On October 25, 2026, the United States called Libya's ratification of its maritime memorandum with Türkiye "unhelpful and provocative," as Egypt prepared its own legal response. Türkiye set dates for seabed surveys toward northern Cyprus and reported new missile and naval-drone tests. Athens rejected the need for Turkish permission to survey the Greece–Cyprus power link, as Russia claimed fresh attacks on merchant ships in the Black Sea.
Eastern Mediterranean & Cyprus
US Calls Türkiye–Libya Maritime Pact Ratification "Provocative"
The US State Department called the announcement of Libya's ratification of the 2019 Türkiye–Libya maritime memorandum "unhelpful and provocative" in a response to Kathimerini published October 25, saying the announcement had raised regional tensions. In its October 22 response, Washington urged negotiations but stopped short of criticizing the vote. Washington did not announce sanctions or a new legal finding.
Egypt Prepares Legal Challenge to Türkiye–Libya Maritime Deal
Egypt is assembling a legal file on the Türkiye–Libya maritime memorandum, Foreign Ministry spokesman Nader Zaki said in remarks reported October 25. Cairo is studying possible action against exploration or drilling in contested waters while continuing diplomatic contacts with Ankara, Tripoli, Athens and Nicosia. It has not announced a court filing.
Türkiye Issues NAVTEX for Gas Pipeline Surveys Toward Northern Cyprus
A Turkish navigational warning issued October 23 lists offshore survey work between October 26 and December 31 along a proposed gas connection to northern Cyprus. The NAVTEX names four vessels — Denar Pathfinder, Denar Echo, Denar Explorer and Kırıcı — and 12 coordinates. The notice covers survey activity, not pipeline construction.
Greek Cypriot Negotiator Rejects New Conditions for Cyprus Talks
Greek Cypriot negotiator Menelaos Menelaou argued in an October 25 interview that the understandings reached before the collapse of the 2017 Cyprus talks should remain on the table, including those on security and guarantees. He opposed new preconditions and criticized Ankara's position. His comments came two days before a planned meeting between Nikos Christodoulides and Tufan Erhürman.
Cronos Gas Contracts Valued at Up to $1.8 Billion Ahead of Signing
Infrastructure contracts for the Cronos gas field are expected to be worth $1.3 billion to $1.8 billion, according to Cypriot reporting citing government sources. A signing ceremony is scheduled for October 26, after President Nikos Christodoulides meets Eni executive Guido Brusco. The project would send gas to Egypt for processing and export, with first production targeted for 2028. The contract value has yet to be finalized.
Greece & Europe
Athens Rules Out Turkish Permission for GSI Cable Surveys
Greek government spokesman Pavlos Marinakis said October 25 that applications connected with the Great Sea Interconnector (GSI) surveys had been submitted to Greek authorities, not Türkiye. Athens considers navigational notification distinct from a request for authorization. The surveys have yet to restart amid disputes over maritime jurisdiction, costs and cable production schedules.
Dendias Questions Turkish F-35 Sale, Sets 15,000-Drone Capacity Target
Greek Defense Minister Nikos Dendias again questioned a possible US sale of F-35 fighters to Türkiye in an October 25 interview. He also outlined plans to expand Greece's drone-making capacity from roughly 5,000 units a year at two facilities to 15,000 through another facility and six mobile units by year-end. The 15,000 figure represents planned capacity rather than actual production.
Serbia Votes as Bulgaria's Presidential Race Heads to Runoff
Serbia voted in an early parliamentary election on October 25 after nearly two years of student-led protests. Aleksandar Vučić resigned as president on September 27 to lead his party into the vote; parliamentary speaker Ana Brnabić is serving as acting president. Results were pending. In Bulgaria, exit polls put Iliana Yotova and Andrey Gyurov ahead in a presidential contest expected to go to a November 1 runoff. Official results were still outstanding.
Defense & Maritime Security
Türkiye's SİPER-2 Missile Demonstrates In-Flight Retargeting
Türkiye's SİPER Product-2 missile hit a newly assigned target after receiving updated guidance in flight, defense officials said October 25. ROKETSAN called it the missile's first successful in-flight retargeting demonstration. The test is separate from the SİPER Product-1 training launch at Sinop on October 21. No service-entry date was given.
