North Korea warned Thursday it would respond with "overwhelming deterrence" against the United States following its deployment of B-1B strategic bombers to the Korean Peninsula earlier this week for a joint air exercise.

SEOUL, South Korea (AP) — The United States flew long-range B-1B bombers in a show of force against North Korea on Tuesday, days after the powerful sister of North Korean leader Kim Jong Un vowed to resist a U.S.-led push to eliminate the North’s nuclear program.

North Korea threatened unspecified retaliation after the U.S. flew long-range bombers over South Korea during training with South Korean warplanes, which North Korea views as practice for an attack against it.
