Russian bomber jets were intercepted by U.S. Air Force stealth fighters 50 miles southwest of Chariot, Alaska on Thursday, Fox News reports.
The two "Bear bombers" entered Alaska's Air Defense Zone under the cover of darkness, escorted by a pair of Su-35 "Flanker" fighter jets, officials told the network. They tagged by two U.S. Air Force F-22 stealth fighter jets on routine patrol.
The Russian fighter jets were reportedly unarmed and remained in international airspace.
But this incident turns the chilly relationship between the U.S. and Russia even cooler. In April, Russian bombers were identified flying near Alaska for four consecutive days.
The latest sightings come after The New York Times reported that the Kremlin is feeling "slighted" that it doesn't have the starring role as the foreign policy partner it had expected under the Trump administration.
Since the inauguration of President Donald Trump, there have been three phone calls with Russia President Vladimir Putin, though Trump has hosted one-on-ones with British PM Theresa May, German Chancellor Angela Merkel, Canadian PM Justin Trudeau, Egypt's President Abdel Fattah el-Sisi and China President Xi Jinping.
