Air and Missile Defence
A ballistic munition launched from Iran entered Turkish airspace on 30 March and was neutralised by NATO air and missile defence assets deployed in the Eastern Mediterranean, the Republic of Türkiye Ministry of National Defence announced. No casualties or damage were reported.
The incident is the fourth of its kind since 4 March. As Bosphorus News reported, previous intercepts were recorded on 4 March in Dörtyol, Hatay; on 9 March over Şahinbey, Gaziantep; and on 13 March near Incirlik Air Base in Adana province. The ministry did not disclose the missile's trajectory, type or intended target. Iran has denied involvement in all three previous incidents. Turkish authorities maintain that technical data points to launches from Iranian territory in each case.
The ministry said "all necessary measures are being taken decisively and without hesitation against any threat directed at our country's territory and airspace."
NATO has deployed two additional Patriot batteries in Türkiye since the war began on 28 February, the most recent announced on 18 March. US Defense Secretary Pete Hegseth has said there is "no sense" the intercepts would trigger Article 5, NATO's collective defence clause.

On 30 March, Türkiye's Centre for Combating Disinformation rejected social media claims that Ankara could join the war on Iran's side or send forces into Lebanon, describing both as disinformation. The government has consistently said it is not a party to the conflict and is focused on de-escalation.
Trump Ultimatum and Diplomacy
President Donald Trump issued his sharpest ultimatum yet on 30 March, posting on Truth Social that the United States would destroy Iran's electric generating plants, oil wells, Kharg Island and possibly all desalination plants if a deal is not reached shortly and the Strait of Hormuz is not immediately reopened. Kharg Island handles approximately 90 percent of Iran's crude exports. US forces have deliberately avoided striking its oil infrastructure until now.
Trump also told the Financial Times that his "preference would be to take the oil in Iran" and that seizing Kharg Island remained an option. "Maybe we take Kharg Island, maybe we don't. We have a lot of options," he said. The Wall Street Journal reported separately that Trump is weighing a military operation to extract nearly 1,000 pounds of highly enriched uranium from Iranian territory. No order has been issued.
Iran's Foreign Ministry described the US 15-point ceasefire plan as "excessive and unreasonable" on 30 March. Tehran has denied that any direct or indirect negotiations are taking place, despite Trump's repeated claims of productive discussions. Iranian Foreign Minister Abbas Araghchi said messages have been exchanged through mediators but stressed this "does not mean negotiations."
Türkiye has been passing messages between Washington and Tehran, Reuters reported. Harun Armagan, vice chairman for foreign affairs in the ruling AK Party, confirmed Ankara has been "playing a role passing messages" between the two sides. Türkiye's position remains unchanged: it is not a party to the conflict and is pressing for a ceasefire.
Military Posture
USS Tripoli, carrying 3,500 sailors and Marines, arrived in the Middle East on 30 March, US Central Command confirmed. The vessel joins a force of approximately 50,000 US military personnel already in the region.
Israel said on 30 March it would widen its ground campaign in southern Lebanon. Prime Minister Benjamin Netanyahu ordered the further expansion of Israel's security buffer zone, with the stated aim of pushing Hezbollah's anti-tank missile range away from the Israeli border. The IDF's 146th Division continued advancing into the western sector of southern Lebanon.
The Houthi movement, a Yemen-based Iran-backed militia, fired two missiles at Israel over the weekend. The group had previously disrupted Red Sea shipping lanes in response to Israel's war in Gaza.
Eastern Border and Kurdish Risk
Iran has begun restricting its own citizens from crossing into Türkiye, Interior Minister Mustafa Çiftçi said, with Iranian nationals entering Türkiye falling by 25 to 30 percent from early-war levels. The number of Iranians returning home from Türkiye has increased. Tehran has not publicly explained the restriction.
Çiftçi visited the Gürbulak border gate in Ağrı on 25 March and confirmed all contingency measures were in place. "I can clearly state that all planning and precautions have been taken here. There is no problem at the moment," he said. Tent camps and buffer zones have been prepared but not activated. Türkiye currently hosts more than 74,000 Iranians with residence permits and approximately 5,000 registered refugees.

