The North fired a ballistic missile that landed in the sea near Russian Federation on Sunday in a launch that Washington called a message to South Korea, days after its new president took office pledging to engage Pyongyang in dialogue.
North Korea fired yet another ballistic missile on Sunday (its 10th missile launch over six tests this year), days after its neighbor South Korea elected a new president who has called for greater dialogue with Pyongyang.
While it wasn't immediately clear what type of missile was launched over the weekend, the U.S. Pacific Command said that "the flight is not consistent with an intercontinental ballistic missile".
World leaders have expressed concern after North Korea conducted a further ballistic missile launch on Sunday despite heavy United Nations and U.S. sanctions imposed on it for its pursuit of nuclear weapons.
The launch came two days after the North sent a rare letter to Congress condemning a fresh round of USA sanctions against the nation - and two weeks after its last ballistic test-fire, which failed soon after it launched.
Multiple sets of United Nations and U.S. sanctions against North Korea have done little to deter the country in its pursuit of its nuclear and missile ambitions.
Tensions are running high in the Korean peninsula, with Mr Trump warning last month that a "major, major conflict" with Pyongyang was possible.
Tensions are rising between the US and North Korea, despite President Trump calling North Korean leader Kim Jong-un a "smart cookie" in a recent interview with Face The Nation. The missile flew about 435 miles to the sea of Japan.
In Brussels, NATO spokeswoman Oana Lungescu called Pyongyang's move "a new flagrant breach of a series of United Nations Security Council Resolutions", constituting "a threat to global peace and security".
The launch, if it is confirmed to be test-firing of a ballistic missile, is the first in two weeks since the last attempt to fire a missile ended in a failure just minutes into flight. "We must show that dialogue is possible when the North changes its attitude". It also comes as the U.S., Japanese and European militaries gather for war games in the Pacific.
Prime Minister Shinzo Abe told reporters Sunday that the launch is "absolutely unacceptable" and that Japan will respond resolutely. Delegations from the United States, South Korea and North Korea are also there. But Trump has also called him a "smart cookie" and said he would be "honored" to meet the North Korean leader.
But many say the isolated nation has made a great progress in its nuclear and missile capabilities since Kim took power after the death of his father and longtime ruler, Kim Jong-Il, in 2011.
China, North Korea's sole ally, although it objects to the weapons program, called for restraint and for no one to exacerbate tension.
Launch of a ballistic missile of the DPRK is a new flagrant violation of several resolutions of the UN Security Council.
