Traffic through the Strait of Hormuz fell to four vessels as Brent crude moved above $90 and LNG carriers accumulated inside the Gulf. In the Black Sea, a deadly strike on a grain ship and attacks on oil tankers widened the campaign against commercial shipping, while Türkiye explored a possible route out of the S-400 dispute blocking its return to the F-35 programme.
Türkiye also condemned Greece's suspension of eight Turkish minority schools in Western Thrace, saying the number still operating had fallen to 76.
Hormuz Traffic Falls to Four Ships as Brent Tops $90
Only four vessels crossed the Strait of Hormuz on Sunday, down from eight a day earlier, as the United States and Iran continued parallel efforts to control maritime traffic through the waterway.
Brent crude rose above $90 a barrel for the first time since June. The price increase reflected the collapse in normal shipping activity, continued attacks on vessels and uncertainty over how long the overlapping American and Iranian restrictions will remain in place.
The United States has resumed its naval blockade of Iranian ports, while Iran continues to threaten or attack vessels it says have violated its navigation rules. The result is no longer a conventional disruption caused by one side attempting to close the strait. Commercial operators are navigating between two competing enforcement systems backed by military force.
The disruption has also spread beyond crude oil. Only one known LNG cargo has left the Gulf during the past week, while loaded and empty gas carriers have accumulated around export facilities and waiting areas.
Continued production in Qatar and the United Arab Emirates is increasing the volume of LNG held aboard vessels or within regional storage systems. A prolonged interruption would therefore affect both oil markets and gas supply chains serving Europe and Asia.
U.S. Central Command said it had ended its weekend wave of strikes against Iran after nine consecutive nights of operations. The announcement referred to the completion of the latest wave, however, and did not indicate that the wider campaign or naval blockade had ended.
Iran has continued attacks against shipping and military targets across the Gulf. Kuwait and Bahrain reported further Iranian operations, while regional governments kept air defences and emergency systems on heightened alert.
Hormuz traffic has now fallen from severe restriction to near-paralysis. The immediate market effect is visible in oil prices, but the accumulation of LNG carriers suggests the disruption is beginning to spread across the Gulf's wider energy export system.
Deadly Grain Ship Strike and Tanker Attacks Widen Black Sea War
Ukraine accused Russia of striking the Golden Leo, a Guinea-Bissau-flagged grain ship with Turkish commercial links, near Odesa.
The vessel was hit by multiple cruise missiles while carrying grain. Crew members were killed and others remained missing, according to Ukrainian accounts, while survivors included Syrian and Indian nationals. A Ukrainian maritime pilot was also reported among the dead.
Initial reports gave conflicting casualty figures. The attack nevertheless marked another escalation in the direct targeting of civilian and foreign-linked vessels operating around Ukrainian ports.
Russia has intensified strikes against Odesa, Chornomorsk, Mykolaiv and other Black Sea transport infrastructure. Ukrainian grain terminals have reduced or suspended operations, vessel bookings have been cancelled and exporters face shrinking capacity through the country's principal maritime corridor.
Ukraine has simultaneously expanded attacks against Russian-linked shipping and energy infrastructure.
Two oil tankers were attacked at the Caspian Pipeline Consortium terminal off Russia's Black Sea coast, forcing the suspension of oil-loading operations. The terminal handles crude from Kazakhstan and is linked to international energy companies as well as Russian export infrastructure.
The attacks show that the campaign is no longer centred only on ports or naval vessels. Russia and Ukraine are increasingly targeting merchant ships, oil tankers, terminals and the cargo flows that sustain each other's wartime economies.
Bosphorus News previously reported that attacks on vessels and port infrastructure had already reduced Ukraine's grain-export capacity and pushed wheat prices higher.
The Golden Leo strike and the suspension of loading at the CPC terminal extend that pattern. Grain moving out of Ukraine and oil moving through Russia's Black Sea network are now exposed to direct military action within the same maritime theatre.
Reported S-400 Transfer Talks Offer Türkiye a New F-35 Route
Türkiye is reportedly considering transferring its Russian-made S-400 air-defence systems to the United Arab Emirates as part of an effort to resolve the dispute that led to its removal from the F-35 programme.
The Wall Street Journal reported that Ankara was seeking Russian approval for a possible transfer to a Gulf state. No agreement has been announced by Türkiye, Russia, the UAE or the United States.
The proposal would require Moscow's consent because the original sale restricts the onward transfer of the systems. Ankara would also seek assurances that removing the S-400s from Türkiye would lead to the lifting of U.S. sanctions and reopen the path towards acquiring F-35 aircraft.
The S-400 purchase prompted Washington to remove Türkiye from the fighter programme in 2019 and later impose sanctions under the Countering America's Adversaries Through Sanctions Act.
A transfer would address the physical presence of the systems in Türkiye but would not automatically resolve the political dispute. Any F-35 sale would still face scrutiny in the U.S. Congress, where concerns over Türkiye's regional policies, defence relationship with Russia and tensions with Israel remain influential.
Ankara has kept that congressional channel open. Bosphorus News previously reported that former defence minister Hulusi Akar met senior members of the U.S. House defence establishment as Türkiye sought to rebuild support for bilateral military cooperation.
The reported UAE option creates a possible mechanism for removing the immediate S-400 obstacle. It does not yet amount to a transfer agreement, sanctions settlement or commitment to restore Türkiye to the F-35 programme.
Lebanon Seeks Trump Pressure on Israel over Withdrawal
Lebanese President Joseph Aoun is preparing to ask U.S. President Donald Trump to press Israel to withdraw from occupied areas of southern Lebanon and support a phased transfer of control to the Lebanese army.
Aoun is expected to present a written proposal at the White House linking an Israeli withdrawal, Lebanese army deployment and progress towards dismantling Hezbollah's armed presence in the south.
The meeting follows U.S.-mediated Israeli-Lebanese talks in Rome on two proposed pilot zones. The discussions established a technical framework but did not produce a confirmed Israeli withdrawal or handover of territory.
Lebanon wants Israeli forces to begin withdrawing before wider negotiations advance. Israel is demanding security guarantees and measures preventing Hezbollah from returning to areas placed under Lebanese army control.
Hezbollah rejects negotiations over its disarmament while Israeli forces remain in Lebanon. That disagreement continues to block agreement on the sequence of withdrawal, army deployment and weapons collection.
Aoun's decision to take the proposal directly to Trump moves the process beyond technical negotiations. It also places the White House in the position of deciding whether to use American leverage against Israel while supporting a Lebanese government seeking to weaken Hezbollah without triggering an internal confrontation.
No withdrawal has yet been confirmed. The immediate test is whether Washington can turn the pilot-zone framework into a limited territorial handover rather than another round of negotiations without implementation.
Strategic Take
The Hormuz and Black Sea crises are placing simultaneous pressure on the two most important maritime trade systems surrounding the Eastern Mediterranean.
Hormuz is constraining crude oil and LNG flows from the Gulf. The Black Sea campaign is disrupting grain exports, Russian-linked oil loading and the operation of foreign commercial vessels. Both conflicts are moving beyond military targets towards the transport networks that support regional and global markets.
Türkiye's reported S-400 transfer discussions add a separate strategic manoeuvre. Ankara is testing whether a Gulf-based solution can remove the principal technical obstacle to renewed F-35 access, although Russian consent and U.S. congressional approval remain unresolved.
Lebanon's appeal to Trump represents the most active diplomatic track in the current regional picture. It may produce a limited Israeli withdrawal, but only if Washington can bridge the disagreement over whether withdrawal or Hezbollah's disarmament must come first.
