Russia Unleashes Near-1,000 Drone and Missile Barrage on Ukraine, Hitting UNESCO Site in Lviv

Smoke still curled from the blackened roof of St. Andrew’s Church in Lviv on Monday afternoon as firefighters hosed down charred beams and sifted through fallen stone. Hours earlier, a Russian drone had slammed into the 17th-century Bernardine Monastery complex in the city’s historic center, igniting a fire in a site recognized by UNESCO as part of a World Heritage property.

The strike on Lviv’s old town was one fragment of a far larger picture. From Sunday evening into late Monday, Russian forces launched nearly 1,000 drones and missiles at targets across Ukraine in one of the most intense 24-hour bombardments since the full-scale invasion began in 2022, according to the Ukrainian Air Force and independent military analysts.

Ukrainian officials said at least six people were killed and around 50 were injured nationwide as the barrages hit residential neighborhoods, medical facilities and infrastructure in at least 11 regions. The Institute for the Study of War, a Washington-based think tank that closely tracks the conflict, described the operation as the largest single strike series of the war in terms of the combined number of drones and missiles used.

Military and government officials in Kyiv said the onslaught was not an isolated escalation, but part of the opening phase of Russia’s spring–summer offensive aimed at grinding down Ukraine’s defenses and seizing more territory in the eastern Donetsk region.

A 21-hour barrage

The latest wave began on the evening of March 23, when Ukrainian radar detected swarms of Shahed-type attack drones crossing from Russia and occupied Crimea. Through the night, the Air Force said, it tracked 426 “aerial attack assets” — 392 strike drones and 34 missiles, including Kh-101 cruise missiles launched from bombers over the Caspian Sea and Iskander ballistic missiles fired from Russian territory.

By 9 a.m. on March 24, Ukrainian air defenses reported they had destroyed or disabled 390 of those targets, including 365 drones and 25 missiles, using fighter aircraft, surface-to-air missile batteries, mobile air defense teams and electronic warfare systems. Officials said seven ballistic missiles could not be intercepted, underscoring the country’s limited ability to counter such weapons without additional advanced systems like the U.S.-made Patriot.

The air raid did not end with daybreak. Between morning and early evening on March 24, Russia launched another 556 strike drones, according to the Air Force. It claimed 541 of them were shot down.

The figures could not be independently verified. Videos posted from multiple cities showed successful intercepts as well as apparent direct hits on buildings and infrastructure. Some military analysts have previously questioned Ukraine’s reported downing rates, arguing that destruction percentages consistently above 90 percent are difficult to sustain over time.

Cities once seen as safe under fire

The most symbolically charged damage came in Lviv, a city near the Polish border that had long been considered a relative haven from the worst of the war.

Lviv regional authorities said a daytime drone strike in the center injured at least 13 people and set fire to the St. Andrew’s Church and Bernardine Monastery complex, part of the Ensemble of the Historic Center of Lviv inscribed on UNESCO’s World Heritage List.

Prime Minister Yulia Svyrydenko said the attack “set fire to a 17th-century church that is part of a UNESCO World Heritage site” and damaged nearby residential blocks. “Russia is targeting not only our people and our infrastructure,” she said, “but our culture and history.”

UNESCO said in a statement it was “deeply alarmed by the attacks that hit a building in the area of the Bernardine Monastery within the World Heritage property of the Historic Centre of Lviv” and reminded all parties of their obligations under international law to protect cultural heritage during armed conflict. The agency did not explicitly name Russia as responsible, drawing criticism from some Ukrainian and European commentators.

Farther east, in the industrial city of Dnipro, a drone tore into a 14-story apartment building, leaving a jagged, blackened scar down its facade. Regional officials said between nine and 13 people were injured, among them several children, including an 18-month-old boy. Emergency crews spent hours evacuating residents from upper floors and combing through damaged apartments.

