Russian drone strikes Kyiv SBU headquarters; Slovakia summons Russian ambassador
On 4 September a Russian drone struck the central building of Ukraine's Security Service (SBU) on Volodymyrska Street in Kyiv, near the consular section of the Slovak Embassy. Slovak Foreign Minister Juraj Blanár condemned the attack and ordered the Russian ambassador in Slovakia to be summoned for explanations. Ukrainian President Volodymyr Zelensky said the drone was directed at the office of acting SBU head Oleksandr Poklad, who was not in the office at the time. A fire broke out and was later extinguished, the Consistory building of the National Preserve 'Sofia of Kyiv' was damaged, and casualties were reported.

- Slovak Foreign Minister Juraj Blanár condemned the strike and ordered the Russian ambassador in Slovakia to be summoned.
- Slovakia's consular section, located near the SBU building, was operating in limited mode; no Slovak staff were present.
- A fire broke out in the SBU building and was later extinguished; the Consistory building of the 'Sofia of Kyiv' National Preserve was damaged.
- Reported casualty figures vary: Klitschko's tally rose from 9 to 12 injured (9 hospitalized, 2 in serious condition); other reporting cites 15 injured.
- Ukrainian Foreign Minister Andriy Sybiha called the strike a serious escalation and evidence of Russia's rejection of renewed peace efforts, and urged UNESCO to step up protection of Ukraine's cultural heritage.
Why it matters
The strike hit the headquarters of Ukraine's main security service, signalling a deliberate attack on a sensitive state institution. Because the SBU building sits next to the Slovak embassy's consular section, the attack drew an EU and NATO member state directly into the diplomatic fallout, and Slovakia's summons of the Russian ambassador is a formal step against Russia over a strike on Kyiv. Ukrainian officials framed the timing — during renewed peace efforts — as evidence of Russia's rejection of diplomacy.
What happened
On the afternoon of 4 September, a Russian drone struck the central SBU building on Volodymyrska Street in Kyiv, opposite Saint Sophia Cathedral. According to President Volodymyr Zelensky, the drone was directed at the office of acting SBU head Oleksandr Poklad, who was not present at the time. A fire broke out in the building and was later extinguished; the floors and outer wall were damaged, and the Consistory building of the National Preserve 'Sofia of Kyiv', whose exterior faces Volodymyrska Street, was also damaged, while Saint Sophia Cathedral itself was not. The Zavertailo café near the cathedral was reported destroyed. Casualty figures varied across updates from Kyiv Mayor Vitaliy Klitschko — from 9 to 12 injured (9 hospitalized, 2 in serious condition) — while other reporting cited 15 injured. Aviation expert Anatoliy Khrapchynskyi suggested the jet-powered 'Shahed'-type (Geran-4) drone may have used a re-guidance mechanism to precisely hit its target, with presidential adviser Serhiy Beskrestnov pointing to possible MESH-relay online control; both said final conclusions require examination of the wreckage. Slovakia's Foreign Minister Juraj Blanár condemned the strike and ordered the Russian ambassador in Slovakia to be summoned. Ukrainian Foreign Minister Andriy Sybiha called the attack a serious escalation and evidence of Russia's rejection of renewed peace efforts, and called on international partners to condemn the attack, increase pressure on Russia, and urged UNESCO to step up protection of Ukraine's cultural heritage. Estonian Foreign Minister Margus Tsahkna also condemned the strike.
How Ukrainian sources describe it
Ukrainian sources centre the strike as a deliberate, targeted attack on the acting SBU head's office. President Zelensky and Foreign Minister Sybiha explicitly framed it as a serious escalation and as evidence that Moscow is rejecting renewed peace efforts. Ukrainian reporting emphasises collateral damage to cultural heritage — the Consistory building of the 'Sofia of Kyiv' National Preserve and the Zavertailo café — and Sybiha's call for UNESCO involvement. Technical coverage foregrounds analysis by aviation expert Anatoliy Khrapchynskyi and presidential adviser Serhiy Beskrestnov on possible re-guidance or MESH-relay control mechanisms used by the jet-powered Shahed/Geran-4 drone, with both noting that final conclusions require examination of the wreckage.
Where reporting differs
Reported casualty figures vary across sources and over time: Mayor Klitschko initially reported 9 injured and later updated the count to 12 (9 hospitalized, 2 in serious condition), while other reporting cited 15 injured in total. Russian public channels claimed the strike was staged using a 'small drone,' a claim Ukrainian presidential adviser Beskrestnov publicly disputed.
Background
The SBU, the Security Service of Ukraine, is Ukraine's domestic security and intelligence agency; its central building stands on Volodymyrska Street opposite Saint Sophia Cathedral, a UNESCO World Heritage site. Slovakia's consular section adjacent to the SBU building had already been operating in a limited mode for security reasons prior to the strike, and no Slovak staff were present at the time of the attack.