TURNAs Trials Shipboard TOLGA, TB2-Controlled PİRANA and AKSUNGUR
The TURNAs-2026 exercise off Antalya brought together three distinct trials: MKE's TOLGA close-in weapon aboard TCG Beykoz, a PİRANA unmanned surface strike directed by a Bayraktar TB2, and an AKSUNGUR flight that deployed acoustic sensors and relayed underwater data to Ankara. The October 25 display involved 18 ships, 11 aircraft and around 1,300 personnel. Seventeen companies supplied 41 systems.
Russia Claims Strikes on Two Commercial Ships Bound for Ukraine
Russia's Defense Ministry said October 25 that it had struck two merchant ships bound for Chornomorsk and Odesa, alleging that they carried military supplies. Reuters could not verify the allegation. The vessels' names, flags and cargoes were not established. In a separate attack off Romania on October 23, three sailors from the Khoryv were reported missing.
Black Sea Shipping Deaths Reach 40 in 2026, FT Reports
An October 25 Financial Times investigation, drawing on data from maritime security firm Ambrey and the International Maritime Organization, reported more than 570 ships struck and at least 40 seafarer deaths in the Black Sea this year. It also described rising insurance bills and disruption to commercial traffic. No equivalent official incident tally has been published.
Gulf & Regional Diplomacy
Greece Backs Saudi Request to Keep Patriot Battery at Yanbu
Greece has responded positively to Saudi Arabia's request to retain the Greek Patriot battery at Yanbu, Prime Minister Kyriakos Mitsotakis told Crown Prince Mohammed bin Salman in Riyadh on October 25. The unit has guarded Red Sea energy facilities since 2021 and intercepted two Iranian ballistic missiles in March. The talks also covered Iran, maritime navigation and the East to Med Data Corridor. Athens gave no new end date for the mission.
Saudi Arabia and Pakistan Ratify Mecca Pact as Türkiye Awaits Review
Pakistan's Foreign Office says Islamabad and Riyadh have completed their domestic ratification steps for the Mecca Joint Defense Agreement. Türkiye's parliamentary Foreign Affairs Committee is due to examine the 16-article pact on October 27. A separate parliamentary mandate would still be required for any Turkish deployment abroad.
Türkiye | Capital Markets & Economy
Türkiye Sigorta Executive Detained as Fund Investigation Widens
Police detained Türkiye Sigorta Deputy General Manager Gürol Sami Özer on October 25 as the capital-markets investigation widened. Former company chief executive Taha Çakmak and 14 other suspects had been remanded a day earlier. Authorities had not publicly detailed the allegations against Özer.
Fund Repayments Reach Reported TL9 Billion; Minister Rules Out Immunity
Prosecution sources cited by Turkish media say 24 people have voluntarily transferred a combined TL9 billion in the fund investigation. A TL100 billion recovery target has also been reported. Neither figure establishes how much money has actually been paid back to investors. Justice Minister Akın Gürlek said repayment would not automatically shield suspects from prosecution.
Türkiye's Renewable Power Capacity Reaches 80.3 GW
Renewable power installations in Türkiye reached 80.3 gigawatts at the end of September, or 63.1% of the country's 127.4 GW installed electricity capacity, Energy Ministry figures released October 25 show. Solar and wind accounted for 43.76 GW together. Domestic energy sources represented 72.1% of installed capacity. The 63.1% figure refers to capacity, not actual generation.
Erdoğan Adviser Leaves Post After Azerbaijan Dispute
Presidential adviser Oktay Saral told journalist Talat Atilla, according to Atilla's October 25 account, that he had left his post on President Recep Tayyip Erdoğan's instructions. His departure followed a dispute over comments he made about restrictions on headscarf-wearing students in Azerbaijan, which President Ilham Aliyev's governing party had criticized. Neither Ankara nor Baku confirmed reports that Azerbaijan sought his removal.
Energy & Strategic Infrastructure
Türkiye and IEA Prepare Global 35% Electrification Target for COP31
Türkiye and Australia are working on a proposal to raise electricity's share of global final energy consumption to 35% by 2035, International Energy Agency (IEA) chief Fatih Birol said ahead of COP31 in Antalya. The "35 by 35" initiative, introduced before October, envisages annual IEA monitoring if governments adopt it. The proposal has not been adopted.
