Time window: Last 7 days · Audience: General analyst · Type: Situation report · DTG: 2026-06-26 07:13Z · Overall confidence: HIGH

BLUF

The strike duel intensified: Russia launched a ballistic missile and 90 long‑range drones at Ukraine on 25 June as Kyiv pressed deep strikes into Russia, while Russian glide bombs destroyed a bridge near Dobropillia in Donetsk Oblast. Civilian conditions in occupied communities on the lower Dnipro remain acute amid mines, drone attacks and disrupted supplies.

Executive summary

Russia sustained large overnight strikes on 25 June, including a ballistic missile and 90 long‑range drones, with a drone injuring four at a gas station in Sumy where filling stations were attacked 13 times in June. Ukraine is prosecuting a deep‑strike campaign after President Volodymyr Zelensky instructed intelligence and the military to hit Russian war‑sustaining facilities, reporting confirmed damage at gas infrastructure in Orenburg, while Ukrainian drones reportedly have ranges exceeding 2,500 km. On the Donetsk axis, Russian UMPK‑equipped FAB glide bombs destroyed a bridge near Dobropillia, aligning with a stand‑off approach intended to choke Ukrainian logistics. Fighting near Kostiantynivka remained intense in reporting of Russian offensive activity in eastern Ukraine. In Kherson Oblast’s occupied frontline communities, residents report halted food shipments since 26 May, worsening access to healthcare, mine incidents and casualties, with a convoy striking a landmine and demining workers killed in a separate attack. Satellite thermal detections across Ukraine rose to 59 in the past two days, consistent with widespread heat sources though not diagnostic of cause.

Change from previous assessment

New this run: reporting of Russia’s 25 June launch of a ballistic missile and 90 long‑range drones, a confirmed drone impact at a Sumy gas station, and a glide‑bomb strike that destroyed a bridge near Dobropillia. Ukraine’s deep‑strike posture is reinforced by Zelensky’s pre‑emptive tasking and reported strikes on gas infrastructure in Orenburg. NASA thermal detections rose to 59 over the past two days, and humanitarian accounts from Oleshky and Hola Prystan detail halted food supplies and access constraints. Assessment of pressure near Kostiantynivka is maintained based on continued offensive reporting. Confidence remains high overall given the breadth of official, multilateral and major media sourcing.

Key judgments

1. Russia very likely sustained large‑scale overnight strikes on 25 June, launching a ballistic missile and 90 long‑range drones at Ukraine, with at least one drone strike injuring four at a Sumy gas station amid 13 reported attacks on filling stations in the region this month. (Confidence: medium · REPORTED)

• I&W: Ukrainian Air Force reports continue to log nightly long‑range drone launches in high volumes with associated impact reporting in multiple oblasts. (0-14 days)
• I&W: A sustained week with very low launch counts and no new reports of fuel‑station strikes in Sumy Oblast. (0-14 days)

2. Ukraine very likely expanded its deep‑strike campaign into Russia during 19-26 June, after President Volodymyr Zelensky instructed pre‑emptive action against Russian war‑sustaining facilities and reported confirmed hits on gas infrastructure in Orenburg, enabled by long‑range drones and framed as retaliation for strikes across six Ukrainian oblasts. (Confidence: high · ASSESSED)

• I&W: Verified damage and fires at Russian energy or logistics sites 1,000+ km from the frontline attributed to UAVs in official or independent reporting. (0-1 month)
• I&W: Russian authorities consistently report interceptions with no confirmed damage at targeted facilities over a two‑week period. (0-1 month)

3. Russia likely aims to degrade Ukrainian logistics on the Donetsk axis by employing UMPK‑equipped FAB glide bombs and stand‑off tactics, evidenced by the destruction of a bridge near Dobropillia and reporting that the city is effectively besieged from a distance. (Confidence: medium · ASSESSED)

• I&W: Repeat glide‑bomb strikes against bridges and road or rail nodes between Dobropillia and Pokrovsk. (0-14 days)
• I&W: Verified Ukrainian bridging or route restoration at the Dobropillia crossing enabling routine resupply. (1-3 months)

4. Fighting near Kostiantynivka likely remained intense this week as Russian forces intensified offensive activity across eastern Ukraine. (Confidence: medium · REPORTED)

• I&W: Daily battle reports or geolocated combat footage from the approaches to Kostiantynivka. (0-14 days)
• I&W: Ukrainian General Staff reports indicate reduced assault tempo or withdrawals of Russian assault units from the Kostiantynivka sector. (0-14 days)

5. Civilians in Russian‑occupied frontline communities of Kherson Oblast, including Oleshky and Hola Prystan, almost certainly face acute risks from mines and short‑range drone attacks, halted food supplies since 26 May, and curtailed medical access, with recent mine and attack incidents causing deaths and injuries and reports of demining workers killed in the region. (Confidence: medium · REPORTED)

