Azerbaijan's foreign ministry lodged an official protest with ​the Iranian embassy on Thursday after a pair ‌of Iranian drones flew across the border into Azerbaijan and injured two people at an airport in the Nakhchivan exclave.
"This attack ​on the territory of Azerbaijan contradicts the norms ​and principles of international law and contributes to increased ⁠tensions in the region," the foreign ministry said ​in a statement.

"We demand that the Islamic Republic of Iran ​clarify the matter in the shortest possible time, provide an explanation and take the necessary urgent measures to prevent such incidents from ​recurring in the future."
