Iran’s Arash-2 Drones Hit Azerbaijan Exclave, Dragging South Caucasus Into Wider War

Iranian drones struck Azerbaijan’s Nakhchivan exclave on March 5, hitting the international airport terminal and narrowly missing a school, wounding four civilians and triggering President Ilham Aliyev’s threat of an ‘Iron Fist’ military response that risks pulling Turkey into direct confrontation with Tehran.

The attack marks the first expansion of the six-day-old US-Israel war against Iran into the South Caucasus, shattering Azerbaijan’s attempted neutrality and opening a dangerous new front just kilometers from critical energy infrastructure. Aliyev placed Azerbaijan’s armed forces on “full combat readiness” and demanded Iran apologize and prosecute those responsible for what he called an “act of terror”.

Precision Strike With Strategic Drones

According to Euronews, technical monitoring systems confirmed that four unmanned aerial vehicles belonging to Iran’s armed forces were directed toward Azerbaijan’s Nakhchivan region. One drone struck the terminal building of the airport in the Nakhchivan Autonomous Republic, while another drone fell near a school building in the village of Shakarabad, according to Al Jazeera.

Initial reports suggesting Shahed-series Drones were later corrected. The attack used Arash-2 long-range kamikaze drones with a strike range of roughly 2,000 km and a large warhead reportedly around 150 kg, Aerospace Global News reported. Azerbaijani anti-air defenses shot down one of the drones, according to Eurasianet.

The ‘Iron Fist’ Doctrine

Aliyev’s response was immediate and uncompromising. “They should not test our strength. Those who did so in the past had their skulls crushed with our ‘Iron Fist,'” Aliyev stated, according to OilPrice.com. “Our Armed Forces have been instructed to prepare and implement appropriate retaliatory measures”.

The timing amplified Aliyev’s anger. Hours before the strike, Iran’s deputy foreign minister called Baku requesting Azerbaijan assist in evacuating Iranian embassy staff from Lebanon. Aliyev “immediately instructed that assistance be provided and that an aircraft be sent,” but hours later Iran struck Nakhchivan “in such a treacherous and dishonorable manner. This stain will never be erased from their disgraceful image”, he said during a Security Council meeting broadcast by Euronews.

Iran denied responsibility. “The Islamic Republic of Iran denies its armed forces launched a drone toward the Republic of Azerbaijan,” the Iranian general staff said, though Azer News reported that a Telegram channel affiliated with the Islamic Revolutionary Guard Corps claimed responsibility for the attack in Nakhchivan, according to Wikipedia.

Decentralized Command Creates Escalation Risk

The strike may have resulted from Iran’s wartime doctrine rather than deliberate policy. Military plans reportedly overseen by Khamenei prior to the start of the war called for the devolution of decision-making authority for conducting such drone strikes to field-level commanders in the event of a US and/or Israeli attack, with the strategic logic being to maintain war-fighting ability if senior military command-and-control structures were neutralized, Eurasianet reported.

The decision to launch drones against Nakhchivan could have been made by a relatively junior officer far-removed from those now in charge of the Iranian military. If that is the case, the degree of difficulty for Azerbaijan and Iran in trying to settle relations is much higher than would otherwise be the case.

Nakhchivan: Geography as Vulnerability

The Nakhchivan Autonomous Republic is a landlocked exclave of Azerbaijan covering 5,502.75 km² with a population of 459,600, bordered by Armenia to the east and north, Iran to the southwest, and Turkey to the northwest, according to Wikipedia. The exclave has no direct land connection to mainland Azerbaijan, making the airport a strategic lifeline.

Iran has long opposed the planned transit route, also known as the Zangezur corridor, fearing it would cut the country off from Armenia and the rest of the Caucasus while bringing potentially hostile foreign forces close to its borders, Al Jazeera noted. A land corridor called the “Trump Route for International Peace and Prosperity” gave the US development rights for the proposed route connecting Azerbaijan to its Nakhchivan exclave.

Turkey’s Red Line and NATO Calculus

Turkey’s response was swift and unambiguous. Turkey’s foreign ministry “strongly condemned the drone attacks carried out today on Azerbaijan,” adding that Ankara “will continue to stand by Azerbaijan, as it always has”, Euronews reported.

The statement carries historical weight. During previous conflicts in the area, Turkish Prime Minister Tansu Çiller announced that any Armenian advance on the main territory of Nakhchivan would result in a declaration of war against Armenia. Turkey views Azerbaijan through the prism of ethnic and linguistic kinship — “one nation, two states” — making Nakhchivan’s defense a matter of national interest.

