Military Posture

Türkiye published Presidential Decision No. 11068 in the Official Gazette on 17 March, imposing a prior clearance requirement on all foreign military cargo transiting Turkish customs territory. The decree covers weapons, ammunition, military explosives, spare parts and related technologies. Shipments now require a letter of conformity from the Trade Ministry, which will consult other state institutions before granting approval. The scope extends beyond formally listed military goods. Items not on the controlled list can be subjected to the same review if authorities suspect military end use, a threat to national or international security, potential contribution to human rights violations or damage to Türkiye's bilateral or multilateral relations. The decree is written as a standing regulatory framework under Türkiye's Customs Law. Its publication during a regional war in which three Iranian ballistic missiles have entered Turkish airspace, 14 Turkish owned ships remain held near the Strait of Hormuz and arms transfer scrutiny across the Middle East is at its highest level in decades makes the timing a policy signal, not a procedural update.

The TRNC declared Nicosia's NOTAM A0345/26 legally void on 16 March, issuing Ercan NOTAM NO100/26. The voided notice had warned of possible military operations over southern and eastern Cypriot waters from surface level to approximately 18,000 feet, covering airspace that overlaps with Ercan Advisory Airspace. The TRNC Ministry of Public Works and Transport stated that the TRNC is the sole authority for air traffic and aeronautical information services in that airspace and urged all aircraft to coordinate exclusively with TRNC units. Nicosia had originally issued NOTAM A0332/26 on 13 March, explicitly naming possible U.S. military operations over a wide area stretching across northern Cyprus and the Mersin, Adana and Hatay coastlines. It later replaced it with A0345/26, stripping the U.S. reference and substituting "possible military operations." A new NOTAM issued on 17 March warned of possible military activity off the Karpas Peninsula in the island's northeast.

Joe Kent, Director of the U.S. National Counterterrorism Center, resigned on 17 March. In a letter posted publicly on X, Kent wrote that he could not "in good conscience" support the war in Iran. He stated that Iran posed no imminent threat to the United States and that the war was started "due to pressure from Israel and its powerful American lobby." Kent is a retired Army Special Forces officer with 11 combat deployments and served under Director of National Intelligence Tulsi Gabbard, who has not commented publicly. Trump responded by calling Kent "very weak on security." Kent's resignation is the highest profile departure from the administration over the conflict.

The multinational military presence around Cyprus remained stable on 17 March. No new deployments were announced. Türkiye's six F-16s and air defence systems at Ercan, deployed on 9 March, remain in place. Greek F-16s and frigates hold position. British, French, German, Spanish, Italian and Dutch naval assets continue operating in or near Cypriot waters. Greece's Achilles Shield air defence programme, approved on 16 March at approximately €3 billion, will begin replacing ageing S-300 and TOR-M1 systems with Israeli supplied Spyder, Barak MX and David's Sling interceptors from late 2026.

Air and Missile Defence

Israel said on 17 March that it killed Ali Larijani, Secretary of Iran's Supreme National Security Council, in an air strike near Tehran overnight. The IDF described Larijani as the "de facto leader of the Iranian regime" since the assassination of Ayatollah Ali Khamenei on 28 February. Israel also said it killed Gholamreza Soleimani, commander of the IRGC's Basij paramilitary militia, and his deputy Seyyed Karishi in a separate strike on a makeshift tent area. An Israeli official told the Jerusalem Post that the majority of the Basij leadership was eliminated overnight. Israel additionally announced it killed the IRGC Aerospace Force chief. Iran has not confirmed any of these claims. Iranian state media published a handwritten note attributed to Larijani commemorating 84 Iranian sailors killed in a U.S. attack, but the note's date was not established.

The IRGC warned on 17 March that U.S. linked industrial facilities across the region could come under imminent attack and called on the United States to evacuate personnel. CENTCOM reported that since 28 February more than 7,000 targets have been struck in Iran, over 6,500 air sorties have been carried out and more than 100 Iranian ships have been destroyed or damaged.

Maritime Security

Trump said on 17 March that the United States does not need NATO allies' assistance to secure the Strait of Hormuz, reversing his position from earlier in the week when he had urged seven countries to send escort vessels. "Because of the fact that we have had such Military Success, we no longer need, or desire, the NATO Countries' assistance. We never did," Trump wrote on social media. He added that Japan, Australia and South Korea were equally unwelcome. The shift followed a cascade of refusals from allied capitals reported in yesterday's brief.

EU foreign ministers on 16 March declined to expand the Aspides naval mandate to cover Hormuz operations. EU foreign policy chief Kaja Kallas acknowledged there was "no appetite" among member states. France's Macron stated on 17 March that France would never participate in operations to unblock the strait while hostilities continue but is preparing a post war freedom of navigation coalition.

Iraq's oil minister said on 17 March that Baghdad is in contact with Iran to negotiate safe passage for Iraqi oil tankers through the strait. A Pakistani flagged Aframax tanker transited Hormuz on 16 March. Iran continues to grant selective passage to ships from countries it considers non hostile, including India, Pakistan and Türkiye, while maintaining its closure to U.S. and allied vessels.

Brent crude traded at approximately $105.70 on 17 March, more than 40 percent above pre war levels. The Suez Canal remains operational but several major container lines have suspended or limited Eastern Mediterranean transits, compounding routing costs and insurance premiums already elevated by the Hormuz closure.