Pentagon contingency planning for ground operations inside Iran has raised a direct concern in Ankara. As Bosphorus News reported, any operation that weakens Iranian state control in the country's west would create new room for PJAK, the Iranian branch of the Kurdistan Workers' Party, which operates along Türkiye's eastern frontier. After US-Israeli strikes began on 28 February, the CIA consulted Iranian Kurdish groups including PJAK-linked factions about possible operations against Iranian security forces, CNN and Reuters reported. Türkiye's Defence Ministry said on 4 March it was "closely following" PJAK movements and warned that ethnic separatist activity "negatively affects the overall peace and stability of the region."
The risk intersects with Ankara's domestic political calendar. PKK leader Abdullah Öcalan called on the organisation to disarm and dissolve in February 2025. PJAK rejected that appeal. A prolonged weakening of Iran's western border zone could allow PJAK to absorb PKK fighters opposed to the peace process, placing a spoiler on Türkiye's frontier at a moment when Ankara is trying to protect a rare political opening.

NATO Cohesion
Spain closed its airspace to all US military aircraft involved in the Iran war on 30 March, Defence Minister Margarita Robles confirmed. The move extends a previous ban on the use of jointly operated bases at Rota and Morón and now applies to all US flights linked to the conflict transiting Spanish territory. Emergency flights remain permitted.
"Neither the bases are authorised, nor, of course, is the use of Spanish airspace authorised for any actions related to the war in Iran," Robles told reporters. Economy Minister Carlos Cuerpo described the closure as consistent with Spain's position that the war was "initiated unilaterally and in violation of international law."
The decision forces US military aircraft to reroute around Spanish territory, increasing flight times and logistical complexity. It is the most direct operational refusal by a NATO member state since the conflict began. Trump previously threatened trade consequences after Spain denied access to its bases.
Energy and Maritime
Brent crude hit 116 dollars per barrel on 30 March, up more than 50 percent since 28 February. Trump said Iran would allow 20 oil tankers to transit the Strait of Hormuz on 30 March. Iran did not confirm the claim.
The Strait of Hormuz remains effectively closed to most international traffic. Oil industry executives and analysts have warned that the corridor must reopen by mid-April or the daily supply loss, currently estimated at 4.5 to 5 million barrels, will double. US government officials and Wall Street analysts are beginning to factor in the possibility of prices reaching 200 dollars per barrel if the closure extends further, Bloomberg reported.
Fuel prices in Türkiye are 30 percent higher than at the start of the war, compounding inflation already running above 30 percent annually. Türkiye imports approximately 13 percent of its natural gas from Iran, adding a direct supply vulnerability to the economic pressure the conflict is generating.
Israel-Lebanon Front
Israel continued strikes across southern Lebanon on 30 March, with smoke visible over Beirut's southern suburbs. Lebanese health authorities have reported more than 1,238 people killed since 2 March, including at least 124 children. Approximately one million people, roughly one fifth of Lebanon's population, have been displaced.
Iran's ambassador to Lebanon, Mohammad Reza Sheibani, refused to leave the country on 30 March despite being declared persona non grata and ordered to depart by the Lebanese government. "The ambassador will not leave Lebanon, in accordance with the wishes of the speaker of parliament Nabih Berri and of Hezbollah," an Iranian diplomatic source told AFP.
Iran has made Lebanon's inclusion in any ceasefire deal a condition for ending the war. Israel has given no indication it will halt operations there.
***Transparency note: Trump's claim that Iran agreed to allow 20 tanker transits on 30 March has not been confirmed by Iranian authorities or independent maritime sources. The reported Erdoğan-Trump phone call warning against Kurdish proxy use is sourced to Turkish newspaper Türkiye and has not been confirmed by official Turkish or US statements. Pentagon ground operation planning details are drawn from Washington Post and Wall Street Journal reporting citing unnamed sources and have not been officially confirmed.
