Air raid sirens sounded Friday at Incirlik Air Base, a major facility belonging to the North Atlantic Treaty Organization (NATO), according to the official Anadolu Agency.
The base is located near the city of Adana in the southeast of the country, where U.S. forces are stationed.
No official comment has been issued so far regarding the incident, and the reason for the activation of the sirens remains unknown.
Four days ago, NATO air defenses intercepted a ballistic missile in Turkish airspace that had been launched from Iran, the second such incident within five days.
Last Monday, the United States announced the closure of its consulate in the city of Adana and urged all American citizens to leave southeastern Turkiye.
