Turkey, Russia & the Black Sea
Assessment
Turkey is running its long balancing act between Ukraine and Russia under sharper Black Sea pressure. Foreign Minister Hakan Fidan used the 8 June Istanbul trilateral with Azerbaijan and Georgia to call peace in the Russia–Ukraine war 'essential for regional stability' and to warn of deteriorating Black Sea maritime security as the conflict spreads to civilian shipping — a warning the war made literal: on 28–29 May a Russian drone struck the Turkish-owned cargo ship ANT sailing from Odesa, injuring two Turkish crew and starting a fire, while the day before Ukrainian sea drones hit three Russian shadow-fleet tankers (James II, Altura, Velora) off Turkey's northern coast. Ankara condemned the ANT strike and pressed for restraint, but it does not join Western sanctions, keeps Russian energy flowing (TurkStream is now the sole pipeline route for Russian gas to Europe; Rosatom's $20bn-plus Akkuyu plant nears Unit 1 startup), and Turkish soil is named in a German bust of a €30m dual-use sanctions-evasion network feeding Russia's military. As mediator and gatekeeper of the straits, Turkey keeps a foot in both camps — backing Crimean Tatar rights and the war's victims while refusing to break with Moscow — and Zelensky's pre-winter diplomatic framework explicitly lists Turkey alongside the E3 and Nordics. By June 2026 the open question is whether Black Sea incidents force Ankara off the fence, or whether the cost of choosing keeps it balancing.

- 1 8 Jun 2026 Fidan calls Ukraine peace 'essential,' warns of Black Sea security deteriorationIstanbul
At the 10th Trilateral Meeting of Türkiye, Azerbaijan and Georgia in Istanbul on 8 June 2026, Foreign Minister Hakan Fidan said achieving peace in the Russia–Ukraine war is essential for regional stability, voiced concern over the battlefield and diplomatic deadlock, and warned that Black Sea maritime security is deteriorating as the conflict expands. He urged ceasefire negotiations and stressed the strategic value of regional cooperation, while also supporting the Azerbaijan–Armenia peace process. The warning came days after a Russian drone hit a Turkish-owned cargo ship leaving Odesa and Ukrainian drones struck Russian tankers off Turkey's coast.
Mediator framingFidan casting Ukraine peace as 'essential for regional stability' rather than taking a side keeps Turkey in the mediator's chair it has occupied since the 2022 Istanbul grain deal — advocating a ceasefire without committing to sanctions or recognition, the posture that lets Ankara talk to both Moscow and Kyiv.Black Sea as the new frontNaming deteriorating Black Sea maritime security as the specific worry ties the diplomatic appeal to two concrete incidents in the prior fortnight — the ANT cargo-ship strike and the sea-drone attacks on shadow-fleet tankers — turning an abstract peace call into a defence of the shipping lanes Turkey's economy and straits authority depend on.Venue choiceDelivering it at a Türkiye–Azerbaijan–Georgia trilateral, not a NATO or EU platform, signals Ankara organising Black Sea security through its own regional bloc — a frame that excludes Russia but also keeps the initiative under Turkish, not Western-alliance, leadership. - 3 Jun 2026 Turkey launches Sea Wolf-2/2026 naval exercise across the Black Sea and three other seasBlack Sea / Marmara / Aegean / E. Mediterranean
On 4 June 2026 the Turkish Naval Forces Command began the Sea Wolf-2/2026 exercise spanning the Black Sea, Sea of Marmara, Aegean and Eastern Mediterranean, involving 125 naval assets, 60 aircraft and 18,000 personnel. The drill featured live-fire of domestically developed systems including ATMACA anti-ship missiles, AKYA heavyweight torpedoes and HISAR-D naval air-defence missiles, plus the first operational use of the PIRANA kamikaze unmanned surface vessel. The exercise aimed to test command and control, combat readiness and interoperability days after Russian and Ukrainian strikes hit shipping in Turkey's maritime neighbourhood.
