North Korea confirmed Thursday that it launched an intercontinental ballistic missile, marking Pyongyang's 12th missile test this year, according to Anadolu Agency.

In a statement, the Ministry of National Defense said the country's Missile Administration conducted a critical test, as reported by the state-run Korean Central News Agency (KCNA).

"The test-fire, conducted under the order given by the head of state of the DPRK (Democratic People's Republic of Korea), updated the recent records of the strategic missile capability of the DPRK and demonstrated the modernity and creditability of its world's most powerful strategic deterrent," KCNA reported, adding that North Korean leader Kim Jong Un personally observed the launch.

Addressing the occasion, Kim described the test as a necessary military action intended to warn rivals, whom he accused of intentionally escalating regional tensions and posing a threat to the DPRK's security.

"As recently witnessed by us, the rivals' dangerous tightening of their nuclear alliance and various adventuristic military maneuvers go to further highlight the importance of strengthening our nuclear forces," the agency quoted Kim as saying.

"We should never allow any threat to approach the security sphere under our state's influence. The security situation of our state and ever-aggravating prospective threats and challenges require us to continue to bolster up our modern strategic attack forces and more perfectly round off our nuclear forces' response posture," he added, affirming, "I affirm that the DPRK will never change its line of bolstering up its nuclear forces."

Earlier, Japan's Defense Ministry said the missile, launched eastward from North Korea’s interior at 7.11 a.m. local time (2211GMT Wednesday), flew for one hour and 26 minutes before landing outside Japan's exclusive economic zone (EEZ), west of Okushiri Island.

The missile was reportedly launched on a lofted trajectory, meaning it was fired at a steep, near-vertical angle, a tactic often used by North Korea to test missiles without overflying neighboring countries.

The missile reached an estimated altitude of over 7,000 kilometers (4,349 miles) and traveled a distance of about 1,000 kilometers (621 miles), identifying it as an "ICBM class," the government said, according to Kyodo News.

There was no damage to planes and ships reported from the missile, it added.
