Two deep-water searches remain active off northern Cyprus and Istanbul as the Cyprus diplomatic calendar shifts and Athens puts military capability, maritime claims and European defense access into the same week of policy statements. Farther south, US-Iran attacks have reached commercial tankers, Iraq is pushing Mediterranean oil routes through Ceyhan and Baniyas, and fighting is intensifying near Bab al-Mandab.

Filo Jet Toll Reaches 13 as Turkish Navy Runs Second Deep-Sea Search in Marmara
The confirmed death toll from the Filo Jet disaster has risen to 13, with 15 people still missing after Turkish Cypriot Prime Minister Ünal Üstel announced the recovery of another body on Sept. 5.
The Health Ministry has begun taking DNA samples from relatives of the missing for identification work. TCG Işın and TCG Alemdar remain off northern Cyprus with remotely operated underwater systems working around the wreck at a depth of about 550 metres. The voyage data recorder has not been recovered.
The investigation has moved toward decisions made before the vessel sailed. Police told the court that the master's earlier Turkish certificate had lapsed and that he later obtained a Honduran certificate. Investigators are examining the certification and recognition record. Evidence reported from the proceedings also includes a statement from the second officer that Taşucu port had been closed because of the weather and that he advised against departure.
Entertainment restrictions have been extended, while professional organizations have called for tighter inspection and expert oversight of maritime transport.
A second Turkish naval operation is continuing in the Marmara Sea, where all 10 crew members of the Turkish-flagged cargo ship Tuğberk İmamoğlu remain missing after its collision with the tanker MT Alsu south of Silivri on Sept. 2.
TCG Akın located the wreck about 18 nautical miles offshore at a reported depth of approximately 720 metres. The ship was identified using the TCB Istakoz-2 remotely operated vehicle, which filmed its name on the seabed.
Türkiye's Ministry of National Defence said overnight that naval search-and-rescue work was continuing around the clock. No crew member had been recovered in the latest update.
Holguín Cancels Cyprus Visit, Looks Toward New York Meetings
United Nations Secretary-General's Personal Envoy for Cyprus María Angela Holguín has cancelled her planned Sept. 10 visit to the island after doctors advised her not to travel by air, according to reports citing sources familiar with her schedule.
Holguín had initially been expected to arrive on Sept. 7 and attend the Sept. 9 meeting between Republic of Cyprus President Nikos Christodoulides and Turkish Cypriot President Tufan Erhürman. Illness had already pushed her arrival back to Sept. 10 before the visit was cancelled altogether. Under the revised plan, she was expected to remain on the island for the leaders' following weekly meeting on Sept. 16.
The Sept. 9 Christodoulides-Erhürman meeting remains scheduled. Representatives of the two sides are due to meet on Sept. 7.
Politis reported that Holguín hopes to meet both leaders on the sidelines of the United Nations General Assembly in New York.
Christodoulides Pushes UN Convergences Document Before Next Diplomatic Round
Christodoulides said on Sept. 5 that he hoped a document setting out existing convergences in the Cyprus negotiations could be completed before Holguín's next visit.
He said the document would need to be presented to the two sides and the three guarantor powers, Türkiye, Greece and the United Kingdom.
Christodoulides argued that agreement on the existing negotiating acquis could clear the way for an enlarged conference and allow talks to restart from the areas where differences remain. He also said UN Secretary-General António Guterres was expected to meet Erhürman after the official week of the General Assembly.
The United Nations Peacekeeping Force in Cyprus (UNFICYP) has a separate institutional timetable. Security Council Resolution 2815 extended its mandate until Jan. 31, 2027 by a vote of 13 to none, with Pakistan and Somalia abstaining.
Türkiye-Greece
Gerapetritis Counts Türkiye's SAFE Exclusion Among Greece's Gains
Greek Foreign Minister George Gerapetritis has explicitly included Türkiye's absence from the European Union's Security Action for Europe (SAFE) mechanism in a comparison of how the positions of Greece and Türkiye have changed since 2019.
Asked on Sept. 5 about Türkiye's regional influence, Gerapetritis acknowledged the country's size and international partnerships before listing what he described as gains for Greece. He cited Greece's upgraded F-16 fleet and entry into the F-35 program, contrasted that with Türkiye's exclusion from the F-35 program, and added that Türkiye was not part of SAFE.
Gerapetritis referred to SAFE as an €800 billion program. SAFE itself provides up to €150 billion in EU-backed loans. The larger figure belongs to the wider European defense investment effort.
His remarks add a ministerial-level record to the pattern examined by Bosphorus News on Sept. 5 in its analysis of Greek MEP Nikolas Farantouris's interventions over Kasos, maritime jurisdiction and European defense access.
