Russia Resumes Heavy Strikes on Ukraine After Ceasefire Ends
Hostilities escalated sharply after a three-day ceasefire in Ukraine ended early on 12 May, with reports of heavy shelling, KAB glide-bomb strikes, and renewed Geran-2 drone launches. Significant damage and civilian casualties were reported in Kyiv, Dnipro, Kherson and other regions following overnight attacks starting before 04:30 UTC.
Key Takeaways
- A three-day ceasefire in Ukraine expired, and Russia quickly resumed large-scale strikes with artillery, glide bombs, and drones on 12 May.
- Overnight and into the morning, attacks hit Kyiv, Dnipro, Kherson and other regions, damaging residential buildings and a kindergarten and injuring multiple civilians.
- Ukrainian sources report heavy use of Geran-2 drones and KAB glide-bombs, with preparations for a larger combined missile-drone strike noted 5–6 days earlier.
- The renewed intensity underscores the fragility of ad hoc pauses in fighting and foreshadows further large-scale aerial attacks.
In the early hours of 12 May 2026, shortly after the end of a three-day ceasefire, Russia resumed high-intensity military operations against Ukraine. By around 04:30 UTC, Ukrainian officials and local authorities were reporting widespread drone and missile activity over multiple regions, including the capital Kyiv, the central city of Dnipro, and the southern Kherson region. The renewed strikes marked a rapid reversal from the relative calm of the ceasefire period.
Reports indicate that Russian forces launched waves of Geran-2 loitering munitions and conducted airstrikes using KAB-series glide bombs, alongside heavy artillery and rocket fire on frontline positions. Monitoring sources noted that preparations for a large combined missile and drone attack had been observed five to six days earlier, suggesting that Russian planners used the ceasefire window to stage assets and refine targeting.
In Kyiv, drone debris reportedly struck a 16-story residential building, causing a substantial fire. In the surrounding region, a kindergarten sustained damage from the attacks. In Dnipro, at least one civilian was reported injured, and transport infrastructure was damaged, affecting mobility and logistics in the city. In Kherson, a 68-year-old woman was wounded during shelling. Other regions also reported strikes, including damage to energy and transport infrastructure, although full casualty and damage tallies remain fluid.
Key actors in this renewed escalation include the Russian Aerospace Forces, which are responsible for deploying KAB glide bombs and coordinating aerial strike packages, and Russian units operating Geran-2 drones from multiple launch sites. On the Ukrainian side, national air defense forces and regional authorities are again under pressure to intercept incoming threats, manage emergency responses, and restore critical services following the overnight bombardments.
This reintensification of fighting matters for several reasons. First, it underscores the limited durability and scope of ceasefire arrangements not rooted in more comprehensive political agreements. The rapid transition from pause to high-intensity attacks suggests that both sides used the lull primarily for force reconstitution, logistics, and redeployment, rather than as a step toward de-escalation.
Second, the targeting of civilian infrastructure—including residential buildings, educational facilities, and transport nodes—reinforces patterns observed throughout the war. Such strikes complicate humanitarian operations, drive additional internal displacement, and increase pressure on Ukraine’s emergency services. They also deepen public trauma and harden political positions, making future negotiations more challenging.
Third, the use of KAB glide bombs and Geran-2 drones highlights ongoing Russian efforts to combine massed, relatively low-cost unmanned systems with more precise, heavy munitions to saturate Ukrainian air defenses. For Ukraine, this demands continual adaptation of air defense tactics, including better early warning, layered interception capability, and improved protection for key urban centers.
Regionally, the renewed attacks heighten security concerns across Eastern Europe, particularly in neighboring NATO states that fear spillover effects from debris, misfires, or cyber and electronic warfare components of such strikes. The intensity and scope of the post-ceasefire operations will factor into allied debates about further air defense support and long-range strike capabilities for Kyiv.
Outlook & Way Forward
In the short term, additional large-scale aerial attacks are likely, especially if Russian planners seek to exploit perceived gaps in Ukrainian defenses or to signal resolve after the ceasefire. Analysts should expect further use of Geran-2 drones in saturation roles, potentially combined with cruise and ballistic missiles aimed at power, transport, and industrial nodes.
Ukraine will likely respond by pushing for expanded and accelerated air defense assistance, including systems with better capabilities against glide bombs and low-flying drones. The renewed civilian toll will also strengthen Kyiv’s diplomatic case for increased sanctions on Russian defense-industrial sectors and for additional long-range strike permissions from Western partners.
Strategically, unless paired with a broader negotiation framework, short-duration ceasefires are unlikely to produce lasting de-escalation. The pattern seen on 12 May—operational pause followed by rapid escalation—could become a template for future cycles. Observers should monitor whether subsequent pauses are used predominantly for humanitarian relief or primarily for military repositioning, which will reveal intentions on both sides and shape prospects for any substantive peace process.
