Overview
- Ukraine's Security Service said it struck an FSB coordination centre in Russian-held Kherson on May 22, destroying a Pantsir air-defence system and claiming roughly 100 Russian casualties.
- Russia says Ukrainian drones hit a student dormitory in Starobilsk and has reported dozens of dead and injured, while Kyiv rejects that account and says it targeted a Russian drone command post (Rubikon); independent verification is limited.
- Overnight on May 24 Russian forces launched a large missile-and-drone barrage against Kyiv and nearby areas, with Ukrainian and monitoring groups reporting more than 50 missiles and hundreds of drones, multiple deaths, dozens injured and widespread infrastructure damage.
- The U.S. Embassy in Kyiv warned of a likely large-scale Russian air attack within 24 hours and national air alerts were issued, and President Putin ordered the Defence Ministry to prepare proposals for retaliation.
- Analysts say Ukraine's growing long-range strike ability—after degrading many Pantsir systems—has extended battlefield reach, but restricted access to occupied zones and competing official narratives leave casualty and target claims contested and heighten diplomatic and escalation risks.
