A Russian terror attack on 17 June was the largest of the full-scale war, says military expert Ivan Kyrychevskyi. Russia deliberately targeted residential buildings with missiles with cluster munitions to kill as many civilians as possible, Espreso reports. 

“Before 17 June, the maximum was 200–300 aerial weapons launched at once. This time, the Russians used nearly 500, most of them kamikaze drones,” Kyrychevskyi explains.

The UN has also noted that this attack on Kyiv may be the deadliest in nearly a year. The main impact hit densely populated neighborhoods, not military targets.

“X-101 missiles with cluster warheads can’t break through fortifications, but they kill people. That’s why they were used deliberately against civilians,” Kyrychevskyi says.

No one believes anymore that the strikes on Ukrainian hospitals and children’s centers are a “mistake.” After the attack on Kyiv’s Ohmatdyt children’s hospital in 2024, Western governments have stopped buying into the narrative of “accidental strikes,” adds the expert. 

Russia began its full-scale terror campaign against the Ukrainian civilian population in 2022, burning 90% of Mariupol and Bakhmut and committing atrocities during the attacks on Bucha in Kyiv Oblast.

Emergency services in Kyiv have recovered fragments of cluster munitions following the overnight Russian missile and drone attack on June 17, Mayor Vitali Klitschko reported, calling it further evidence of Russia's "genocide" against Ukrainians.

"In the capital's Nyvky neighborhood, emergency workers are now finding these kinds of cluster munition parts," Klitschko said in a statement shared on social media. "Another clear sign of the genocide Russia is committing against Ukrainians."

Cluster munitions are banned under international law by more than 100 countries due to their indiscriminate nature and the long-term threat they pose to civilians, especially when unexploded submunitions remain hidden in residential areas.

While Russia and Ukraine are not signatories to the Convention on Cluster Munitions, international humanitarian organizations have repeatedly condemned the use of such weapons in populated areas. Ukraine uses cluster munitions on the battlefield against Russian forces.

The mayor's comments came hours after one of the largest and deadliest attacks on the Ukrainian capital in months, in which at least 15 people were killed and nearly 100 injured. The Russian strike, which lasted nearly nine hours, included waves of kamikaze drones, ballistic missiles, and what authorities now confirm were banned explosive parts.

President Volodymyr Zelensky called the assault "one of the most horrifying attacks on Kyiv," saying more than 440 drones and 32 missiles were launched across Ukraine overnight.

"Such attacks are pure terrorism," he said in a statement on social media. "And the whole world, the U.S., and Europe must finally respond as civilized societies respond to terrorists."

Zelensky confirmed that damage had been reported in eight districts of Kyiv, with emergency workers still searching for survivors beneath the rubble of a destroyed apartment block.

He added that strikes also hit Odesa, Zaporizhzhia, Chernihiv, Zhytomyr, Kirovohrad, Mykolaiv, and Kyiv regions. "Fifteen people are confirmed dead. My condolences to their families and loved ones," Zelensky said.

Foreign Minister Andrii Sybiha also condemned the attack, calling it a "massive and brutal strike" timed deliberately to coincide with the G7 summit, which is taking place in Canada on June 16-17.

On 3 June mining, Russia continued deadly attacks on Ukrainian territory, striking central Sumy city with a long-range rocket system, equipped with cluster warheads, and launching a Kinzhal aeroballistic missile that landed outside Mykolaiv, according to local authorities and airspace monitoring sources. The Sumy attack killed at least two civilians.

Sumy: Russian cluster rocket attack kills civilians, injures children

At approximately 09:18, multiple explosions were reported in central Sumy. According to the Sumy Oblast Military Administration, Russian forces struck one of the city’s main streets, damaging vehicles.

Two civilian men were confirmed dead, and seven others injured, including children. Rescue services responded at the scene. The Sumy Oblast Prosecutor’s Office reported to public broadcaster Suspilne:

“As of 10:00, two civilians are confirmed dead and seven injured, including four children.”

Sumy City Military Administration head Serhii Kryvosheenko added that many of the wounded were being transported to medical facilities.

Ukrainian airspace monitoring Telegram channel YeRadar reported at 10:30 that Russian forces used the Tornado-S multiple launch rocket system with a cluster warhead in the attack. According to the monitoring post, “There were four impacts within the city,” at the time.

The Tornado-S is a modernized version of the Smerch (9K58), with improved accuracy and a range of up to 200 km when equipped with newer rockets. The combination with cluster munitions increases its lethality against exposed personnel, vehicles, and infrastructure.

Update

The Sumy Oblast Military Administration reported that nearly 20 people were injured in the Russian attack on Sumy, with a 17-year-old among the wounded and some victims in critical condition.

“Unfortunately, two people were killed. Our condolences go out to their families,” the administration stated.

According to preliminary data, five impacts from long-range MLRS were recorded in the city center around 09:00. The strikes damaged a medical facility, vehicles, and residential buildings, with one of the hits occurring on Remisnycha Street.

A resident told Suspilne that he had gone out to the store when his apartment was struck:

“If I had been home, I would have died.”

A day of mourning has been declared for 4 June in the Sumy community, acting city head Artem Kobzar confirmed.

Deputy director Mykola Savchenko of the regional hospital told Suspilne that 20 wounded had been admitted, five of whom were in extremely serious condition. One 40-year-old woman died in surgery. He also shared a photo of the MLRS fragments recovered from the Remisnycha Street apartment.

In another part of the city, a woman was wounded by shrapnel at the entrance to a pharmacy on Shevchenko Avenue.

Pharmacist Ruslan told Suspilne:

“The woman was in critical condition. We pulled her into the pharmacy and did everything we could. It was a severe abdominal injury. Later, we helped paramedics carry her to the ambulance. Fortunately, all our staff are safe.”

Mykolaiv: Kinzhal missile tracked from Russian MiG-31K

Ukrainian airspace monitoring channel Nikolaevsky Vanyok, linked to the military, reported at 09:51 that MiG-31K jets took off from Akhtubinsk. At 10:02, the channel stated:

“For the first time during the war, a Kinzhal has struck near us (outside the city).” 

At 10:41, the same source reported: “All is OK.”

YeRadar detailed the event further, confirming the launch from the Kamyshin area in Russia’s Volgograd Oblast and noting a projected trajectory of approximately 1,200 km westward toward central or right-bank Ukraine. The missile, an Kh-47M2 Kinzhal, is capable of maneuvering mid-flight, deviating from typical ballistic paths. It can adjust altitude and direction at hypersonic speeds due to its aerodynamic surfaces, complicating interception efforts.

The channel observed the missile traveling at approximately 7,200 km/h over the northwestern outskirts of Kyiv, heading south. It later received information about a probable impact on the outskirts of Mykolaiv. Due to the Kinzhal’s ability to adjust its path in real time, YeRadar noted it would not attempt to chart the exact route. 

Update

Monitoring channel Raketa UA noted that the Russian MiG-31K fighter jet carried out its first-ever combat sortie from the Akhtubinsk airbase on the day of the strike. Previously, such launches had only been conducted from Savasleyka airbase.

“Russia is again changing its tactics,” the channel stated, adding that this new development would make it even harder to predict potential Kinzhal launches.
