North Korea accused the United States on Tuesday of pushing the Korean Peninsula to the brink of nuclear war after a pair of strategic U.S. bombers flew training drills with the South Korean and Japanese militaries in another show of strength.

The two supersonic B-1B Lancer bombers were deployed amid rising tensions over North Korea's dogged pursuit of its nuclear and missile programs in defiance of United Nations sanctions and pressure from the United States.

The flight of the two bombers Monday came as U.S. President Donald Trump said he was open to meeting North Korean leader Kim Jong Un in the right circumstances, and as his CIA director landed in South Korea for talks.