Demonstrating Black Sea controlRunning a four-seas live-fire exercise with 125 platforms immediately after the ANT and shadow-fleet strikes is Ankara physically asserting that it, not Russia or Ukraine, sets the security tempo in the Black Sea — a hard-power counterpart to Fidan's diplomatic warnings the same week.Indigenous kill chainDebuting the PIRANA kamikaze USV alongside ATMACA missiles shows Turkey fielding the same unmanned-surface-vessel class Ukraine just used against Russian tankers — evidence Ankara is building an autonomous Black Sea strike capability that reduces its dependence on any outside supplier, Russian or Western.Capability under MontreuxThe drill is conducted by Turkey's own navy inside waters it controls under Montreux, where non-littoral warships are capped — underscoring that in the Black Sea the dominant deployable force is Turkish, the structural fact behind Ankara's claim to be the region's indispensable security actor. - 1 Jun 2026 Zelensky's pre-winter diplomatic framework lists Turkey alongside the E3 and NordicsUkraine (E3 + Nordics + Turkey format)
On 1 June 2026 President Zelensky said Russia has been losing battlefield initiative since late 2025, creating a limited diplomatic window before winter, and proposed a negotiation framework involving the UK, France, Germany, the Nordic countries and Turkey, conditioned on increased pressure on Moscow including expanded sanctions. Presidential Office chief Kyrylo Budanov said Zelensky had instructed officials to seek an end to the active phase of the war before winter, citing 'real signs' that conditions exist, while Berlin prepared an E3-led negotiation format.
Turkey inside the formatZelensky naming Turkey alongside the E3 and Nordics in his negotiation framework formally invites Ankara into the mediator group — demand-side recognition that Turkey's straits control and channels to Moscow make it useful at the table even though it sanctions no one.Pressure premised on sanctions Turkey won't applyThe framework's precondition is 'expanded sanctions,' a lever Turkey explicitly declines to pull — exposing the tension in including a member whose value is its openness to Russia while the strategy depends on closing Russia off, a contradiction Kyiv accepts for access.The winter clockBudanov's 'before winter' deadline gives the diplomacy a hard timeline, the same seasonal pressure behind Fidan's June ceasefire appeals — both Kyiv and Ankara reading the slowing Russian offensive as a closing window, aligning their tempo even as their sanctions positions diverge. - 2 29 May 2026 pivotal Russian drone strikes Turkish-owned cargo ship ANT leaving Odesa, injuring two crewBlack Sea (off Odesa)
On 28–29 May 2026 a Russian drone struck the Turkish-owned, Vanuatu-flagged cargo vessel ANT as it sailed from Odesa, Ukraine, toward Turkey, injuring two Turkish crew members and starting a fire aboard. Turkey's Foreign Ministry condemned the attack, called for restraint, and reiterated the need to ensure the safety of civilian shipping in the Black Sea. The strike directly hit Turkish nationals and Turkish-owned tonnage on a commercial route, escalating the war's reach into the civilian maritime trade Ankara has positioned itself to protect.
Turkish casualtiesTwo injured Turkish crew on Turkish-owned tonnage is the first time in this timeline the war drew Turkish blood at sea — a qualitative shift from Turkey watching the Black Sea war to being a victim of it, the exact scenario Fidan's 8 June 'civilian shipping safety' warning was built around.Odesa-to-Turkey routeThe ANT was on the Odesa–Turkey grain-and-cargo lane that Turkey's 2022 Black Sea Grain Initiative was designed to keep open; a Russian strike on that corridor undercuts the very trade infrastructure Ankara brokered, giving Turkey a direct commercial grievance against Moscow rather than a diplomatic one.Condemnation without ruptureTurkey 'condemned' the strike and 'called for restraint' — deliberately symmetric language that names no sanction and demands no Russian accountability, the measured response of a state that will protest an attack on its citizens but not let it break the energy and Akkuyu ties to Moscow. - 28 May 2026 pivotal Ukrainian sea drones strike three Russian shadow-fleet tankers off Turkey's coastBlack Sea (off northern Turkey)
On 28 May 2026 Ukrainian sea drones struck three tankers linked to Russia's shadow fleet — the Palau-flagged James II and the Sierra Leone-flagged Altura and Velora — in the Black Sea near Turkey's northern coast, hitting them while sailing in ballast or conducting ship-to-ship transfers. No casualties were reported; all three vessels had been previously sanctioned for transporting Russian oil. Ukraine's military intelligence (HUR) said the shadow fleet accounts for up to 30% of Russia's seaborne oil exports, framing the attack as a strike on Moscow's war financing.
