The North American Aerospace Defense Command (NORAD) has announced that it has detected and tracked four Russian military aircraft operating within the Alaska Air Defense Identification Zone (ADIZ) on Wednesday.
The Russian planes remained in international airspace and did not enter sovereign U.S. or Canadian territory.
An ADIZ marks the boundary beyond sovereign airspace, requiring all aircraft to be readily identified for national security purposes.
NORAD stated that it utilizes a multilayered defense system, including satellites, ground-based and airborne radars, and fighter aircraft, to detect and monitor activity.
The organization emphasized that it remains prepared to take appropriate action in defense of North America.
This is a developing story and will be updated as more information becomes available.
