By Bosphorus News Geopolitics Desk
Cyprus leaders meet Thursday with no agreed route back into formal negotiations, while diplomacy over Lebanon slows and a Turkish research notice off Kastellorizo reaches its final day. Washington is widening its Iran sanctions campaign as disruption around Hormuz and tighter diesel supply feed directly into Türkiye's energy outlook.
Cyprus
Leaders Meet Thursday With Negotiating Method Still Unsettled
Turkish Cypriot leader Tufan Erhürman and Greek Cypriot leader Nikos Christodoulides meet Thursday at 11 a.m. in their last scheduled session on the island before the United Nations General Assembly high-level week in New York.
Their negotiators, Mehmet Dânâ and Menelaos Menelaou, met Monday to prepare the session around three areas: substance, methodology and confidence-building measures. Work is continuing on the record of earlier convergences, but the two sides have still not agreed how those elements would lead into a new formal round.
The Sept. 17 meeting has two unresolved tasks: what remains on the table and how the two sides would actually enter another negotiating process.
Filo Jet Search Reaches Deep-Water Wreck
The specially equipped Optimus Prime has begun work over the Filo Jet wreck off Kyrenia, where 14 people remain missing after the Aug. 30 sinking.
The wreck lies at about 554 meters, beyond the reach of earlier operations. Turkish Cypriot Prime Minister Ünal Üstel and Deputy Prime Minister Fikri Ataoğlu boarded the vessel Monday as teams prepared to inspect sections that have not yet been examined.
The sinking is also feeding into the political debate over maritime oversight. Republican Turkish Party (CTP) leader Sıla Usar İncirli has proposed separating port management from safety supervision and establishing a Maritime Department responsible for registration, surveys, voyage safety and technical inspections. She also wants seafarers to have the right to refuse a voyage when they judge conditions clearly unsafe.
Israel-Lebanon Front
Formal Talks Move to October After Deadly Week in Southern Lebanon
Israeli and Lebanese ambassadors are due to meet at the US State Department in Washington this week, but the next formal negotiating round in Rome has been pushed into October.
The delay follows another deadly week in southern Lebanon. Israeli strikes on Kfar Rumman on Sept. 7 killed at least 13 people, including six children and three women, according to Lebanon's Health Ministry. Twelve were killed when a residential building was hit, while a separate drone strike killed a medic and wounded two others.
The Israeli military said it had targeted people transferring weapons in the area and was reviewing reports of civilian casualties. The strikes came during Israeli operations around the Ali al-Taher ridge, where the military said it had destroyed a Hezbollah underground complex.
Washington is keeping the diplomatic channel open, but the Rome round will now come after several more weeks of fighting. Jewish holidays, a Paris conference supporting the Lebanese Armed Forces and preparations for the UN General Assembly were cited in connection with the delay.
Greece and the Aegean
Turkish Research Notice off Kastellorizo Reaches Final Day
Türkiye's Navigational Telex (NAVTEX) 0862/26 for scientific work by the R/V TÜBİTAK MARMARA southwest of Kastellorizo expires Tuesday after running from Sept. 1 to 15.
Greece issued a counter-NAVTEX disputing Antalya station's authority and argued that one of the research points lay over an area Athens regards as part of its continental shelf. Greek reporting said a Hellenic Coast Guard vessel monitored the Turkish ship from a distance.
No extension of the Turkish notice had been announced by publication time.
A second survey file is moving closer to activity farther west.
Kasos Survey Window Opens as French Vessel Is Prepared
Greece is preparing another seabed survey phase for the Great Sea Interconnector (GSI) around Kasos and Karpathos, where Greek and Turkish naval units operated in the same waters during the July 2024 survey dispute.
Greek reporting says a French-flagged vessel will conduct unfinished work for cable manufacturer Nexans between late September and early November. France is expected to notify Türkiye and other coastal states before the operation, although neither the Élysée nor Nexans has publicly confirmed that arrangement.
Six temporary drone restrictions reported around Kasos, Karpathos, Saria and Armathia are due to take effect Sept. 16. No official source has linked them to the GSI work.
