European Council President António Costa gave the Cyprus settlement process fresh EU backing days before the island's leaders meet again. Off Kyrenia, the Filo Jet inquiry is moving from rescue operations into technical evidence and court testimony, while disruption from the Black Sea to Hormuz is changing shipping routes, grain purchases and energy prices.

Costa Reaffirms EU Backing for Cyprus Reunification
European Council President António Costa reaffirmed the European Union's commitment to the reunification of Cyprus during talks with Republic of Cyprus President Nikos Christodoulides in Nicosia on Friday.
Costa said the EU supports UN Secretary-General António Guterres' efforts toward a negotiated settlement in line with UN Security Council resolutions and international law. He also pointed to the appointment of European Commissioner Raffaele Fitto as the EU's Special Representative for Cyprus.
Christodoulides and Turkish Republic of Northern Cyprus (TRNC) President Tufan Erhürman are due to meet on Sept. 9 after their Sept. 2 session was postponed following the Filo Jet disaster. The two leaders agreed last month to meet at least weekly as efforts continue to prepare the ground for a broader UN format.
GSI Review Continues as TÜBİTAK Marmara Moves North
Republic of Cyprus Finance Minister Makis Keravnos said the Great Sea Interconnector (GSI) still requires an updated assessment of its economic and technical elements before Nicosia takes its next decisions on the Cyprus-Greece electricity link.
Akel leader Stefanos Stefanou has separately asked how French infrastructure investor Meridiam's acquisition of 66 percent of the Greek holding company behind the GSI changes the project's ownership, financing, construction responsibilities and Cyprus' possible participation.
No new survey notice or replacement cable-survey vessel has been announced.
A separate research mission in the same maritime dispute shifted position this week. Greek tracking reports said the R/V TÜBİTAK Marmara, which had been operating south of Kastellorizo, was heading north toward the Turkish coast and Didim by Thursday evening. The Turkish scientific-research notice covering the mission remains valid until Sept. 15.
The movement follows this week's reciprocal diplomatic notes over marine parks and Greek planning frameworks and Greece's €3.035 billion Achilles Shield air defense agreement with Israel. Turkish and Greek authorities had not announced a new operational phase for the TÜBİTAK Marmara mission by Friday morning.
Syria
SDF Integration Leaves Foreign Fighters and YPJ Status Unresolved
Türkiye's Defense Ministry rejected claims that foreign elements affiliated with the Syrian Democratic Forces (SDF) would leave Syria and that some would enter Türkiye. The ministry said it continues to follow the SDF dissolution process under the principle of a single Syrian state and army.
The fate of the Women's Protection Units (YPJ) remains unsettled. YPJ commander Nowruz Ahmed told Reuters that Damascus rejected a proposal to preserve the force as an organized brigade or battalion within the military. Talks with the Interior Ministry are continuing over other possible roles.
What remains to be verified is concrete: where weapons are registered, who commands former formations and how foreign fighters are handled as existing structures are dismantled.
Ankara and Damascus are advancing on another track. Türkiye's Defense Ministry said Turkish and Syrian forces completed a second floating bridge across the Euphrates on Aug. 30 to replace a crossing destroyed by flooding.

Kyrenia Toll Reaches 10 as Inquiry Turns to the Sailing Decision
The confirmed death toll from the Filo Jet disaster stood at 10 on Friday morning, with 18 people still missing. Of the 267 people aboard, 239 were rescued.
TCG Işın and TCG Alemdar are continuing robotic operations around the wreck at a depth of about 550 metres, including work to recover the missing and locate the vessel's black box.
The technical investigation is also under way. A delegation from Türkiye's Transport and Infrastructure Ministry, led by Marine Accidents Investigation Department head Durali İşler, is examining the vessel's documents and technical and structural condition. The ministry said two Türk Loydu specialists would join the work on Friday.
Court proceedings have moved the inquiry back to the hours before departure. Police told the Kyrenia District Court that Taşucu port was closed until 3 p.m. on the day of the casualty, that the master decided to sail and that another officer had advised against departure because of the conditions. The court was also told that two international certificates were missing and that investigators were examining whether the vessel should have reduced speed and returned after water ingress was detected.
