The U.S. Air Force says two of its bombers flew over the Korean peninsula in a show of force after recent North Korean missile tests.
Pyongyang carried out a test launch of an intercontinental ballistic missile (ICBM) on July 28 that it said was capable of reaching the U.S. mainland with nuclear weapons.
The U.S. B-1B bombers took off from a U.S. air base in Guam, the military said, and were joined by Japanese and South Korean fighter jets in a 10-hour mission, practicing intercept and formation drills.
"North Korea remains the most urgent threat to regional stability," said General Terrence O'Shaughnessy, Pacific Air Forces commander, in a statement.
"If called upon, we are ready to respond with rapid, lethal, and overwhelming force at a time and place of our choosing."
The announcement coincided with tweets from U.S. President Donald Trump, who criticized Beijing for failing to rein in their North Korean allies.