Strike zone near Turkish watersUkraine pushing sea-drone strikes to within reach of Turkey's northern coast extends the maritime war into the approaches Ankara polices under Montreux — a Ukrainian operation against Russian targets unfolding next to Turkish waters, complicating Turkey's claim to be the Black Sea's neutral safety guarantor.Targeting the oil-money fleetHitting sanctioned shadow-fleet tankers mid-ship-to-ship-transfer attacks the specific mechanism — STS transfers that disguise cargo origin — by which the fleet moves up to 30% of Russia's seaborne oil, turning Ukraine's drones into a sanctions-enforcement arm against vessels the West only lists on paper.Ankara's straits dilemmaThese tankers reach the Black Sea through the Turkish straits Ankara controls; their being struck there spotlights that Turkey lets shadow-fleet traffic transit while condemning attacks on shipping, a tension between its sanctions non-participation and its civilian-safety rhetoric. - 25 May 2026 Rosatom's Akkuyu nuclear plant nears Unit 1 startupAkkuyu, Mersin (Turkey)
Rosatom's Akkuyu Nuclear Power Plant in Mersin, Türkiye, is in final testing and commissioning of Unit 1, with hydraulic testing, loading of imitation fuel assemblies and hot/cold functional testing under way, and a 350-ton bridge crane installed in Unit 3's turbine hall. The 4,800 MW plant of four 1,200 MW reactors is expected to meet about 10% of Turkey's electricity demand, with the first reactor slated to come online in the coming months.
A Russian-built strategic assetAkkuyu is built, financed and to be operated under Russia's state firm Rosatom at a cost above $20bn — a generational dependency that gives Moscow a foothold in 10% of Turkey's power supply and is the single largest reason Ankara cannot treat Russia as an adversary even amid Black Sea strikes.Sanctions-proofing by designBringing Unit 1 online during the war demonstrates that the flagship Russia–Turkey project is proceeding untouched by the sanctions Western states apply elsewhere — Turkey's non-participation in sanctions is not abstract policy but a live reactor being fuelled by a Russian state company.Energy security cuts both waysAkkuyu meeting 10% of demand reduces Turkey's gas-import reliance — including on Russian gas — even as it deepens nuclear dependence on Russia; the plant simultaneously diversifies Turkey's fuel mix and ties its grid to a Russian operator, the contradiction at the heart of the balancing act. - 21 May 2026 Turkish firm Armelsan completes sea trials of Nusrat-1915 mine-hunting sonarTurkey (Black Sea trials)
On 21 May 2026 Turkish defence company Armelsan completed sea trials for its domestically developed Nusrat-1915 mine-hunting sonar, which it says doubles detection range and performance versus current foreign sonars. The system will be integrated into Turkish Navy vessels starting with Engin-class ships, with full-fleet capability expected by end of 2027. Armelsan attributed the development to strategic needs in the Black Sea and Gulf and is also building a compact sonar suite for unmanned surface and underwater vehicles.
