SEOUL, South Korea (AP) — North Korea called the ongoing South Korean-U.S. military drills a plot to invade the country, as it threatened Tuesday to take unspecified “responsible” military steps in response.

The North’s warning came a day after the South Korean and U.S. forces kicked off their annual computer-simulated command post training and a variety of field exercises for an 11-day run.

North Korea has previously reacted to South Korean-U.S. exercises with launches of a barrage of missiles into the sea.

South Korea’s Joint Chiefs of Staff said last week that this year’s military drills with the United States were designed to neutralize North Korean nuclear threats and would involve live-firing, bombing, air assault and missile interception drills.

This year, North Korea performed six rounds of missile tests and artillery firing drills.

Experts say North Korea could believe a bigger weapons arsenal would provide it with a greater leverage in future diplomacy with the United States.
