Eastern Mediterranean Strategic Brief | March 13, 2026

Military Posture

NATO air and missile defence assets intercepted a third Iranian ballistic missile over Turkish airspace on Friday. Sirens sounded at Incirlik Air Base near Adana at 3:25 a.m. before the interception. A U.S. defence official confirmed to the AP that the USS Oscar Austin, an Arleigh Burke-class destroyer based in Rota, fired an SM-3 interceptor. It is the third such interception in two weeks.

The Turkish Ministry of National Defence issued a statement: "A ballistic munition launched from Iran and entering Turkish airspace was neutralized by NATO air and missile defense assets deployed in the Eastern Mediterranean. All necessary measures are being taken decisively and without hesitation against any threat directed at our country's territory and airspace. Consultations are being conducted with the relevant country to clarify all aspects of the incident. All developments in the region are being closely monitored and assessed with national security as the foremost priority."

NATO spokesperson Allison Hart confirmed: "NATO remains vigilant and stands firm in its defence of all Allies."

Previous interceptions occurred on March 4 over Hatay and March 9 over Gaziantep. All three missiles were tracked from Iran through Iraqi and Syrian airspace. A Patriot battery was deployed to Malatya this week to reinforce the Kürecik radar station. Seven U.S. guided-missile destroyers are operating in the Eastern Mediterranean.

France's Charles de Gaulle carrier group was off Crete heading toward Cyprus. Greece's frigates Kimon and Psara are patrolling Cypriot airspace. Spain's Cristobal Colon was docked at Souda Bay.

Türkiye deployed six F-16 fighter jets and air defence systems to Northern Cyprus on March 9. The Ministry of National Defence described the move as part of phased planning to strengthen security for the Turkish Cypriot community and warned that additional measures would be taken if needed. The deployment came four days after Greece sent four F-16s and two frigates to the Republic of Cyprus following the Iranian drone strike on RAF Akrotiri. Cypriot President Nikos Christodoulides said Türkiye's action was a reaction to the message sent by EU member states that Cyprus's security is a shared European responsibility.

Air and Missile Defence

Iran's Embassy in Ankara denied responsibility via its official X account: "No munitions have been launched from Iran toward Türkiye. Taking into account the recent meeting between the President of the Islamic Republic of Iran and the President of the Republic of Türkiye, as well as the contacts between the foreign ministers of the two countries, the Islamic Republic of Iran has announced its readiness to establish a joint technical team to thoroughly investigate this matter in order to resolve any ambiguities. As previously stated, the Islamic Republic of Iran respects the national sovereignty and territorial integrity of the Republic of Türkiye, a friendly and neighboring country."

Maritime Security

Transport Minister Uraloglu confirmed Thursday that one Turkish-owned vessel, the Rozana, passed through the Strait of Hormuz after Iran granted permission. "We had 15 ships there. We obtained permission from the Iranian authorities for one of them because it had used an Iranian port, and we got it through." Fourteen vessels remain waiting with 171 Turkish personnel on board. Türkiye has issued its highest maritime security warning for the strait. Turkish Airlines and AJet have cancelled regional flights until at least March 19; 76 flights have diverted to Turkish airports since February 28.

Diplomacy

Türkiye is mediating between Tehran and Washington alongside Oman, Egypt, and Pakistan. Iran has refused direct talks and is presenting preconditions.

On March 12, Fidan held a joint press conference in Ankara with German FM Wadephul: "We have been experiencing the most intense moments of the war in the last few days. The question is, what chances are there for negotiation, to what extent is it possible? This war should end as soon as possible. We are talking to the Iranian side, and we are talking to the American side. But there is an ongoing military operation, there are certain realities: This unprovoked attack on Iran is as unjust and unlawful as Iran's attacks on Gulf countries."

Fidan also warned against external interference inside Iran: "We are firmly opposed to any plan aimed at sparking a civil war in Iran or fueling conflicts along ethnic or religious fault lines. We are warning those who seek to get involved in such reckless ventures right now: no one should entertain such a fantasy. We will not allow even a single misstep to be taken."

On Lebanon, Fidan said: "Israel's attacks must end before the Lebanese state collapses. The displacement of nearly a million people from their homes is absolutely unacceptable."

Trump told G7 leaders Wednesday that Iran was "about to surrender," according to three officials briefed on the call. A French soldier was killed in a drone attack near Erbil on Friday, the first confirmed French military fatality of the war.

Energy and Infrastructure

Brent crude held above $100 per barrel. Saudi Arabia's East-West pipeline is diverting crude to Yanbu; the UAE is routing exports through Fujairah, but neither replaces Hormuz volumes. Qatar LNG output remains disrupted. The London insurance market's war risk area now includes Oman's ports of Salalah and Sohar.

Cyprus confirmed this week that it is targeting first gas exports by early 2028. Energy Minister Michael Damianos told a parliamentary committee that a final investment decision on the Cronos field, operated by Eni and TotalEnergies in Block 6 of Cyprus's Exclusive Economic Zone, is expected by the end of March. Under the plan, gas will be processed at Egypt's Zohr facilities and liquefied at the Damietta LNG plant for export to European markets. With Brent above $100, investor attention to Eastern Mediterranean supply alternatives has sharpened.

Israel-Lebanon Front

Lebanon's Health Ministry reported 773 killed and 1,933 wounded since March 2, including 103 children. Over 800,000 people are displaced. Israel struck the Zrariyeh bridge over the Litani River on Friday, the first acknowledged strike on civilian infrastructure in the current campaign. It claimed Hezbollah used the bridge but provided no evidence. Netanyahu vowed to continue operations. UNIFIL, the UN peacekeeping force in southern Lebanon, has monitored over 210 Hezbollah missile launches into Israel since March 2.

Intelligence and Security

Greek authorities have arrested five people on espionage and sabotage charges since June 2025, all connected to NATO military assets. Three arrests targeted surveillance of Souda Bay, where the USS Gerald R. Ford docked before the strikes on Iran. A Greek Air Force colonel, Christos Flessas, confessed to passing classified NATO information to China. A Greek port worker was arrested for sabotaging German Navy warships at the Blohm+Voss shipyard in Hamburg.

Greece's National Intelligence Service published its 2025 annual report on Thursday, covering September 2024 to December 2025. The 30-page document identifies the conflicts in Ukraine and Gaza as active threats to Greek national security and describes intensified monitoring at key Greek ports. It also records a 304 percent increase in arrivals via the Libya-Crete migration route and documents cyber threat groups linked to foreign states operating inside Greece.
