Azerbaijan's ambassador to the US told Axios his country is taking "appropriate defensive and precautionary measures" following an Iranian drone strike on Azerbaijan’s Nakhchivan exclave, Axios reports.

Asked if he was worried about another attack, Ambassador Khazar Ibrahim said it's "not about worrying." Instead: "We are calculating, we are looking at facts, and we are making decisions."

He said Baku and Washington are in close contact over the incident.

The two governments have a long history of cooperation, including providing airspace and air refueling rights during the global war on terror.

Iran must apologize, provide an official explanation, ensure that those responsible for this are held accountable, and guarantee that such things will never happen again, Ibrahim said.

Iran, however, has denied responsibility for the aforesaid salvo.