Those allegations have not been established as fact by the court. Nine suspects remain in custody under an eight-day extension.
The technical and criminal inquiries run alongside the documentary questions identified in Bosphorus News' review of the Filo Jet papers. The released records showed that the master's underlying certificate was issued by Honduras and that he held a Turkish Cypriot endorsement valid on the day of the casualty. They did not resolve the separate craft-and-route type-rating requirement under the High-Speed Craft Code.
The political consequences are already visible. Prime Minister Ünal Üstel removed Public Works and Transport Minister Erhan Arıklı, whose Yeniden Doğuş Partisi (YDP) then withdrew from the coalition. The remaining National Unity Party and Democratic Party bloc holds 25 seats in the 50-seat Assembly. Republican Turkish Party leader Sıla Usar İncirli says her party will seek a parliamentary inquiry into the disaster.
Two ALSU Officers Arrested as 10 Sailors Remain Missing
Two ALSU officers, including master Ahmet Erarslan and Murat Evciman, were arrested over the Sept. 2 collision that sank the Turkish-flagged cargo vessel Tuğberk İmamoğlu about 18 nautical miles south of Silivri.
Four other suspects were released under judicial supervision. None of Tuğberk İmamoğlu's 10 crew members has been found.
Investigators have requested ship registry and class documents, port state control records, radar and route data and radio traffic from the hours before the collision. The arrests open the judicial phase of the case without establishing responsibility for the casualty.
Black Sea
Grain Disruption Reaches Danube Queues and Asian Buyers
Asian wheat importers have bought at least 500,000 metric tons of Australian and Argentine grain to replace delayed Russian and Ukrainian cargoes as attacks on vessels and export infrastructure disrupt Black Sea shipments.
The alternative route through the Danube is also congested. Around 80 vessels were waiting to enter the Sulina Canal for Ukraine's Reni and Izmail ports earlier this week, with pilot shortages, inspections and air alerts slowing traffic.
Commercial shipping is adapting before any diplomatic mechanism is in place. Tankers and cargo vessels passing through the Bosphorus have appeared with nets, water tanks and tyres fitted as improvised protection against drones.
Türkiye says it has prepared a proposal for renewed safe navigation and grain traffic and is in contact with Russia and Ukraine. No new agreement has been announced.

Pashinyan Questions Russian Base as Türkiye-Armenia Business Track Advances
Armenian Prime Minister Nikol Pashinyan said Armenia does not regard Russia's 102nd Military Base in Gyumri as a vital necessity and would not object if Moscow decided to withdraw it.
He stressed that Yerevan has not itself raised the question of the base's removal. Russian President Vladimir Putin said Moscow would leave if Armenia decided the presence was no longer wanted.
Pashinyan also said transferring Russia's concession rights over Armenia's railway network to a third country would be the best option for Armenia, although Russian officials say Yerevan has made no formal request to transfer the concession.
The comments coincided with a two-day Armenia-Türkiye Business Forum in Yerevan bringing together companies and business groups from both countries. Participants discussed transport links, an eventual border opening and the cost of doing business across a frontier that remains closed to regular trade. The Van Chamber of Commerce and Industry offered space for a future representative office to coordinate commercial relations if normalization advances.
Chemical Weapons
Syria Begins Destruction of Assad-Era Chemical Materials
Syria has begun destroying chemical materials left from Bashar al-Assad's program under international verification.
The United Nations and the Organisation for the Prohibition of Chemical Weapons (OPCW) confirmed the destruction of 42 aerial bombs as well as chemical-weapons production and storage infrastructure. UN disarmament chief Izumi Nakamitsu said the OPCW had verified irreversible destruction in Syria for the first time since 2014.
Türkiye's Permanent Representative to the United Nations Ahmet Yıldız backed the process and warned that Israeli strikes on suspected chemical-weapons sites could release hazardous material, endanger civilians and destroy evidence needed to establish responsibility for previous attacks.
Israel-Lebanon Front
Iran Warns US Over Possible Israeli Assault on Ali al-Taher
Iran warned the United States that a full-scale Israeli offensive against the Ali al-Taher ridge in southern Lebanon would trigger a large Iranian response, three officials briefed on the message told Reuters.
