Summary
Russia has announced the commencement of systematic strikes on Kyiv, citing a May 22 drone attack in Starobelsk, Luhansk, as justification. Moscow claims the attack targeted a civilian dormitory, resulting in significant casualties, including teenagers, and has labeled Ukraine’s government as “Nazi and terrorist.” The Russian Foreign Ministry warned foreign nationals and diplomats to leave Kyiv immediately, as strikes will target defense industry facilities, decision-making centers, and command posts. This announcement follows one of the largest aerial bombardments of Ukraine to date, with hundreds of missiles and drones striking infrastructure in Kyiv and other cities. Ukraine has denied targeting civilians, while international responses from Ukraine, the European Union, and the United States have strongly condemned Russia’s actions, rejecting evacuation warnings and calling for increased military and economic support for Kyiv. Open-source intelligence indicates Russia’s military assets, including strategic bombers, hypersonic missiles, and Iskander systems, are positioned for further large-scale attacks, with Kyiv’s command and decision-making centers at high risk.
Detailed Report
1. Russian Ministry Statement: Justification, Systemic Strikes and Evacuation Warnings
1A. Starobelsk Justification and Legal Framing
The Russian Foreign Ministry attributed its escalation to a May 22 drone attack on the academic building and dormitory of Lugansk State Pedagogical University college in Starobelsk, Luhansk People’s Republic. Russian authorities reported 21 deaths and 42 injuries, with victims described as predominantly teenagers aged 14 to 18 residing in the dormitory. To learn more about this drone attack, see our earlier cable here. Moscow characterized the incident as a deliberate attack on civilians including children, labeling the Ukrainian government as “Nazi and terrorist” and describing Ukraine’s Western partners as complicit. The Ministry explicitly cited violations of the 1949 Geneva Conventions, their Additional Protocols, and the 1989 Convention on the Rights of the Child. Ukraine’s General Staff categorically denied targeting a civilian site, stating its forces struck the “Rubicon” Center for Advanced Unmanned Technologies—a military facility involved in drone operations.
1B. Announcement of Systematic Strikes
Declaring that Russia’s “patience has been exhausted,” the Ministry announced the initiation of “consistent, systematic strikes” against Ukrainian defense industry enterprises in Kyiv, specifically identifying sites used for the design, production, programming, and preparation of UAVs with NATO assistance, as well as “decision-making centres and command posts.” The statement cited the dispersal of these targets across the city as a factor in the scope of planned strikes.
1C. Evacuation Warning
The Ministry’s official warning stated: “We warn foreign nationals, including staff of diplomatic missions and representative offices of international organisations, of the need to leave the city as soon as possible, urge residents of the Ukrainian capital not to approach the military and administrative infrastructure facilities of the Zelensky regime.” Foreign Minister Sergey Lavrov personally conveyed this warning to U.S. Secretary of State Marco Rubio by telephone on May 25, advising that the United States and other states with missions in Kyiv ensure the evacuation of their diplomatic personnel and citizens. Rubio confirmed receipt of the warning and stated he relayed Lavrov’s message to U.S. President Donald Trump.
2. Context: Previous Russian Strikes on Kyiv, May 23–24, 2026
Between May 23 and 24, Russian forces launched approximately 600 drones and 90 missiles against Kyiv and other Ukrainian cities, representing one of the most intense aerial bombardments since the start of the full-scale invasion. According to Ukrainian Air Force data, air defenses intercepted 549 drones and 55 missiles; however, at least four people were killed and more than 80 injured in Kyiv alone.

3. International Responses
3A. Ukraine
· Ukrainian Foreign Minister Andrii Sybiha stated:
“Russia has launched yet another massive missile and drone attack against Ukraine this night, using at least 650 drones and missiles and deliberately targeting civilians. This is not warfare – it is a calculated campaign of terror against our people. Russia’s leadership must be held fully accountable for these war crimes. There is nothing accidental about these strikes – they are ordered, planned, and executed with full awareness of their civilian toll. Those responsible will be brought to justice. The only adequate response to Russian terror is maximum pressure, strengthened sanctions, and expanded support for Ukraine to stop this aggression and restore security in Europe.” (MFA Ukraine, May 26, 2026)
Sybiha further called on Ukraine’s partners to deliver additional air defense systems and missiles, accelerate Ukraine’s EU accession, and dismissed Russian peace signals as manipulative.
3B. European Union
· EU High Representative Kaja Kallas stated via her official X account:
“Russia hit a dead-end on the battlefield, so it terrorizes Ukraine with deliberate strikes on city centres. These are abhorrent acts of terror meant to kill civilians and break Ukraine’s spirit. The EU stands united with Ukraine and will respond with stronger pressure on Russia.”
Kallas also condemned the deployment of advanced Russian missile systems, including the Oreshnik, as reckless escalation, and confirmed that EU foreign ministers would convene to discuss increasing international pressure.
· European Commission President Ursula von der Leyen stated via her official X account:
“Russia’s massive attack on Ukraine last night shows the Kremlin’s brutality and disregard for both human life and peace negotiations. Europe will continue to provide air defense support and stand by Ukraine’s side.”
· EU Mission Head Katarina Mathernova, in an official media statement, said:
“We are staying in Kyiv. We remain with Ukraine. Threatening diplomats and international organizations is not a sign of strength. It is a sign of desperation.”
3C. United States
U.S. Secretary of State Marco Rubio stated in a press briefing:
“Well, this is what happens with these wars. I mean, they just continue to escalate. There’s a big strike coming one way, the bigger strike coming back, and that’s how these things unravel and keep going. And it’s why the war needs to come to an end . . . The US stands ready and prepared to help do whatever we can to help facilitate the end of this war, and hopefully the opportunity will present itself at some point.”
4. OSINT Threat Assessment
Open-source intelligence from the X account @AMK_Mapping_, and corroborating defense sources confirm that Russia has positioned significant strike assets for further attacks on Kyiv. Recent activity includes strategic bombers such as Tu-95MS and Tu-160M stationed at Olenya, Engels-2, and Ukrainka airbases, armed with Kh-101 and Kh-555 cruise missiles. MiG-31K aircraft carrying Kinzhal hypersonic missiles have also been active at Savasleika Airbase, while Iskander-M ballistic missile systems are deployed near the Ukrainian border in Bryansk, Kursk, Voronezh, and Rostov oblasts.
Conclusion
Russia’s announcement of systematic strikes on Kyiv, coupled with evacuation warnings to diplomats and foreign nationals, marks a significant escalation in the ongoing conflict. As international condemnation mounts and military preparations on both sides intensify, the situation in Ukraine remains highly volatile, with Kyiv at the center of Russia’s stated objectives.
