On Thursday, 26 December 2025, Ukrainian forces said they used British Storm Shadow cruise missiles to strike the Novoshakhtinsk oil refinery inside Russia, producing multiple explosions at the site. Kyiv’s general staff said the plant is a major supplier of petrol products in southern Russia and directly supports Russian military logistics. President Volodymyr Zelenskyy separately reported productive talks with envoys from former US president Donald Trump on possible peace formats. The day also saw a Russian court hand a six year sentence to opposition figure Sergei Udaltsov and Kremlin comments on the case of detained French scholar Laurent Vinatier.
Key takeaways
- Ukraine reports it struck Novoshakhtinsk refinery in Rostov region on 26 December 2025 using British-supplied Storm Shadow missiles; Ukrainian general staff noted numerous explosions at the site.
- The Novoshakhtinsk plant was described by Kyiv as a key supplier of petrol products for southern Russia and as being involved in fuel supply to Russian armed forces.
- President Zelenskyy said he had “very good” talks with envoys Steve Witkoff and Jared Kushner about peace proposals and timelines, following limited concessions in a US-led draft plan under Moscow review.
- Russian court sentenced Sergei Udaltsov to six years for allegedly justifying terrorism; Udaltsov denies the charges and has declared a hunger strike, according to independent media.
- The Kremlin said it made an offer to France regarding Laurent Vinatier, a French political scholar serving a three year sentence, and said further steps are now for France to consider.
- Mariupol’s Drama Theatre, destroyed in a 2022 strike that killed civilians sheltering inside, is being rebuilt and scheduled to reopen by month end; former company members condemned the reopening as disrespectful to victims.
Background
The Russia-Ukraine conflict has included cross-border strikes and strikes on logistics infrastructure for both sides. Since the UK supplied Storm Shadow missiles to Kyiv, Ukrainian forces have acknowledged using them for precision strikes on targets inside Russia that they say support the Kremlin’s war effort. The missiles’ long range and accuracy have altered Kyiv’s operational options for reaching deeper logistical nodes.
The Novoshakhtinsk refinery sits in Russia’s Rostov region, an area long linked to fuel provision for southern military formations. Disrupting refinery operations can degrade fuel availability for vehicles and generators, complicating supply chains that are already strained by international sanctions and battlefield attrition.
Diplomatically, Kyiv continues to press for international support for both defensive needs and a negotiated settlement. The US-led draft peace framework under discussion has prompted limited concessions reported by Kyiv, but Moscow’s response remains cautious, keeping a negotiated outcome uncertain in the near term.
Main event
Ukrainian military authorities issued a statement on 26 December saying they struck the Novoshakhtinsk refinery with Storm Shadow cruise missiles, adding that observers recorded multiple explosions at the facility. Kyiv characterized the plant as a major fuel supplier for southern Russia and linked it directly to supplying the Russian armed forces.
The use of British-supplied Storm Shadow missiles marks a continuation of Kyiv’s declared policy to target logistical infrastructure that it identifies as supporting Russia’s military operations. British authorities previously approved delivery of these long-range cruise missiles to Ukraine, citing the need to help Kyiv disrupt supply lines while trying to manage escalation risks.
Hours after Kyiv’s announcement, President Zelenskyy posted on Telegram that talks with envoys associated with former US president Donald Trump were “very good,” highlighting new ideas on formats, meetings and timelines intended to advance a path to peace. Zelenskyy said the discussions included details and proposals that could bring “real peace closer.”
In Moscow, a court convicted opposition activist Sergei Udaltsov of justifying terrorism and sentenced him to six years in prison. Independent outlets reported Udaltsov’s arrest occurred last year and that he denies the charges, calling them fabricated; he has announced a hunger strike in protest of the verdict.
The Kremlin told reporters it had presented an offer to France concerning Laurent Vinatier, the French scholar serving a three year sentence in Russia for collecting military information, and said the ball is now in France’s court. French authorities said they were closely following the case and providing consular support.
Analysis & implications
A strike on Novoshakhtinsk has immediate tactical implications: damaging refinery output reduces refined fuel exports and internal supplies, potentially constraining Russian operations that depend on steady fuel deliveries. Even temporary outages can ripple through front-line logistics, transport and air operations that rely on road and rail fuel movements.
The political implications are more complex. Kyiv’s use of Western-supplied long-range weapons inside Russian territory risks raising tensions with donor states, which weigh the military advantage against escalation concerns. So far, the UK has defended the transfer of Storm Shadow missiles as strictly for legitimate military targets; Kyiv frames strikes as aimed at degrading the Kremlin’s ability to prosecute the war.
Diplomatically, Zelenskyy’s reported engagement with envoys linked to the former US administration suggests Kyiv is exploring multiple channels to press for a settlement. While Kyiv says it won limited concessions in a revised US-led draft, the involvement of additional intermediaries could influence timelines and formats — but any breakthrough requires Moscow’s substantive response.
The Mariupol theatre reopening underscores a different front in the conflict: governance and narrative control in occupied areas. Moscow showcases reconstruction as normalisation, while critics and displaced Ukrainians see the moves as attempts to legitimize occupation and erase wartime grievances, complicating future reconciliation or return processes.
Comparison & data

The specifications above explain why the system enables strikes on deep logistics nodes such as Novoshakhtinsk from Ukrainian-controlled territory. Precise, air-launched or ground-launched variants allow Kyiv to engage hardened and dispersed targets while reducing risk to aircraft and crews.
Reactions & quotes
There were many useful and constructive ideas; we discussed formats, meetings and a timeline that could bring real peace closer.
Volodymyr Zelenskyy, President of Ukraine (Telegram)
The comment followed Zelenskyy’s statement that Kyiv had secured limited concessions in a US-led draft peace plan. His office framed the talks as part of broader diplomatic efforts to move toward negotiations.
We have made an offer to the French and now the ball is in France’s court; I cannot disclose the details.
Dmitry Peskov, Kremlin spokesperson (press briefing)
Peskov’s remark referred to discussions over Laurent Vinatier, whose case Paris says it is following closely; Moscow did not publish specifics on the purported offer.
The verdict is shameful; I will not recognise this fabricated charge and will begin a hunger strike.
Sergei Udaltsov, opposition activist (statement via independent media)
Udaltsov’s response came after his conviction for allegedly justifying terrorism; independent outlets reported his rejection of the charges and his planned protest action.
Unconfirmed
- Independent verification of the full extent of damage at Novoshakhtinsk and its immediate impact on local fuel distribution is pending open-source confirmation and satellite imagery analysis.
- The precise contents of the Kremlin’s “offer” to France about Laurent Vinatier have not been publicly disclosed and remain unverified.
- Reports of internal Russian logistics disruptions directly attributable to this single strike have not yet been corroborated by independent observers.
Bottom line
Kyiv’s strike on the Novoshakhtinsk refinery, as described by Ukrainian authorities, represents a tactical effort to degrade fuel supplies that support Russian military operations in the south. The use of British-supplied Storm Shadow missiles highlights how Western long-range capabilities are reshaping Kyiv’s operational reach and target set.
At the same time, diplomatic signals this week — from Zelenskyy’s talks with envoys and the US-led draft peace plan to Kremlin-French exchanges over a detained scholar — show that military and political tracks remain active and intertwined. Independent verification of damage and longer-term effects on Russian logistics will be critical to assessing whether this strike shifts battlefield dynamics or primarily serves as leverage in broader negotiations.