Baku and Washington are in close contact regarding the incident, with the two governments having a track record of cooperation, including overflight and refueling rights during the global war on terror, Azerbaijan’s ambassador to the US told Axios.

The BTC Pipeline Risk Premium

The attack occurred against the backdrop of threats to regional energy infrastructure. Iran signaled it may target the Baku-Tbilisi-Ceyhan (BTC) oil pipeline, with an adviser to the IRGC commander saying Tehran would not allow oil exports benefiting adversaries to continue and warning that Iran could strike the “enemy’s oil supply lines”, Georgia Today reported.

Analysts estimate that Israel receives a significant share of its crude oil through supplies transported via the BTC route and shipped from the Turkish port of Ceyhan to Israeli terminals. The 1,768-kilometer pipeline transports roughly 1 million barrels per day from Azerbaijan’s Caspian fields through Georgia to Turkey’s Mediterranean coast.

The pipeline stretches for more than 1,700 kilometers across three countries and has long been considered strategically sensitive infrastructure. While sections of the route are protected and monitored, its length and geographic exposure make it difficult to fully secure against potential sabotage or missile attacks, security experts told Georgia Today.

Ironically, the attack came on the same day Azerbaijan and Turkey inaugurated the Iğdır-Nakhchivan gas pipeline. The pipeline, operational as of March 5, 2025, ends Nakhchivan’s dependence on Iranian gas, reinforcing Turkey’s role as a reliable energy partner and enhancing Azerbaijan’s energy sovereignty, according to Daily Sabah.

Russia’s Conspicuous Silence

Russia, traditionally a power broker in the South Caucasus, has remained relatively muted. Russia’s official line regarding the US and Israeli strikes on Iran has been to condemn the attacks and position the Kremlin as a guardian of “law” and diplomacy, with authorities calling the crisis an “unprovoked act of armed aggression”, Russia Matters reported.

Yet Moscow issued no statement specifically addressing the Nakhchivan strike. Kremlin spokesman Dmitry Peskov has said Russia has not received a request from Iran to send it weapons during the ongoing war, according to Azer News. The silence may reflect Russia’s delicate balancing act: maintaining ties with Iran while avoiding further estrangement from Azerbaijan, particularly after Aliyev publicly blamed Moscow for the December 2024 Azerbaijan Airlines shootdown.

Armenia’s Calculated Neutrality

Armenia, which surrounds Nakhchivan on two sides, has remained conspicuously quiet. Yerevan reacted to the war in Iran extremely cautiously: the authorities limited themselves to expressing concern and condolences, avoiding direct assessments of the actions of the United States and Israel, the Caucasian Knot reported.

Armenia’s restraint is strategic. Any perceived support for Azerbaijan could damage relations with Iran, its only open border after Turkey and Azerbaijan closed theirs. Yet siding with Iran risks alienating the West at a moment when Yerevan is pivoting away from Russia and toward Europe and the United States.

What to Watch

The next 72 hours will determine whether this becomes a contained diplomatic crisis or the opening of a South Caucasus front in a wider regional war.

Military movements: Watch for Azerbaijani troop deployments near the Iranian border and Turkish military consultations with Baku. Any additional Iranian strikes — accidental or deliberate — could trigger the “Iron Fist” response Aliyev promised.

Energy infrastructure: Oil markets have priced in Middle East risk but not Caucasus disruption. A credible threat to BTC or the South Caucasus Pipeline would send Brent crude toward $90. European gas prices remain sensitive to any supply disruption from Azerbaijan, which now provides critical diversification from Russian supplies.

Regional alignment: Russia’s next move will signal whether Moscow views Iran as dispensable or worth protecting at the cost of Azerbaijani relations. Turkey’s willingness to invoke mutual defense commitments — and NATO’s response — will define the conflict’s outer boundaries.

Diplomatic off-ramps: Responding to Baku’s protest, Iranian Foreign Minister Araghchi said authorities had launched an investigation and wished “a speedy recovery to the injured civilians,” with Azerbaijan’s foreign minister calling on Iran to “take necessary measures to prevent such incidents from recurring in the future”. This represents the narrowest of diplomatic openings.

The decentralized nature of Iran’s wartime command structure — intended as a survival mechanism — may have created an escalation neither Tehran nor Baku wanted. But intent matters less than consequences. With Azerbaijan’s military on full alert, Turkey pledging support, and critical energy infrastructure in the crosshairs, the South Caucasus has become the next test of whether the Iran war can be contained or will continue its geographic creep across Eurasia.
