North Korea said on Sunday that it had fired a Hwasong-15 intercontinental ballistic missile (ICBM) at an angle in a "sudden launch" drill to test the country's strong nuclear deterrent.
It said that the missile was fired from an international airport in Pyongyang in the afternoon.
The missile flew 989 km for 4,015 seconds and reached a height of 5,768.5 km. It landed in international waters in the East Sea.
It was the North's first ICBM launch since November of last year when it fired a Hwasong-17 ICBM.
North cited "military threats" from the U.S. and South Korea that are "getting so serious that they can't be ignored."
The North's latest missile launch, its second missile provocation this year, came after it warned Friday that it would take "unprecedentedly persistent and strong" actions if Seoul and Washington went ahead with their planned combined military exercises.
In a separate statement, Kim Yo-jong, the sister of North Korean leader Kim Jong-un, said that any hostile actions against Pyongyang would be met with a "very powerful and overwhelming" response from the North.
She also said again that the North has "no plans" to meet the South face-to-face.
