Deep-water searches off Kyrenia and Silivri continued Monday as another sinking off Gavdos left dozens unaccounted for, while Hormuz disruption and a threatened Balkan freight blockade put pressure on Türkiye's maritime and overland trade routes.
Cyprus
Deep-Water Vessel Reaches Filo Jet Wreck for New Search Phase
The specialized vessel Optimus Prime reached the Filo Jet wreck area off Kyrenia and was scheduled to begin deep-water work Monday in the search for 14 people still missing after the August 30 sinking.
The Turkish vessel arrived at the site on Sunday evening. Turkish Cypriot Prime Minister Ünal Üstel said crews would try to enter sections of the wreck that earlier teams could not reach at a depth of about 554 meters.
Turkish naval vessels TCG Işın and TCG Alemdar remain involved.
The parliamentary inquiry is also under way, with National Unity Party deputy Sunat Atun appointed to chair the committee investigating the disaster.
Washington Renews Republic of Cyprus Defense Export Access
The United States renewed the Republic of Cyprus' exemption from International Traffic in Arms Regulations restrictions for fiscal year 2027, preserving access to US defense exports and services.
The Republic of Cyprus Foreign Ministry linked the decision to Foreign Military Sales, Excess Defense Articles access and the bilateral defense cooperation roadmap signed in 2024.
Turkish Cypriot authorities opposed the extension, saying further arms transfers would deepen the military imbalance on the island. Türkiye has also objected to the policy.
Separately, Turkish Cypriot leader Tufan Erhürman and Greek Cypriot leader Nikos Christodoulides meet in the United Nations buffer zone on September 17. Their negotiators, Menelaos Menelaou and Mehmet Dânâ, are preparing the session, but the sides still have no agreed route into a new round of formal negotiations.
Greece and the Aegean
One Dead, Around 25 Missing South of Gavdos
One person died and around 25 were missing Monday after a migrant boat sank about 38 nautical miles south of Gavdos.
Fifty-one people were rescued. Survivors said 77 had been aboard, leaving about 25 unaccounted for as the Hellenic Coast Guard continued operations with passing ships, Frontex assets and aircraft.
Those rescued were being taken to Crete. Gavdos, about 320 kilometers from the Libyan coast, sits on a North Africa-to-southern Greece migration route that has seen heavier traffic in recent months.
Mosque in Xanthi Targeted With Insulting Graffiti
Graffiti insulting religious beliefs was found on the outer wall near the entrance of the historic Çınar Mosque in Xanthi.
The Western Thrace Turkish Minority Advisory Board condemned the vandalism and called for those responsible to be identified. No Greek police or government statement on the incident had been identified by publication time.
Greek Prime Minister Kyriakos Mitsotakis, meanwhile, completed a visit to the Kastellorizo island group on Sunday, with Türkiye and Aegean security again prominent in domestic coverage. Government figures have increasingly linked political stability to national security, while Athens and Ankara continue to trade legal objections over marine parks in the Aegean.
Maritime Security
Silivri Search Continues for 10 Missing Crew
Turkish naval and civilian teams continue looking for the 10 crew members of the Tuğberk İmamoğlu, which sank after colliding with the Turkish-flagged tanker Alsu south of Silivri on September 2.
TCG Akın located the wreck at a depth of about 720 meters and later obtained underwater images with a remotely operated vehicle.
A preliminary expert report submitted during the Silivri prosecutor's investigation identified serious failures in bridge management aboard Alsu. Judicial proceedings against members of its crew continue.
Türkiye's Defense Ministry says naval units are working around the clock off both Silivri and Kyrenia.
Türkiye and Syria
Ankara Broadens Damascus Contacts
Foreign Minister Hakan Fidan was on the second day of a two-day visit to Syria Monday after meeting Syrian President Ahmed al-Sharaa and Foreign Minister Asaad Hassan al-Shaibani.
Fidan and al-Shaibani discussed activating the Joint High Committee as a permanent mechanism between the two governments. President Recep Tayyip Erdoğan's planned visit to Syria is also being prepared.
Security remains the difficult file. Fidan said the Syrian Democratic Forces' decision on dissolution and integration now had to be implemented on the ground, continuing the dispute raised during the Damascus visit.
Contacts have also moved into social policy. Family and Social Services Minister Mahinur Özdemir Göktaş said Syrian authorities had begun using Türkiye's foster-family model for abandoned infants and were discussing cooperation on women, children, families and disability policy.
