North Korea has revealed photographs of its latest missile launches, including an intercontinental ballistic missile (ICBM) while condemning recent military exercises between South Korea and the United States as an "open provocation and deadly war practice" to which it had to respond.

North Korea will continue to respond to military exercises by South Korea and the United States with "sustained, resolute, and overwhelming practical military measures," the official Korean Central News Agency (KCNA) reported on Monday, citing a statement from the General Staff of the Korean People's Army.

North Korea fired multiple missiles this week, including a probable failed intercontinental ballistic missile, cruise missiles, and hundreds of artillery shells, as South Korea and the United States extended their Vigilant Storm air drills from five to six days in response to Pyongyang's tests.

According to the KCNA article, the North Korean military described the exercises as an "open provocation designed to purposely escalate tensions" and a "dangerous war simulation of a very high aggressive nature."

Hundreds of American and South Korean aircraft, including B-1B bombers, participated in Operation Vigilant Storm.

It was the first time since December 2017 that B-1Bs have flown to the Korean peninsula.

KCNA reported that North Korea's army simulated many strikes on enemy air bases, aircraft, and a key South Korean city to "crush the enemies' incessant war hysteria." It was not specified whether North Korean leader Kim Jong Un supervised the launches.

It confirmed launching two allegedly nuclear-capable "strategic" cruise missiles on November 2 towards the waters of the southeastern South Korean city of Ulsan.

One of the missiles landed 26 kilometers (16 miles) south of the Northern Limit Line, which serves as an unofficial maritime border between the two Koreas. This is the first time this has occurred since the armistice that concluded the Korean War in 1953.

The exercises also included the firing of two "tactical ballistic missiles laden with dispersion warheads," the testing of a "unique functional warhead paralyzing the enemy's operation command system," and a "combat sortie" involving 500 fighter jets.

North Korea typically reacts strongly to joint US-South Korea drills, perceiving them as invasion preparations.

According to experts, Pyongyang is especially sensitive to exercises like Vigilant Storm because its air force, which lacks high-tech jets and well-trained pilots, is one of the weakest components of its military.
