United States B-1B Lancer bombers and fighter jets flew in international airspace off North Korea's eastern coast in a show of force.

Pentagon spokeswoman Dana White said in a statement that a fleet of B-1B Lancer bombers escorted by F-15C fighter jets flew off the North's east coast on Saturday.

White added that this is the farthest north of the Demilitarized Zone any U.S. fighter or bomber aircraft have flown off North Korea's coast in the 21st century, underscoring the seriousness with which the United States takes Pyongyang’s reckless behavior.

The bombers were from Andersen Air Force Base in Guam and the fighter jets were from Kadena Air Force Base on Okinawa.

The statement said that the flights are a demonstration of U.S. resolve and a clear message that President Donald Trump has many military options to defeat any threat from North Korea.

The spokesperson said that the United States is prepared to use the full range of military capabilities to defend the U.S. homeland and its allies.