In the western Ivano-Frankivsk region, local governor Svitlana Onyshchuk said two people were killed and four wounded, including a 6-year-old child, in strikes that damaged about 10 apartment buildings and several medical facilities, among them maternity hospitals.

Other attacks and falling debris were reported in Kyiv, Odesa, Zaporizhzhia, Sumy, Vinnytsia, Mykolaiv, Chernihiv and Kharkiv oblasts, hitting energy sites, transport links and police and military facilities.

Prelude to a ground offensive

The timing and scope of the barrage fit with what Ukrainian and Western analysts describe as a broader Russian push to regain the initiative on the ground after months of attritional fighting.

In recent assessments, the Institute for the Study of War said Russian forces have likely begun their spring–summer 2026 offensive, concentrating on what Ukrainian planners call the Donetsk “Fortress Belt” — a chain of heavily defended cities including Sloviansk, Kramatorsk, Druzhkivka and Kostyantynivka.

Fierce battles are already reported around Kostyantynivka and other sectors of the eastern front. Capturing those cities would give Moscow new staging grounds for further advances and threaten key Ukrainian supply lines.

Ukrainian officials say the mass air attacks are designed to weaken those defenses indirectly: by forcing Kyiv to disperse scarce air defense assets, by degrading energy and rail infrastructure that supports front-line operations, and by increasing pressure on civilians far from the trenches.

In his evening address on March 24, President Volodymyr Zelensky said the scale and nature of the bombardment showed Russia had “no intention of really ending this war.”

“During the night, there was a massive attack — both missiles and Shaheds — and throughout the day, new waves of drones,” he said. “This is their so-called spring offensive. They are trying to break our defense and our spirit.”

Dual drone campaigns

The assault on Ukrainian cities came as Kyiv intensified its own long-range drone campaign against targets inside Russia and occupied Crimea.

The Russian Defense Ministry said its forces had shot down 389 Ukrainian drones over 13 regions and Crimea in a separate overnight incident, which would represent one of Ukraine’s largest drone operations to date. Russian officials said the drones targeted oil facilities and military sites. The claims could not be independently confirmed, but Ukrainian forces have repeatedly struck refineries, fuel depots and air bases deep inside Russia over the past year with domestically produced unmanned aircraft.

The Institute for the Study of War also reported that Ukrainian forces destroyed a launcher for Russia’s Zirkon hypersonic missile in Crimea as it was being moved into firing position on the night of March 23–24, citing Ukrainian and Russian sources. If confirmed, it would be a rare successful strike on one of Moscow’s most advanced missile systems.

Strain on defenses, shifting global focus

The latest bombardment highlighted both the resilience and the strain of Ukraine’s air defense network. While authorities trumpeted high interception rates for drones and cruise missiles, they acknowledged their inability to stop the small number of ballistic missiles launched in the same period.

Ukrainian officials have pressed Western governments for more advanced air defense systems and interceptor missiles, warning that existing stocks cannot sustain prolonged, high-intensity attacks. European governments and the United States have supplied systems such as Patriot, IRIS-T, NASAMS and SAMP/T, but deliveries have lagged behind Ukrainian requests, and inventories in donor countries are limited.

The escalation also comes at a delicate diplomatic moment. U.S.-mediated contacts between Ukrainian and Russian representatives have effectively stalled, and policymakers in Washington and European capitals are preoccupied with an expanding conflict involving Iran and its regional allies. Ukrainian diplomats have voiced concern that the war in Ukraine is slipping down the international agenda.

For residents in cities like Lviv, Dnipro and Ivano-Frankivsk, the immediate concern is more basic: whether any place in the country can still be considered a safe rear.

“This city has always been a refuge,” a Lviv resident said in a video posted on social media, standing near the smoking church. “Now even here, we wake up to drones in the sky.”

As crews boarded up shattered windows and conservation specialists assessed the damage to frescoes in St. Andrew’s Church, air-raid sirens sounded again over western Ukraine, a reminder that the record-breaking assault of March 23–24 may be less a climax than an opening move in a long, grinding campaign.