Diplomacy

Canada, France, Germany, Italy and the United Kingdom issued a joint statement on 17 March warning that a significant Israeli ground offensive in Lebanon "must be averted" and could lead to "devastating humanitarian consequences" and a "protracted conflict." The five governments said they support the Lebanese government's efforts to disarm Hezbollah and called for "meaningful engagement by Israeli and Lebanese representatives."

Secretary of State Marco Rubio signed a directive on 16 March, disclosed by Reuters on 17 March, instructing all U.S. diplomatic and consular posts worldwide to urge host governments to designate the IRGC and Hezbollah as terrorist organisations by no later than 20 March. The cable states that advocacy efforts should be coordinated with Israeli counterparts and frames the push as a response to "elevated risk of attack."

Kuwait's Interior Ministry announced on 16 March the arrest of a 16 member cell linked to Hezbollah, comprising 14 Kuwaiti nationals and two Lebanese citizens. Authorities seized firearms, drones, encrypted Morse communication devices, maps and narcotics. Hezbollah denied having any members or networks in Kuwait. Qatar and Bahrain also reported arrests this month of individuals linked to the IRGC. The UAE Foreign Ministry condemned the Kuwaiti cell.

Greek Foreign Minister Gerapetritis and Turkish Foreign Minister Fidan continue what officials describe as a firm but open dialogue aimed at preventing direct escalation between the two NATO allies. Türkiye has criticised Greek militarisation of Aegean islands as a treaty violation. The exchange is running in parallel with Greece's ongoing review of territorial waters expansion and marine park designation in the Aegean.

Cyprus remains in play as a possible venue for eventual Israeli-Lebanese ceasefire talks. Lebanon's President Joseph Aoun is exploring a U.S. mediated political declaration to halt fighting, with diplomatic sources suggesting a permanent non aggression agreement with Israel could be discussed if Hezbollah is sufficiently weakened. Israel has not committed to a negotiating timeline.

Energy and Infrastructure

Yesterday's brief detailed Türkiye's exposure to the Hormuz closure through its Iranian gas dependency, the rising strategic weight of the TANAP/TAP corridor and the Ceyhan terminal's position as one of the few Eastern Mediterranean oil export points outside Gulf shipping risk. Those fundamentals have not changed. What has changed in the past 24 hours is the direct targeting of Gulf energy infrastructure.

A drone struck a fuel tank near Dubai International Airport on 16 March, causing a fire and temporarily suspending flights. Emirates resumed limited service later that day. Iran hit an industrial zone in Fujairah with a drone on 17 March and struck a tanker anchored off the Fujairah coast, one of approximately 20 vessels hit since the war began. A missile impact killed one person in Abu Dhabi, the eighth fatality in the UAE since 28 February. In Sharjah, an Iranian drone struck an industrial area on 17 March. Saudi Arabia intercepted 37 drones over its eastern provinces on 16 March.

Fuel shipments from Iraq intended for Lebanon's power plants will not reach the country because of the Hormuz closure, according to the London based Al Arabi Al Jadeed. Lebanon's energy crisis, already severe before March, is deepening as the war cuts its last remaining supply line from the Gulf.

The ENI/TotalEnergies consortium remains in the final stage of a decision on the Kronos gas field in Cyprus's Block 6, with a target set by President Christodoulides to complete formalities by the Egypt Energy Show on 30 March. ENI's COO said in January that first gas could reach European markets via Egypt's Damietta LNG terminal by late 2027 or early 2028. The Aphrodite field agreement with Israel remains under discussion with no confirmed timeline.

Israel, Lebanon Front

Israel launched what it termed "limited and targeted ground operations" in southern Lebanon on 17 March. The IDF confirmed that the 36th Division and 91st Division are operating in the area to "establish the forward defensive posture." Defence Minister Israel Katz said displaced Lebanese civilians will not return south of the Litani until the safety of northern Israeli residents is guaranteed. Katz stated the operations will resemble the Israeli campaign in Gaza. IDF Chief of Staff Eyal Zamir said the army is determined to "deepen" operations until all objectives are achieved. An IDF spokesman said Israel expects operations against Hezbollah to continue for at least three more weeks.

Israeli public broadcaster KAN reported on 16 March that the military has submitted a request to raise the reservist mobilisation ceiling from the current 260,000 to 450,000, pending approval from government ministers and the Knesset Foreign Affairs and Defence Committee. The proposal has not yet been formally approved.

Hezbollah maintained a sustained offensive tempo. The Alma Research Center documented 37 attack waves against Israel on 16 March, comprising 29 rocket and missile barrages, five drone attacks and three anti tank missile strikes. Since 2 March, 522 attack waves have been recorded. Hezbollah reported direct clashes with Israeli forces in Khiam and multiple border towns. The IDF warned on 17 March that Hezbollah plans major rocket fire at central and northern Israel in coming hours.

Lebanon's Health Ministry reported on 17 March that at least 912 people have been killed since 2 March, including 111 children, with 2,221 wounded. More than one million Lebanese are registered as displaced. The UN human rights office said on 17 March that Israeli attacks on residential buildings and civilian infrastructure in Lebanon may amount to war crimes.

A Lebanese army soldier was killed on 17 March after being wounded in Israeli strikes on Qaqaiyat al Jisr, bringing the total Lebanese military casualties to at least four since the start of fighting.

***Casualty figures from Lebanon and Gaza are drawn from local health authorities and international agencies. Israeli military claims are attributed as stated. Iranian missile and drone statistics are based on Iranian state media. Independent verification of all figures remains incomplete.