The return to the Kasos survey area again puts the two positions directly against each other. Ankara says prior coordination is required in waters where it claims jurisdiction; Athens rejects the Turkish claim.
Türkiye and Greece Return to the 1922 Record
Türkiye and Greece exchanged official statements over the Sept. 14 Greek commemoration of what Athens calls the "Genocide of the Greeks of Asia Minor."
Türkiye rejected the terminology and cited Article 59 of the Treaty of Lausanne. The article records Greece's obligation to make reparation for damage caused in Anatolia by acts of the Greek army or administration contrary to the laws of war, while also recording Türkiye's decision to renounce those claims because of Greece's financial position after the war.
The latest exchange over 1922 and Lausanne brings another dispute into a bilateral agenda already occupied by maritime jurisdiction and survey activity.
Maritime Security
Tuğberk İmamoğlu Captain Found Dead Near Search Area
The body recovered about five kilometers from the area where the Tuğberk İmamoğlu sank has been identified as the ship's captain, Yaşar Kayhan.
The vessel went down after colliding with the tanker Alsu south of Silivri on Sept. 2. Ten crew members had been missing since the accident, leaving nine still unaccounted for after Kayhan's identification.
Search operations and the prosecutor's investigation continue.
Sanctions and Finance
US Extends Iran Campaign to VTB and Türkiye-Based Companies
The United States imposed new Iran-related sanctions on Russia's VTB Bank, accusing the lender of establishing correspondent relationships with sanctioned Iranian banks and helping Moscow and Tehran build alternative financial channels.
The US Treasury tied the action explicitly to recent measures against financial institutions in Türkiye and the United Arab Emirates. It also warned that foreign banks continuing certain transactions with VTB could face secondary-sanctions exposure.
Treasury said it was meeting global financial institutions this week over Iranian revenue, procurement and financial networks.
Washington has also targeted Türkiye-based companies. Sky Phoenix Hava Yolları was sanctioned on Sept. 8 over alleged assistance in transferring US-origin aircraft to Mahan Air. S Sistem Lojistik and Mes Cargo were named over alleged cargo and commercial services for the Iranian airline.
Those measures followed the Sept. 4 designation of Golden Global Yatırım Bankası and two Türkiye-based subsidiaries. Golden Global rejected the allegations, saying the people and institutions cited by Washington were not its customers and that it had carried out no direct or indirect transactions with them.
Hormuz and Energy
Washington and Tehran Trade Claims Over Damaged Tanker
Iran's Islamic Revolutionary Guard Corps (IRGC) said the Panama-flagged tanker El Gaia struck naval mines south of the Strait of Hormuz and exploded.
United States Central Command (CENTCOM) rejected that account, saying an Iranian missile disabled the tanker last month and an Iranian drone hit it again over the weekend off Oman. CENTCOM said a regional partner was towing the vessel.
India said 13 of the ship's 14 Indian crew members had been rescued and one remained missing.
Commercial movement through Hormuz continues to shrink. Preliminary Kpler data showed only four commodity vessels transited the strait on Monday, down from 10 a day earlier and far below the prewar norm.
Oman has meanwhile postponed a planned regional meeting on a proposed navigation arrangement. Foreign Minister Badr Albusaidi said more time was needed to build consensus.
Saudi Arabia's East-West pipeline, which had been carrying roughly 4 million barrels per day toward the Red Sea port of Yanbu as an alternative to Hormuz, remains offline. Renewed Houthi missile and drone attacks on Saudi targets have added another constraint along the export route.
Diesel Squeeze Links Ukraine War to Türkiye's Import Bill
US President Donald Trump has urged Ukraine to stop striking Russian refineries, arguing that the attacks are worsening the global diesel shortage.
Ukraine's long-range campaign has reduced Russian refining capacity, while Moscow has extended diesel export restrictions through the end of September. Gulf supply is tight as well. The International Energy Agency (IEA) put Gulf net diesel exports at about 390,000 barrels per day in August, roughly one quarter of prewar levels.