The drifting-mine threatA new mine-hunting sonar answers a specific Black Sea hazard the war created — sea mines breaking loose and drifting toward Turkish and Bulgarian shores — a maritime-safety capability Ankara needs precisely because Montreux makes it the steward of straits and littoral that errant mines threaten to close.Import substitution from Russia and the WestDoubling on a domestic sonar that beats 'foreign sonars' fits Turkey's pattern of building indigenous systems to escape dependence on both Russian and NATO suppliers — the same self-reliance logic behind Akkuyu localisation and the PIRANA USV, applied to undersea detection.Naming the Nusret legacyBranding it 'Nusrat-1915' invokes the minelayer Nusret that helped repel the Allied fleet at the Dardanelles in 1915 — a deliberate signal that Turkey frames Black Sea mine warfare as a sovereign, historically rooted mission rather than a NATO-assigned task. - 18 May 2026 German bust names Turkey as transit for a €30m dual-use sanctions-evasion network to RussiaTurkey (transit) / Germany
On 18 May 2026 German prosecutors and intelligence services disclosed a major sanctions-evasion network that allegedly supplied Russia's military industry with European dual-use technology through Turkey and shell companies. A Lübeck-based firm, Global Trade, is suspected of procuring microcontrollers, sensors and other components for Russian defence entities; the BND penetrated the network and tracked roughly 16,000 shipments worth over €30 million. The case spotlights how third-country intermediaries — here, routed via Turkey — circumvent Western export controls.
Turkey as the back doorTurkey being the named transit country for 16,000 shipments of microcontrollers and sensors to Russian defence firms makes concrete the cost of its sanctions non-participation: Turkish territory functions as the conduit Western export controls cannot close, a direct material contribution to Russia's war machine.Component-level leverageThe intercepted goods are dual-use electronics — microcontrollers and sensors that go into Russian weapons — not bulk trade, so the network feeds precisely the precision components Russia struggles to make domestically, raising the strategic significance of the Turkey route beyond ordinary commerce.Allied friction, not Turkish actionThe case was broken by Germany's BND, not Turkish authorities, and surfaces as a NATO ally exposing a route through another ally's territory — the kind of quiet intra-alliance friction that accumulates against Turkey's balancing act without producing a formal rupture. - 3 18 May 2026 Erdogan reaffirms Crimean Tatar support on 82nd deportation anniversaryAnkara
On 18 May 2026 Ukraine marked the 82nd anniversary of the 1944 Soviet deportation of the Crimean Tatars, with Zelensky calling it genocide and the Verkhovna Rada urging international recognition; at least a third of the 183,144 deported died. Memorial events were held in Ankara, where Ukraine's Ambassador Nariman Dzhelyal accused Russia of continuing repression since the 2014 annexation, including settling 500,000–800,000 Russians. Turkey's Foreign Ministry marked the anniversary and President Erdogan reaffirmed Türkiye's commitment to defending Crimean Tatar rights internationally, with over 270 Crimean Tatars among political prisoners.
Kinship as a pro-Ukraine anchorTurkey's ethnic and historical kinship with the Crimean Tatars gives Ankara a durable reason to oppose Russia's Crimea occupation that energy and Akkuyu cannot override — a values-based commitment that keeps Turkey from ever fully recognising the annexation even while it trades with Moscow.Non-recognition made specificErdogan defending Crimean Tatar rights 'in the international arena' is the operative form of Turkey's non-recognition of the 2014 annexation — not a one-off statement but a standing diplomatic position that ranges Turkey against Russia on Crimea's status irrespective of the commercial relationship.Shared platform with KyivHolding the commemoration jointly in Ankara, with Ukraine's ambassador citing demographic engineering of 500,000–800,000 settlers, puts Turkey and Ukraine on one stage against Russian occupation — a visible alignment on Crimea that coexists with Ankara's refusal to sanction Moscow. - 8 May 2026 Turkish MP rules out negotiating with Russia over Crimean Tatar prisonersTurkey
In an interview around 8 May 2026, Yıldırım Tuğrul Türkeş, chairman of the Türkiye–Ukraine Friendship Group, said negotiating with Russia for the release of Crimean Tatar prisoners is impossible because Russia considers them its own citizens. He cited Turkey's special kinship ties with Crimean Tatars and noted that over 270 Crimean Tatars are among 520 politically motivated prosecutions in occupied Crimea, while praising Ukraine's recognition of the Mejlis as the Crimean Tatars' sole representative body.
