On the night of 23-24 May 2026, a massive combined strike targeted Kyiv and its region. The offensive involved roughly 600 drones and 90 missiles, including an intermediate-range Oreshnik ballistic missile with hypersonic capabilities. It caused civilian casualties and damaged residential, cultural and educational infrastructure. Over the same period, strikes also hit Russian territory, in the Belgorod and Vladimir regions.
The use of the Oreshnik against the Ukrainian capital was one of its first deployments on that target, and the third since November 2024. The weapon is described as covering a large part of Europe and as difficult to intercept with current defenses, making it a marker in the escalating range of means used since the conflict began.
The episode fits into a sustained intensification of long-range strike exchanges between the two sides, with no formal negotiations under way. On the diplomatic front, the period was marked by a request for an emergency UN Security Council meeting, a phone call between Paris and Minsk, and condemnations from several European capitals. The spread of drone warfare into the airspace of NATO member states, such as Latvia and Lithuania, has also fueled debate over the Alliance's obligations.
The meaning of the event remains disputed. Moscow presents the offensive as announced and proportionate retaliation, following an attack attributed to Ukraine on a student dormitory in Starobilsk. Kyiv rejects that justification and calls the strike a deliberate escalation. Other actors take a more technical view, stressing the missile's characteristics and the reciprocity of cross-border strikes. With no independent investigation available, several casualty figures and responsibilities remain unverifiable.