Turkic States Prepare Ankara Summit as Türkiye Takes Chairmanship
Ankara will host the Organization of Turkic States (OTS) leaders' summit on October 30, after a foreign ministers' meeting the previous day. Türkiye is expected to take the rotating chairmanship from Azerbaijan. A new secretary-general, transport links, energy cooperation and an Ankara Declaration are on the agenda. No summit decisions have been adopted.
Bosphorus News Reading
Washington has sharpened its criticism of the announcement that Libya ratified the Türkiye–Libya maritime memorandum, while saying its position on the deal remains unchanged. On October 22, the State Department called for talks; on October 25, it described the Libyan vote as "unhelpful and provocative." Egypt is preparing a legal file, Tripoli has offered to discuss Cairo's objections, and the parliament in eastern Libya has approved a memorandum it once opposed. None of those steps has produced an agreed maritime boundary. Cairo's next move will matter most if it identifies a legal forum, a specific exploration operation and the relief it seeks. A diplomatic protest does not automatically halt offshore work.
Three energy projects around Cyprus face different obstacles. Ankara's new NAVTEX gives crews and dates for preliminary surveys toward northern Cyprus; construction funding and a final pipeline route have not been announced. Cronos has a development plan, an Egyptian export outlet and infrastructure contracts nearing signature. The Great Sea Interconnector is still struggling to reconcile seabed surveys with cost exposure and cable-manufacturing schedules. Athens says it does not need Ankara's permission, but that position does not put a vessel back to work. The next tests are practical: surveys starting on the Turkish-announced dates, Cronos contracts signed on October 26, and a credible timetable for the next GSI offshore campaign. Each would carry more weight than another pledge to press ahead.
Tuesday's scheduled meeting between Christodoulides and Erhürman will take place with the two communities still disputing the terms of practical cooperation. Menelaou wants the understandings preceding the 2017 breakdown retained as the basis for negotiations, including security and guarantees. Erhürman's earlier criticism of a Varosha–Famagusta package raised a more immediate legal question: whether direct trade through a port arrangement could give Turkish Cypriots rights comparable to those sought under the EU's Direct Trade Regulation. One concerns the basis for settlement talks; the other concerns the legal rights attached to interim trade arrangements. The meeting will have substance if it produces an agreed crossing arrangement, a workable trade mechanism or a change in either side's stated position.
Saudi Arabia's request to keep the Greek Patriot unit at Yanbu is separate from its defense agreement with Türkiye and Pakistan. The Patriot battery has guarded infrastructure since 2021 and has already engaged incoming missiles. The Mecca Pact, by comparison, remains subject to Turkish parliamentary scrutiny; any Turkish deployment abroad would require a separate mandate. Riyadh is maintaining an established air-defense mission while negotiating broader mutual-defense commitments. Neither the Greek extension nor Turkish ratification tells us what forces or equipment could ultimately be committed under the pact. Those details will depend on deployment terms and subsequent decisions.
The latest Russian claim of attacks on merchant ships illustrates how difficult incidents in the Black Sea can be to verify. Russia says two merchant vessels headed to Ukrainian ports were hit and carried military supplies; their identities and cargoes have not been independently verified. The Financial Times has meanwhile documented a much larger toll on crews and commercial traffic. Türkiye's proposal to protect civilian shipping will be judged by its mechanics: who identifies vessels, how incidents are investigated, what happens when navigation signals are disrupted, and whether carriers and insurers trust the arrangements. The three sailors reported missing after the Khoryv attack off Romania underline the urgency of such safeguards.
Türkiye's fund investigation now involves arrests, reported asset transfers and ambitious recovery targets. Detentions reflect prosecutorial action, not convictions. The reported TL9 billion in voluntary transfers may help secure assets, but no published accounting yet shows how much has reached investors. A reported TL100 billion target is a goal rather than a recovery total. The brokerage sector may be facing wider losses of confidence, though comparisons between a full trading month and an unfinished one cannot establish their scale. What matters next is how much has been secured, how much can legally be distributed and how much eligible investors actually receive.
Türkiye's latest exercises demonstrated specific capabilities. SİPER Product-2 accepted a new target assignment while airborne. TOLGA operated from a ship. AKSUNGUR dropped acoustic sensors and passed the resulting data ashore. Each will need further integration and repeat testing before it can be assessed in operational service. The same test applies to Greece's ambition to manufacture 15,000 drones annually: capacity figures say little about delivered aircraft or combat readiness. Procurement records, deliveries and field performance will provide a firmer comparison of the two countries' programs.