A limit Ankara won't barterStating that Russia's claim on Crimean Tatars as 'its own citizens' makes negotiation impossible draws a concrete red line: Turkey will mediate the war broadly but treats the Tatars' status as non-negotiable, a fixed point where its values override its mediator flexibility.Endorsing the Mejlis over MoscowPraising Ukraine's recognition of the Mejlis as the Tatars' sole representative body is an implicit rejection of Russian authority over occupied Crimea — Turkey backing Kyiv's institutional framing of the peninsula, a pointed alignment beneath the surface neutrality.Prisoner numbers as evidenceCiting 270-plus Crimean Tatars among 520 political prosecutions converts the kinship rhetoric into a documented human-rights indictment of Russian rule, the kind of specific charge that keeps Turkish public opinion anchored against Moscow on Crimea. - 4 May 2026 Russian gas via TurkStream falls as Turkey becomes Europe's sole pipeline routeTurkStream (Russia–Turkey–Europe)
Russia's average daily gas deliveries to Europe via the TurkStream pipeline fell 1.7% year-on-year in April 2026 to 41 million cubic metres and were down 25.5% from March, with monthly supplies of 1.23 bcm. The decline came amid higher prices following the Strait of Hormuz closure, with Turkey now the sole transit route for Russian pipeline gas to Europe after the Ukraine route closed. For January–April 2026, exports were nonetheless up 7.3% year-on-year at about 6.2 bcm.
Turkey as Russia's last gas gatewayWith the Ukraine transit route shut, TurkStream through Turkey is the only remaining pipeline carrying Russian gas to Europe — a chokepoint that hands Ankara unique leverage over both Moscow's revenue and Europe's supply, deepening the energy entanglement that keeps Turkey from sanctioning Russia.Volume up, not down, year-to-dateDespite the April dip, four-month exports rose 7.3% — evidence the Russia–Turkey gas relationship is expanding, not winding down, even as the war's Black Sea violence escalates; the commercial trend runs opposite to the diplomatic friction over shipping strikes.Hormuz spilloverThe price spike driving the dynamics is attributed to the Strait of Hormuz closure, showing how a separate Gulf crisis raises the strategic value of the Russia–Turkey gas corridor — Turkey's role as Europe's supplier of last resort grows precisely when alternative routes are disrupted. - 4 May 2026 Von der Leyen groups Turkey with Russia and China as an influence to resistHamburg / EU
On 4 May 2026, at a Die Zeit event in Hamburg, European Commission President Ursula von der Leyen said Europe must be 'completed' to avoid falling under Russian, Turkish or Chinese influence. The remark grouped NATO member and EU candidate Turkey with Europe's principal strategic rivals, which analysts read as recognition of Turkey's growing geopolitical autonomy. The framing marked a shift in European strategic psychology toward viewing Ankara as an independent actor rather than a partner.
Lumped in with MoscowAn EU leader bracketing Turkey with Russia and China is the clearest sign that Ankara's refusal to sanction Moscow and its independent line have cost it standing in Brussels — the reputational price of the balancing act, paid in being treated as a rival vector rather than an ally.Autonomy read as threatAnalysts reading the remark as acknowledgment of Turkey's 'geopolitical weight and autonomy' shows the balancing act working as intended — Ankara has made itself a power Europe must reckon with — while simultaneously backfiring, since that same autonomy is what gets it grouped with adversaries.Candidate-status contradictionNaming Turkey a threat 'despite its EU candidate status and NATO role' exposes the structural incoherence of Turkey's position: formally inside both Western clubs yet treated as outside them, the diplomatic squeeze that constrains how far Ankara can lean toward Russia without losing its Western anchor entirely. - 4 1 May 2026 Turkey files complaint over the 2016 assassination of Russia's ambassadorAnkara
On 1 May 2026 Turkey's National Intelligence Organization (MIT) filed a criminal complaint against Abdullah Bozkurt, a Sweden-based FETÖ-linked suspect, accusing him of orchestrating the 2016 assassination of Russian Ambassador Andrey Karlov in Ankara. The complaint alleges Bozkurt directed the gunman and ran disinformation campaigns; Ankara has repeatedly sought his extradition from Sweden, which has refused. The case revives a flashpoint in Turkish–Russian relations a decade after the killing.