Türkiye is replacing Russian barrels in that market. Russia's share of Turkish diesel imports fell to about 20 percent in August, while shipments from India and the United States reached record highs. With Türkiye sourcing more diesel outside Russia, higher replacement costs now depend increasingly on what India, the Gulf and the US market can supply.
Türkiye's medium-term programme assumes a very different price environment. It puts Brent at an average $76 a barrel in 2027 and expects the energy import bill to fall from $71 billion this year to $66 billion next year.
The programme had already raised Türkiye's energy-cost and inflation path. S&P Global Energy now expects Brent to average $86 in 2027 and no longer assumes Middle Eastern crude production will return fully to prewar levels before year-end. That leaves Türkiye's 2027 oil assumptions closely tied to the timing of a Gulf recovery.
Türkiye and Syria
Fidan Ends Damascus Visit With Erdoğan Trip Under Discussion
Foreign Minister Hakan Fidan completed a two-day visit to Syria after meeting President Ahmed al-Sharaa, Foreign Minister Asaad Hassan al-Shaibani and Interior Minister Anas Khattab.
Fidan said preparations for a planned visit by President Recep Tayyip Erdoğan to Damascus were discussed. Ankara is also pressing for implementation of the Syrian Democratic Forces' (SDF) dissolution and integration into Syrian state institutions.
The SDF implementation dispute and Erdoğan visit plan are moving ahead while Russia restores part of its military logistics on the Syrian coast.
A four-vessel Russian convoy delivered supplies to Tartous and Hmeimim in the first such operation since Moscow and Damascus reached an Aug. 9 agreement allowing Russian forces to remain while military facilities are converted into joint training centers.
Russia's resupply restores a military logistics line on the Syrian coast as Ankara's talks with Damascus move toward SDF implementation and a possible Erdoğan visit.
Black Sea
Romania Neutralizes Explosive Drone Debris as Türkiye Joins Regional Drills
Romanian authorities dealt with several drone incidents along the coast and in Black Sea waters on Sept. 11, including two finds containing explosives.
At Periteașca in Tulcea County, one of two drone fragments found on the beach carried an explosive charge and was neutralized. Farther south at Edighiol-Periboina in Constanța County, military teams located debris from four drones, including an interceptor drone carrying explosives. Two additional fragments recovered from the Black Sea about 46 nautical miles east of Midia posed no pyrotechnic hazard.
The incidents come as the western Black Sea threat profile changes. Discoveries of unmanned aerial vehicles, unmanned surface vessels and unexploded weapons in Romanian, Bulgarian and Turkish waters have risen sharply over the past six months, with UAV and USV finds increasing from 13 to 41.
The 208 percent rise in drifting unmanned-system and weapons discoveries is coinciding with a denser exercise schedule.
Türkiye is participating in Romania's Burebista live-air and Eastern Shield air and drone defense exercises from Sept. 11 to Oct. 2. Turkish forces are also taking part in Triton-2026, a mine-warfare exercise hosted by Bulgaria. Bulgaria separately confirmed the transit of Turkish military personnel and equipment heading to Romania.
South Caucasus
Fidan Meets Bayramov in Baku
Foreign Minister Hakan Fidan began his two-day visit to Azerbaijan on Tuesday and held a one-on-one meeting with Azerbaijani Foreign Minister Jeyhun Bayramov in Baku.
Azerbaijan's Foreign Ministry confirmed the meeting, but no substantive readout had been released by publication time.
The visit comes as the Armenia-Azerbaijan peace process, bilateral defense ties, transport links and energy cooperation remain active across the Türkiye-Azerbaijan agenda.
Türkiye
39 Detained in Multi-Province Security Operation
Turkish authorities detained 39 people in an Istanbul-led operation targeting alleged links to the Marxist-Leninist Communist Party (MLKP), Communist Party of Türkiye/Marxist-Leninist-Turkish Workers and Peasants Liberation Army (TKP/ML-TİKKO), Revolutionary Socialist Workers' Movement-Kaldıraç (DSİH-Kaldıraç) and Maoist Communist Party (MKP).
Prosecutors identified 52 suspects. Eight were believed to be abroad, two were already in prison and three remained at large. AA reported raids in İstanbul and nine other provinces, while IHA reported an additional operation in Elazığ.
