NATO forces intercepted a missile traveling through Syrian and Iraqi airspace and heading toward Turkey on Wednesday, shooting it down before it entered Turkish airspace. Debris landed in southern Turkey.

This marks the first time a key member of NATO has been targeted. Turkey, however, believes that the strike was intended for a military facility in Cyprus and not for Turkey. Nevertheless, Ankara views this as a major escalation and registered a complaint with Iran’s foreign minister, Abbas Araghchi.

Turkish Foreign Minister Hakan Fidan warned Araghchi that Iran must take care not to expand the conflict in the region.

In an effort to intimidate countries in the region that are both friendly and hostile to Iran, Tehran has ordered strikes against Saudi Arabia, Bahrain, Qatar, Kuwait and the United Arab Emirates. However, this is the first time Tehran has targeted Turkey, which shares a border with Iran.

“We believe the target was a military facility in Cyprus, but the missile veered off course,” a Turkish official said.

Turkey’s Defense Ministry said that fragments of the intercepted missile landed near the town of Dörtyol in Hatay province, and no injuries were reported.

“We warn all parties to refrain from actions that would lead to further escalation of conflict in the region,” the ministry said in a statement. “In this context, we will continue to consult with NATO and our other allies. All necessary steps to defend our territory and airspace will be taken resolutely and without hesitation. We remind all parties that we reserve the right to respond to any hostile actions against our country.”

The ministry did not say if Turkey had invoked Article 5 of NATO, which says that an attack on one is considered an attack on all — so any member of the alliance that is attacked has the right to invoke this article and receive aid even in the form of ground troops. But U.S. Secretary of Defense Peter Hegseth told reporters that he did not think this incident would trigger the collective response of Article 5.

In a statement, NATO said that “The North Atlantic Alliance condemns Iran’s launch toward Turkey. NATO stands in solidarity with all allies, including Turkey, as Iran continues its indiscriminate attacks across the region.”

“Our deterrence and defense posture remains strong across all domains, including air and missile defense,” the statement added.