That analysis traced how Greek and Republic of Cyprus maritime positions have increasingly entered separate debates over European borders, defense industry access, SAFE participation and Türkiye's relationship with the European Union. Gerapetritis did not refer to Farantouris, and there is no evidence of coordination between the minister and the MEP.
Gerapetritis also said Greece's maritime spatial plan reaches what Athens regards as the furthest potential limits of the Greek continental shelf and exclusive economic zone under international law. He repeated Greece's position that continental shelf and EEZ delimitation is the only bilateral dispute it would take to international adjudication. Türkiye disputes several of the underlying maritime and Aegean claims and argues that the bilateral dispute contains additional issues.
Mitsotakis Places Achilles Shield Inside Greece's 2030 Defense Plan
Greek Prime Minister Kyriakos Mitsotakis on Sunday placed the F-35, Rafale, Belharra frigates and the planned Achilles Shield air and missile-defense system inside Greece's defense program through 2030.
Speaking at the Thessaloniki International Fair, Mitsotakis said Greece would complete a broad reinforcement of its defense capabilities by the end of the decade.
His remarks came days after Republic of Cyprus Defence Minister Vasilis Palmas linked the Greece-Israel Achilles Shield project to the Republic's security environment and described Türkiye as a common threat faced by Greece, Israel and the Republic of Cyprus.
No trilateral Achilles Shield agreement involving the Republic of Cyprus has been announced.
Athens Protests Turkish Marine Parks as Greek Media Report Renewed UAV Activity
Greece has delivered a formal diplomatic protest in Ankara over Türkiye's declaration of two marine parks and Turkish objections to Greek spatial planning frameworks.
Greek diplomatic sources said Athens rejects the Turkish parks as having no legal effect where they extend beyond what Greece considers Turkish jurisdiction and into areas Athens regards as part of the Greek continental shelf. Turkish officials responded with notes reiterating Ankara's published positions.
Gerapetritis separately told EU foreign ministers at their informal meeting in Ireland that he had briefed them on developments in the Eastern Mediterranean and Aegean and what Greece describes as violations of international law.
Greek media have also reported renewed Turkish UAV activity in the Aegean, including a Bayraktar TB2 flight late on Sept. 3. The specific flight and violation counts remain Greek claims. Bosphorus News has not found a corresponding Turkish tally or a current primary Hellenic National Defence General Staff table confirming all figures circulating in Greek media.

US Strikes Three Iranian Tankers as Fidan and Araghchi Keep Contact Open
US Central Command said American forces struck three Iranian crude oil tankers after the Islamic Revolutionary Guard Corps fired ballistic missiles toward a US aircraft carrier and a guided-missile destroyer.
CENTCOM said the American ships evaded the missiles and no US personnel were injured.
US forces permanently disabled M/T Downy off Kharg Island and M/T Stark 1 near Jask and struck the empty M/T Kylo, also known as Noxen, in the Gulf of Oman. CENTCOM later said Kylo had sunk.
Iran's Revolutionary Guard said it had targeted tankers transiting the Strait of Hormuz and vessels linked to the United States and warned shipping against movements it had not authorized.
Türkiye's Foreign Minister Hakan Fidan spoke by phone with Iranian Foreign Minister Abbas Araghchi late on Sept. 5. Turkish diplomatic sources said the two ministers comprehensively reviewed the latest status of "ongoing negotiations." The Turkish account did not identify those negotiations more specifically or announce a new mediation mechanism.
Iraq Targets 5 Million bpd Export Capacity Through Ceyhan and Baniyas
Iraq says it wants to increase crude export capacity to 5 million barrels per day while expanding routes that reduce its dependence on the Strait of Hormuz.
Oil Minister Basim Mohammed Khudair said Iraq's export capacity had risen to around 3 million bpd since the beginning of September and could reach 5 million once new strategic pipelines are completed.
The Basra-Haditha-Fishkhabur route would connect southern Iraqi production with Fishkhabur near Türkiye and provide access to the Kirkuk-Ceyhan system and Türkiye's Mediterranean terminal at Ceyhan. A western branch from Haditha toward Syria's Baniyas port would create a second Mediterranean outlet.
The projects predate the latest US-Iran naval exchange, but the confrontation around Hormuz has increased the value of routes that can move Iraqi crude toward the Mediterranean.
Yemeni Government Uses Air Power as Fighting Moves Toward Bab al-Mandab
Yemen's internationally recognized government has stepped up airstrikes against Houthi forces as fighting intensifies across western Taiz and southern Hodeidah.
Government aircraft carried out at least 15 strikes against Houthi positions, gatherings and vehicles during the latest fighting, according to Yemeni military accounts.
The air campaign supports ground forces facing a Houthi offensive toward al-Makha, or Mocha, and high ground overlooking approaches to the Bab al-Mandab Strait. Agence France-Presse reported more than 120 people killed during the first two days of the offensive, citing military and medical sources.
