Azerbaijan accused Iran on Thursday of firing two drones at its territory, injuring two people, and said it had summoned the Iranian ambassador in order to issue a strong protest.
The Azerbaijani Foreign Ministry said one drone fell on an airport in Nakhchivan, near the border with Iran, and another landed near a school.
In a statement, it condemned the attacks, demanded an explanation from Iran, and said Azerbaijan reserved the right to take "appropriate response measures".
There was no immediate comment from Iran.