The warning was delivered through Oman in August. Lebanese security sources cited by Reuters said Iranian Islamic Revolutionary Guard Corps personnel were present around the ridge alongside Hezbollah fighters. Hezbollah has publicly said it controls the position.
Israel disputes the claim that Iranian personnel are deployed there. A White House official also rejected Reuters' account of the Iranian message, saying it was inaccurate.
Israeli forces hold territory south of Ali al-Taher and have identified the ridge as an operational focus, making it one of the clearest points where the Israel-Hezbollah front could draw Iran more directly into fighting on Lebanese territory.

Hormuz Traffic Falls as Brent Holds Above $96
Only four observed commodity vessels crossed the Strait of Hormuz on Thursday, compared with a 10-day average of 15, according to Kpler data cited by Reuters.
The count comprised two medium-range tankers, a Kamsarmax bulk carrier and a Handysize vessel. Ships operating with Automatic Identification System transponders switched off are not captured, so the figure does not represent all traffic through the strait.
Brent crude traded above $96 a barrel on Friday as renewed US-Iran hostilities kept supply risk in the market. That puts oil roughly $30 above the $65.1 Brent assumption Bosphorus News identified in Türkiye's current 2027 government planning baseline.
Vice President Cevdet Yılmaz says the 2027-2029 Medium-Term Program will be presented on Sunday, Sept. 6. The Central Bank of the Republic of Türkiye holds its next Monetary Policy Committee meeting on Sept. 10.
The supply map has already started to move. Energy Market Regulatory Authority data show the United States supplied 570,676 tonnes of crude to Türkiye in June, ahead of Russia's roughly 425,000 tonnes. Russia remained Türkiye's largest supplier when crude and refined petroleum products were counted together. Bosphorus News examined the widening gap between oil prices and Türkiye's planning assumptions on Aug. 31.
Moldova
Airspace Incursion Crosses Transnistria as Drone Cooperation Expands
Moldova's National Army said an unidentified aerial object entered Moldovan airspace from Ukraine near Dnestrovsk in the Transnistrian region during Russian attacks on the Odesa region.
The object crossed the border at 3:50 p.m. and returned toward Ukraine nine minutes later along the same route.
The incident came as Moldovan and Ukrainian border agencies completed talks on the detection, interception and neutralization of drones. The two sides also signed a cooperation agreement covering joint measures and real-time information exchange.
Balkans
Mladić Body Returns to Serbia on Government Plane
The body of former Bosnian Serb military commander Ratko Mladić was returned from The Hague to Serbia aboard a government aircraft after his death while serving a life sentence for genocide, crimes against humanity and war crimes committed during the 1992-95 Bosnian war.
Serbian Justice Minister Nenad Vujić travelled on the flight, and soldiers carried the coffin after it landed in Belgrade.
A Serbian minister had initially said Mladić would receive a state funeral, but the government has not confirmed that plan. President Aleksandar Vučić said tens of thousands of people could attend the funeral.
EU Enlargement Commissioner Marta Kos warned that glorification of convicted war criminals is incompatible with European values and Serbia's membership ambitions. Croatian Prime Minister Andrej Plenković said a Serbian state funeral for Mladić would close the country's door to the European Union.
Bosphorus Read
The Cyprus file is moving faster politically than physically. Costa has put explicit EU backing behind the UN settlement effort and the leaders meet again next week, but the GSI still lacks the decisions needed to put cable surveys back at sea. The TÜBİTAK Marmara moved away from the Kastellorizo area while the Turkish research notice remained in force.
Filo Jet is moving the other way. The search continues at 550 metres, but the investigation is already reaching backward through the voyage: the condition of the vessel, its certificates, the weather, the warnings on the bridge and the decision to leave port. That evidence is now being examined in separate technical, criminal and parliamentary tracks.
Outside Cyprus, the consequences are showing up on commercial routes. Asian wheat buyers are replacing delayed Black Sea cargoes, ships entering the Bosphorus are carrying improvised anti-drone protection, and observed Hormuz traffic remains depressed with Brent above the assumptions Ankara is about to rewrite. Armenia adds a different route question: a Russian military base and Russian-run railway are being openly discussed while Turkish and Armenian businesses prepare for the possibility of an open border.