LGBTQ+ Groups Face Investigations and Online Restrictions
Türkiye's Justice Ministry said judicial proceedings were under way against 162 suspects, nine associations and 13 businesses in investigations spanning 15 provinces.
Authorities have also imposed access restrictions on numerous websites and social media accounts linked to LGBTQ+ organizations, including Kaos GL.
Justice Minister Akın Gürlek said financial investigators had identified large transfers from foreign public institutions and organizations to what he described as "associations promoting LGBT and immorality." He said investigators were still examining the source of the funds and whether the transfers were connected to the alleged offenses.
Technology and Infrastructure
Türkiye Sets $10 Billion AI Infrastructure Target
Türkiye's 2026-2030 Artificial Intelligence Action Plan aims to mobilize at least $10 billion in investment and raise AI and data-center installed power to at least 1 gigawatt by 2030.
The plan targets one exabyte of storage, 100 terabits per second of backbone capacity and at least 10 terawatt-hours of annual low-carbon electricity purchases. Electricity supply and grid access are built into the expansion plan, including decisions over where the planned AI Growth Zones will be located.
Antalya Congress Follows Artemis Accession
Türkiye's Aug. 31 accession to the Artemis Accords will be followed by the 77th International Astronautical Congress in Antalya on Oct. 5-9, the first time the event has been held in Türkiye.
Organizers received a record 8,330 abstracts from 108 countries, including 1,810 submissions from Türkiye. The congress also arrives as Türkiye prepares its AYAP-1 spacecraft for a planned lunar mission in 2027.
Balkans
Hauliers Postpone EU Border Blockade
Western Balkan hauliers did not begin the planned border blockade on Monday.
The Serbian organizing committee had postponed the action indefinitely on Sept. 11 after talks with the European Union Office in Serbia, citing progress toward a timetable for addressing visa restrictions affecting professional drivers. Carriers in Bosnia and Herzegovina subsequently withdrew from the coordinated action.
Correction: The Sept. 14 Bosphorus News brief described the regional blockade as still pending. The action had already been postponed.
The underlying dispute remains unresolved. Transport groups are seeking an arrangement that would allow professional drivers to work across the Schengen area without breaching the 90-days-in-180 rule.
Vučić Sets Sept. 27 Resignation Before Oct. 25 Vote
Serbian President Aleksandar Vučić said he will resign on Sept. 27 and run for prime minister in the Oct. 25 snap parliamentary election.
The election follows almost two years of student-led protests and comes as Serbia's relationship with the European Union faces another political strain. Earlier this month, the military-honors funeral of convicted Bosnian Serb wartime commander Ratko Mladić drew criticism from European Union leaders and Türkiye.
The resignation plan, snap election and Mladić funeral dispute sends Serbia into the campaign with its domestic political crisis and its relationship with Brussels unresolved.
Bosphorus Read
Thursday's Cyprus meeting starts with an unusually clear list of unresolved work. The two sides have narrowed their preparations to substance, methodology and confidence-building measures, but they still lack an agreed procedure for turning that work into formal negotiations.
In the southeastern Aegean, Türkiye's Kastellorizo research notice expires just as Greece prepares another Kasos survey. Neither file has produced a new confrontation at sea. The legal disagreement remains active, however, because Ankara and Athens still reject each other's authority over notification and coordination in the waters concerned.
Only four commodity vessels crossed Hormuz on Monday. Saudi Arabia's main east-west bypass remains offline, Gulf diesel exports are well below prewar levels and Russian refineries are being hit by Ukraine. Türkiye has already changed where it buys diesel; the next question is what those replacement barrels cost when several alternative suppliers are constrained at once.
Washington is tightening the financial side separately. Golden Global Bank was followed by Türkiye-based aviation and logistics companies, and VTB is now under new Iran-related measures as Treasury warns foreign banks about secondary-sanctions exposure. Foreign banks and Türkiye-based companies dealing with Iran-linked networks now face a higher risk that ordinary transactions trigger US sanctions exposure.
