Why did a drone believed to be Iranian strike Nakhchivan International Airport in Azerbaijan?
Military escalation in the Middle East unexpectedly spread to the South Caucasus in early March 2026. A drone attack attributed to Iran struck the Nakhchivan International Airport in Azerbaijan, raising a major question for the international community: why would a drone attack target the civilian infrastructure of a neighbouring country?
On Thursday, 5 March 2026, at least four unmanned aerial vehicles launched from Iranian territory crossed the border into the Azerbaijani exclave of Nakhchivan. A kamikaze drone of the Arash-2 type reportedly struck the main terminal building of the airport, while the other drones fell near educational facilities in the village of Shakarabad. The incident caused significant damage to infrastructure and wounded at least four civilians.
Iran, for its part, has denied the allegations of attacking Azerbaijan. Tehran also signalled that Israel might be behind the strike. Iran’s official news agency IRNA quoted the Armed Forces General Staff saying that Iran’s forces did not launch any drones into Azerbaijan.
An underlying factor triggering Tehran’s anger is the increasingly close defence partnership between Baku and Tel Aviv. Iran suspects that Azerbaijan provides access to Israeli intelligence (Mossad) to operate a monitoring station along the Iranian border. Tehran views the presence of Israeli assets on its doorstep as a real existential threat.
The attack on Nakhchivan occurred just days after a wave of large-scale air strikes by the United States and Israel on strategic facilities on the Iranian mainland at the end of February 2026. In Iran’s defence doctrine, it tends to carry out asymmetrical retaliatory strikes against countries seen as facilitating or supporting Western and Israeli interests in the region.
Nakhchivan occupies a highly sensitive geographical position. By striking this territory, Iran demonstrates its ability to disrupt logistics routes and damage Azerbaijan’s vital infrastructure without launching a full-scale invasion. This is coercive diplomacy intended to push Azerbaijan away from Western influence.
