, killing an 8-year-old boy in the central Cherkasy region and injuring a woman in southern Zaporizhzhia, according to Ukrainian officials.

The war, which began with Russia’s full-scale invasion in February 2022, has now stretched beyond three years.

Defense leaders from about 50 countries met virtually Wednesday to coordinate military aid and boost weapons production and especially air defense systems.

The session was led by German Defense Minister Boris Pistorius and British Defense Secretary John Healey, with NATO Secretary General Mark Rutte also present. The United States was represented by Under Secretary of Defense for Policy Elbridge Colby.

Several countries also announced new contributions to Ukraine. Germany and Ukraine agreed on a 4 billion euro ($4.7 billion) defense package, while Norway pledged 9 billion euros (about $10.6 billion) in assistance.

The Netherlands said it will spend 248 million euros ($293 million) to produce drones for Ukraine. The United Kingdom pledged 120,000 drones.

Russia pushed back on the expanded support, warning that European efforts to boost drone production for Ukraine risk deepening their involvement in the conflict.

The Russian Defense Ministry said the decision by European countries to supply drones to Ukraine was leading to an escalation of the military-political situation and a "creeping transformation" into Ukraine’s strategic support base, TASS reported.

Ukrainian President Volodymyr Zelenskyy announced Monday that Ukraine had captured a Russian position using an entirely unmanned robot ground force.

"For the first time in the history of this war, Ukrainian warriors captured an enemy position using exclusively unmanned platforms," he said during a speech to weapons manufacturers on Ukraine's Arms Makers' Day.

"The future is here, on the battlefield, and Ukraine is creating it," he said in a video posted to X by a Ukrainian journalist.

The offensive, which took place in an unspecified location, was operated through drones and a grid-based robotic system (GRS) platform, an unmanned defense system.

Zelenskyy claimed that such autonomous systems have participated in over 22,000 frontline missions in just three months.

Machines used included the TerMIT, a multifunctional ground robotic system designed to lay mines, and provide fire support; the Zmiy, a next-generation armored robotic platform developed for cargo transport; and the Protector, a heavy unmanned ground system.

Zelenskyy also touted his country's use of drones, an integral cog in Ukraine's war plan.

"Our missiles, our unmanned systems, our interceptors, attack and naval drones, reconnaissance systems, artillery, our ammunition, armored vehicles, robotic platforms, and much more. All that today is truly proudly called – the weapons of Ukraine," the president added.

"They defend our skies, our cities and villages, save lives, and prove that 'Made in Ukraine' is synonymous with effectiveness and strength," he concluded.

Experts and commentators pointed to the growing use of unmanned technology as a turning point in the way wars are fought.

"So, if this starts happening at scale - which is the logical conclusion - would this change the nature, rather than the character, of war folks?" Dr. Patrick Bury, a senior professor of warfare and counter-terrorism at the University of Bath, wrote on X.

"I’m not sure the world is fully ready for when ground invasions can be accomplished by Black Mirror robot dogs," wrote Mike Benz, a former Deputy Assistant Secretary at the U.S. State Department. "'Boots on the ground' will no longer carry the political risk of sending 'our boys' out to fight. The temptation for robot-only ground invasions could be… enormous," he finished.

Benz reference to robot dogs highlights Ukraine's previous use of autonomous dog-like drones in their ongoing war with Russia.
