The war in the Middle East has spilled over Iran's northern border, with Azerbaijan saying Iranian drones struck its Nakhchivan exclave on Thursday.
The airport terminal was hit, a drone exploded near a school, injuring civilians, and another drone was shot down.
Azerbaijan's President Ilham Aliyev condemned the incident as an "act of terror", demanded an explanation and apology from Tehran, while placing Baku's armed forces on high alert.
He also touched on Iran's ethnic Azerbaijani population - a sensitive subject for Tehran.
Iran denies any role in Thursday's strikes and has suggested the attack may have been an Israeli false‑flag operation.