Türkiye Defense
SUNGUR Fires From BURÇ Mobile Air Defense System
Roketsan's SUNGUR air-defense missile destroyed a moving aerial target in its first firing from the BURÇ mobile air-defense system.
BURÇ combines SUNGUR missiles, a 20/30 mm gun and active and passive sensors on a mobile short-range air-defense platform.
The test followed Türkiye's latest long-range strike trial, in which Bayraktar AKINCI hit a maritime target from more than 250 kilometers with Roketsan's UAV-300 supersonic missile.
Hormuz and Energy
Gulf Talks Delayed as Hormuz Traffic Falls and Saudi Bypass Closes
Oman postponed a meeting scheduled for Monday between Iran and Gulf states on shipping through the Strait of Hormuz, saying more time was needed to reach consensus.
Preliminary tracking data showed commodity vessel transits falling to single digits per day over the weekend, below a recent 10-day average of 14. Iran says it will not reopen the strait until the United States meets Tehran's demands.
Saudi Arabia's East-West crude pipeline, its main route around Hormuz, remains shut after an attack. Saudi buyers said stocks at the Red Sea port of Yanbu could sustain current export levels for five to seven days if the outage persists.
Brent traded above $107 a barrel Monday.
The International Maritime Organization says at least 70 attacks on international shipping have been verified since the Middle East conflict began on February 28, killing 19 seafarers. Up to 400 ships carrying around 6,000 crew members have at some point been unable to leave the Persian Gulf safely.
The disruption gives greater weight to alternative Iraqi export routes. Baghdad last week completed the draft of its general agreement with Ankara on the Development Road, where Ceyhan has gained importance in discussions over future Iraqi oil flows.
Black Sea
Shipping Pressure Builds Near Türkiye
Repeated attacks on commercial vessels in the Black Sea are pushing more ships to wait near Turkish anchorages and in the Marmara Sea, while damaged or abandoned vessels drifting toward Türkiye's coast have added a separate navigation hazard.
Turkish maritime authorities have warned crews about vessels left adrift after attacks. Industry representatives say the security situation is also slowing commercial traffic through the Turkish Straits and increasing waiting times around Turkish waters.
The larger industry estimates for the number of ships hit remain difficult to verify independently, but the pattern is clear enough to affect route planning, insurance and crew safety across the Black Sea trade network.
Balkans
Hauliers Threaten Blockade on Türkiye-Europe Freight Corridor
Transport associations in Serbia, Bosnia and Herzegovina, Montenegro and North Macedonia set Monday as the deadline for movement on rules limiting professional drivers to 90 days inside the Schengen area in any 180-day period.
The groups said they would block freight terminals at land crossings with European Union and Schengen states if no workable solution emerged. Bulgaria's Foreign Ministry warned travelers and hauliers to prepare for disruption and consider alternative routes.
The dispute directly affects road freight between Türkiye and European markets through the Western Balkans. Hauliers argue that professional drivers cannot sustain international operations under stay limits designed for ordinary short-term visitors, while enforcement has tightened with expansion of the European Union's Entry-Exit System.
A previous regional blockade disrupted freight for several days earlier this year. Monday's announced action had not been independently confirmed as under way by publication time.
Bosphorus Read
The three maritime operations reached Monday at different stages. Off Kyrenia, crews are preparing to enter a wreck more than 500 meters below the surface. South of Silivri, the wreck has been located and investigators have turned to responsibility. Off Gavdos, rescuers are still relying on survivor accounts to establish how many people remain missing.
Washington's defense decision arrives ahead of Thursday's Cyprus leaders meeting, but the two tracks are separate. The Republic of Cyprus has an established timetable for its security cooperation with the United States. Erhürman and Christodoulides still have to settle how another political process on the island would begin.
Türkiye's relationship with Damascus is acquiring permanent machinery. The Joint High Committee, Erdoğan's planned visit and new cooperation in trade and social policy give bilateral contacts a structure they lacked earlier in Syria's transition. The SDF question is moving more slowly, with Ankara still demanding implementation of a decision already announced.
Türkiye also faces pressure at opposite ends of its trade network. Around Hormuz, war and damaged energy infrastructure are constraining shipping. On the road to European markets, Balkan hauliers are threatening border closures over Schengen stay limits. Neither disruption starts in Türkiye, but both can slow the routes Turkish exporters depend on.
