EditStriking Ukraine’s entry point of non-Russian gas, Moscow sends warning to West
The facility was the main entry point for reverse gas flows from Turkey and Greece, via Bulgaria and Romania
On Wednesday (6 August) Russian forces launched a targeted missile strike on the Orlivka Gas Metering Station (GMS) near Odesa – a critical hub in Ukraine’s energy infrastructure. Ilian Vassilev commented this latest episode in the Russian aggression against Ukraine.
Ilian Vassilev is a former Bulgarian ambassador to Moscow, now a media publisher and commentator. His website Alternativata is a content partner of EUalive.
The facility was the main entry point for reverse gas flows from Turkey and Greece, via Bulgaria and Romania, through the Trans-Balkan pipeline corridor. In effect, it served as the operational backbone of the EU- and US-backed Vertical Gas Corridor which is a strategic route designed to deliver non-Russian LNG to Ukraine.
This is not just another military action. It is a calculated escalation. For years, Moscow has labelled attacks on energy infrastructure as “terrorism”. Now it has crossed its own rhetorical red lines – targeting infrastructure that carries no Russian gas and instead facilitates the very diversification of supply that the Kremlin seeks to undermine. The strike is a direct challenge to both Ukraine’s and Europe’s energy security.
Throughout the war, gas transit systems, especially those involving Russian flows, have largely remained untouched. There was a tacit understanding: Ukraine would refrain from striking Russian energy infrastructure, and Russia would not target critical Ukrainian assets as long as Russian gas continued to flow westward. Even President Erdoğan had reportedly brokered a mutual restraint pact between Kyiv and Moscow to safeguard the TurkStream pipeline.
That informal understanding ended last night.
The timing is hardly coincidental. The strike comes just days before the 8 August deadline for a decision on US aid to Ukraine, set by President Donald Trump. Washington and Brussels have invested considerable effort into clearing regulatory and logistical barriers to LNG imports via the Vertical Corridor, including strong pressure on transmission system operators to reduce tariffs and open access for non-Russian gas.
With GMS Orlivka now out of commission, the principal entry point for non-Russian gas into Ukraine has been disabled. While repairs are technically feasible, time is running out. Ukraine is currently in a critical phase of gas injection ahead of the winter heating season. Naftogaz, the state energy company, recently signed supply deals with Azerbaijan’s SOCAR and was in talks for additional LNG deliveries via terminals in Turkey and Greece aiming to inject 4-6 billion cubic metres before the first frost.
Russian propagandists openly call the strike on the Orlivka gas compressor station in Odesa region "a signal from Moscow to Aliyev."
Along this station, test volumes of Azerbaijani gas, under an agreement between Naftogaz and SOCAR, were already being delivered.

Limited alternatives, shrinking leverage
Ukraine still has access to other entry points: Veľké Kapušany (Slovakia), Beregdaróc (Hungary), Poland (via Orlen and US LNG).
However, the Trans-Balkan route – purpose-built to accommodate Azeri and other non-Russian gas, has effectively been severed. And this sends a chilling message: “You may try to diversify, but we will decide what gas flows through Southeast Europe.”
Bulgaria’s dilemma: a gateway for whom?
The strike casts a spotlight on Bulgaria’s increasingly ambiguous role in the region’s energy landscape. The country has become the EU’s sole entry point for Russian pipeline gas, allowing Moscow to retain its dominant position not only in Bulgaria but across much of Southeast Europe.
With Orlivka neutralised, the Vertical Gas Corridor has been effectively paralysed. The Trans-Balkan pipeline cannot function as a credible alternative to TurkStream without a viable Ukrainian entry point. Notably, Russia refrained from striking Veľké Kapušany or Beregdaróc – both connected to routes for Russian gas transit into Ukraine. Instead, it targeted the only route that enables reverse flows of non-Russian gas.
The message is unmistakable: “You talk of diversification, but we will determine the limits of your sovereignty.”
Despite this, the Bulgarian government continues to adopt policies that safeguard the flow of Russian gas, even in anticipation of an EU-wide ban. While other EU member states deepen their support for Ukraine, Sofia appears to be treading a different path that, intentionally or not, bolsters the Kremlin’s regional leverage.
Bulgaria enables the transit of over $8 billion worth of Russian energy products annually – revenues that directly fuel the Kremlin’s war effort. By contrast, Bulgaria’s direct aid to Ukraine remains minimal, reportedly to the point of mockery in Moscow. This calculation excludes military-industrial exports, which are treated as purely commercial transactions.
In short, Bulgaria holds the key to shutting down Russian gas access to the EU and yet continues to act as a strategic enabler, even as Russia bombs the very infrastructure meant to allow alternatives.
What’s next: risks of escalation and European paralysis
The potential consequences are serious and mounting. The destruction of Ukraine’s primary reverse-flow station brings the threat of asymmetric retaliation closer to reality. It is no longer unthinkable that Ukrainian special forces might target Russian pipelines on Russian territory, particularly those supplying gas to Bulgaria.
Russia’s strike on GMS Orlivka was not merely an attack on infrastructure. It was a direct assault on Europe’s collective energy sovereignty. The time has come for the EU, and especially for countries like Bulgaria, to act with clarity and resolve. If Moscow responds only to strength, then the age of gas diplomacy must give way to energy leverage.