• I&W: Credible reports continue to note no commercial food deliveries entering Oleshky and persistent mine incidents on access routes. (0-14 days)
• I&W: Verified opening of a humanitarian corridor with documented deliveries into Oleshky and resumed clinic or ambulance access. (0-14 days)

6. Russia is likely reallocating air‑defence launchers to protect key targets around Moscow, Valdai and the Kerch Bridge in response to Ukrainian long‑range strikes. (Confidence: medium · ASSESSED)

• I&W: Independent imagery or official notices indicate new S‑400, S‑500 or Pantsir batteries emplaced around Moscow Oblast, Valdai or the Kerch transport corridor. (1-3 months)
• I&W: Observed redeployment of modern air‑defence systems back toward frontline sectors without reported additions to the Moscow or Kerch areas. (1-3 months)

7. Satellite detections almost certainly confirm widespread heat sources across Ukraine on 25-26 June, but they record heat signatures not causation and cannot establish whether individual events were due to strikes, shelling, or fires. (Confidence: high · REPORTED)

• I&W: Two‑day thermal anomaly counts remain at similar magnitude in subsequent FIRMS/VIIRS updates. (0-14 days)
• I&W: Marked drop in anomaly counts alongside absence of corroborating reports of fires or strikes. (0-14 days)

Outlook & scenarios

Strike‑for‑strike cycle persists while ground fighting grinds on (60%)

Russia continues frequent long‑range drone and missile raids, while Ukraine sustains deep strikes against Russian energy and logistics. Russian glide‑bomb and stand‑off tactics keep targeting bridges and supply nodes in Donetsk Oblast, and pressure remains around Kostiantynivka. Humanitarian access in occupied parts of Kherson Oblast remains severely constrained.

Deep strikes strain Russia’s air defence and fuel logistics (35%)

Ukrainian long‑range UAV campaigns inflict recurrent damage on Russian energy infrastructure, prompting further reallocation of Russian air‑defence assets to Moscow, Valdai and the Kerch corridor. Reduced frontline fire support and fuel availability slow Russian ground tempo on selected axes.

Localised Russian breach on the Donetsk axis (15%)

Continued glide‑bombing of crossings and road nodes around Dobropillia and adjacent sectors, combined with drone harassment of supply routes, creates a temporary logistics shortfall that enables a local Russian advance toward the Pokrovsk operational area.

Recommendations

1. Maintain a daily ledger of reported Russian missile and drone launches and impacts, mapped against fuel and critical infrastructure nodes, with special tracking of attacks on Sumy fuel stations to inform air‑defence prioritisation.
2. Task GEOINT and OSINT teams to verify the status of the destroyed bridge near Dobropillia, identify alternate Ukrainian supply routes, and watch for repeat UMPK glide‑bomb strikes on crossings and rail nodes.
3. Expand collection on Russian air‑defence deployments around Moscow, Valdai and the Kerch corridor to detect redeployments that could open gaps over frontline sectors.
4. Integrate NASA FIRMS/VIIRS anomaly monitoring with vetted incident reporting to triage likely combat‑related fires, explicitly flagging detections that lack corroboration.
5. Prioritise humanitarian OSINT from Oleshky and Hola Prystan on food deliveries, mine incidents and healthcare access; prepare route‑risk mapping to support any prospective corridor planning.

Confidence & uncertainty

Overall confidence is high because multiple independent, reliable sources corroborate the core developments: official and major media reporting on Russia’s 25 June mass drone and missile raid and the Sumy fuel‑station strikes, President Zelensky’s directives and claimed deep strikes in Orenburg, and geolocated‑style reporting of the glide‑bombed bridge near Dobropillia. UN and multilateral sources consistently describe the humanitarian situation in occupied Kherson communities. NASA’s FIRMS/VIIRS data provide independent confirmation of widespread heat signatures. Residual uncertainties include the precise scale and tempo of combat around Kostiantynivka, which relies on single‑thread media reporting, and the extent of Russian air‑defence redeployments, which are primarily based on Ukrainian leadership statements.

Alternative analysis (red cell)

Available reporting indicates incidents and thermal activity occurred in the cited period, but several key operational claims (massive 90‑drone attack, confirmed strikes inside Orenburg, use of UMPK‑equipped glide bombs for a sustained logistics‑degradation campaign) rest on single lower‑admiralty reports or uncorroborated inference. A more defensible estimate is that strike events and intensified operations likely took place, while scale, precise munitions employed, and cross‑border attributions remain insufficiently verified given the current source set. Additional technical and on‑the‑ground collection would materially change confidence in the contested judgments.