Gesture toward MoscowReopening the Karlov assassination case with a formal complaint signals to Russia that Ankara still treats the 2016 killing as an attack on the bilateral relationship — a goodwill gesture that costs Turkey nothing with Moscow and helps preserve the partnership amid Black Sea friction.FETÖ framingBlaming a FETÖ-linked suspect folds the Russia file into Erdogan's central domestic narrative — that the Gülen movement is behind Turkey's gravest security breaches — letting Ankara pursue a Russia-friendly case in the language of its own internal politics rather than as a favour to the Kremlin.Sweden extradition snagThe unresolved extradition demand on Sweden ties the case to a live intra-NATO dispute, showing the Russia relationship spilling into Turkey's friction with a fellow alliance member — Ankara pressing a Stockholm extradition partly to satisfy a grievance shared with Moscow.
Background
Turkey is a NATO member that armed Ukraine — Bayraktar TB2 drones played a visible role early in the war — and never recognised Russia's annexations, yet refuses to join Western sanctions, arguing it cannot afford to given its balance-of-payments strain. The ties to Moscow are structural: Russia supplies roughly 40% of Turkey's gas and over 70% of its crude, the Russian state firm Rosatom is building Turkey's first nuclear plant at Akkuyu for over $20bn, Russian tourists are a major source of revenue, and Turkey has become a conduit for Russian capital and reflagging. Ankara condemns the invasion in word while keeping every economic channel to Russia open — the definition of its 'strategic ambiguity.' (Sources: European Leadership Network; Atlas Institute; Al Jazeera.)
Turkey's leverage rests on the 1936 Montreux Convention, which gives Ankara sovereign control of the Bosphorus and Dardanelles — the only sea access to the Black Sea. In peacetime it guarantees free passage for civilian vessels and caps non-littoral warships by tonnage and 21-day stay; in war or under threat it lets Turkey close the straits to belligerents' warships. After February 2022 Turkey invoked the war clause and shut the straits to all warships, blocking reinforcement of either navy from the Mediterranean — a move that mostly constrained Russia's Black Sea Fleet and that Ankara guards jealously as the source of its indispensability. (Sources: Wikipedia 'Montreux Convention'; Naval News 2022; The Conversation.)
In July 2022 Turkey, with the UN, brokered the Black Sea Grain Initiative in Istanbul, opening demined corridors from Odesa, Chornomorsk and Pivdennyi under a Joint Coordination Centre staffed by Russia, Ukraine, Turkey and the UN, with Turkey inspecting every merchant ship. It moved nearly 33 million tonnes of grain to 45 countries before Russia quit on 17 July 2023. The deal is the template for Ankara's self-image as the Black Sea's indispensable mediator — the backdrop to Fidan's 2026 warnings that drone strikes on civilian cargo ships threaten the maritime trade the initiative once protected. (Sources: United Nations 'Black Sea Grain Initiative'; UN News 2022.)
To beat the G7 oil price cap, Russia runs a 'shadow fleet' of ageing tankers using flag-swapping, name changes, hidden ownership and ship-to-ship transfers; by 2025 it had more than tripled since 2022 and carried roughly 70% of Russian seaborne oil, generating billions in extra revenue. The EU added 41 vessels to its list in December 2025. These tankers transit the Turkish straits and operate in the Black Sea — which is exactly why Ukraine's HUR began targeting them at sea: the three tankers struck on 28 May off Turkey's coast were all previously sanctioned shadow-fleet vessels, and Ukraine says the fleet handles up to 30% of Russia's seaborne oil exports.