The fighting has not moved into the strait itself, but its direction places additional military pressure close to one of the principal shipping passages between the Red Sea and the Gulf of Aden.
Israel-Lebanon Front
Israel Launches New Strikes After Hezbollah Drone Attempt
The Israel Defense Forces (IDF) said it carried out new strikes against Hezbollah personnel, infrastructure and weapons storage sites in southern Lebanon after a Hezbollah drone was launched toward Israeli troops operating inside the security zone.
The IDF said no Israeli soldiers were injured. Associated Press reported three people killed and dozens wounded in the subsequent Israeli strikes.
The exchange follows the fight over the Ali al-Taher ridge, where Israel says it has cleared Hezbollah fighters from underground infrastructure. A Lebanese military official has disputed the extent of Israeli control over the tunnel network.
Israeli Defense Minister Israel Katz has linked a broader Israeli withdrawal from southern Lebanon to Hezbollah's disarmament across the country.
Security Council Resolution 2790 extended the mandate of the United Nations Interim Force in Lebanon (UNIFIL) for a final time until Dec. 31, 2026. The mission is then to begin an orderly withdrawal lasting no more than one year.

Two Greek Pilots Killed in F-4E Crash at Tanagra
Two Hellenic Air Force pilots were killed when an F-4E Phantom II crashed during Athens Flying Week at Tanagra.
The aircraft went down near the 114 Combat Wing during its display flight. Greek authorities have opened an investigation into the cause.
Mitsotakis opened his Thessaloniki speech on Sunday by referring to the deaths before setting out the country's defense plans through 2030.

Türkiye Prepares New Three-Year Programme as Diesel Shock Deepens
Vice President Cevdet Yılmaz is due to present Türkiye's 2027-2029 Medium-Term Programme at the Presidential Complex at 11:00 on Sunday.
The existing program assumed growth of 3.8 percent in 2026, 4.3 percent in 2027 and 5 percent in 2028, with inflation targets of 16, 9 and 8 percent respectively.
Those assumptions preceded the latest energy shock.
Around 900,000 barrels per day of diesel and roughly 350,000 bpd of jet fuel had normally moved from Gulf producers through Hormuz, accounting for about 10 percent and 20 percent respectively of global seaborne supply, according to Vortexa figures cited by Reuters.
US diesel refining margins reached a record intraday level above $108 per barrel last week as supply tightened. Russia has simultaneously extended restrictions on diesel exports through Sept. 30 after Ukrainian attacks damaged refinery capacity and strained its domestic fuel market.
Türkiye has traditionally been a large buyer of Russian refined products and increased diesel imports from India and the United States in August as Russian and Middle Eastern supplies became less reliable.
The energy assumptions in the new Medium-Term Programme will therefore be tested by refined-fuel costs as well as the crude benchmark.
Seven OPEC+ producers are also due to review production policy on Sunday. Market expectations before the meeting pointed to unchanged quotas after the latest stage of the group's voluntary production-cut rollback.
Bosphorus Read
Two search operations open today's brief but have moved into different phases. Filo Jet now combines recovery work with criminal and regulatory scrutiny. Tuğberk İmamoğlu has been located far below the Marmara surface, while the whereabouts of all 10 crew members remain unknown.
The Greece-Türkiye file is accumulating across several institutions. Athens has protested Türkiye's marine parks, Gerapetritis has taken Aegean and Eastern Mediterranean complaints into an EU ministerial meeting and has now cited Türkiye's absence from SAFE in a direct comparison with Greece. Mitsotakis followed by placing F-35s, Rafales, Belharra frigates and Achilles Shield inside Greece's 2030 defense plan.
That sequence adds to the pattern Bosphorus News traced in the Farantouris record: maritime disputes, European defense access and Türkiye's relationship with the EU are increasingly appearing in the same political argument even though their legal categories remain separate.
South of the Eastern Mediterranean, the common pressure point is access to routes. US strikes have reached Iranian tankers, Iraq is advancing Mediterranean outlets through Ceyhan and Baniyas, and Yemen's fighting is moving toward terrain overlooking Bab al-Mandab. Türkiye faces the economic side of that disruption through refined products as Gulf supply tightens and Russia restricts diesel exports.
The Cyprus process has lost Holguín's physical presence for the coming round without losing the leaders' timetable. The Sept. 9 meeting remains in place, while Christodoulides is pressing for a written inventory of convergences that could be shared with the two sides and the three guarantor powers before another enlarged conference.
Several monitored files remain open without a publishable operational change. The Great Sea Interconnector has no confirmed new survey vessel or NAVTEX for a return to the Kasos area. Türkiye's Black Sea safe-navigation proposal has produced no announced Russian acceptance. Reports that a first group of Turkish ISIS detainees has been transferred from Iraq to Türkiye still lack official confirmation.
