Several U.S. bombers and fighter jet escorts flew in international waters off North Korea's coast on Saturday as a display of "resolve" against the nation's "reckless" behavior, the Pentagon announced.
The mission included several B-1B bombers launched from the U.S. Pacific island territory of Guam, as well as fighter escorts launched from Okinawa, Japan.
The Department of Defense (DOD) said the mission was the furthest north of the Demilitarized Zone (DMZ) that any U.S. military aircraft have flown in more than a dozen years.
"This is the farthest north of the Demilitarized Zone (DMZ) any U.S. fighter or bomber aircraft have flown off North Korea’s coast in the 21st century, underscoring the seriousness with which we take the DPRK’s reckless behavior," DOD spokeswoman Dana White said.
"This mission is a demonstration of U.S. resolve and a clear message that the President has many military options to defeat any threat," she added. "We are prepared to use the full range of military capabilities to defend the U.S. homeland and our allies."
President Trump and North Korean leader Kim Jong Un have been trading insults since Trump's address before the United Nations General Assembly on Tuesday, during which he referred to Kim as "Rocket Man" and threatened the country's destruction if it forced the U.S. to act.
In a response, Kim threatened to "tame" Trump with "fire."
"I will surely and definitely tame the mentally deranged U.S. dotard with fire," Kim said in a rare video statement this week. "A frightened dog barks louder."

North Korea conducted a second test of a hydrogen bomb earlier this month, and last week fired a missile that flew over Japan before landing in the Pacific Ocean. The latter test prompted sirens in Japan and an advisory from the government to seek shelter.
