"As we agreed at the recent G7, the issue of North Korea is a top priority for the global community", Japan's Prime Minister Shinzo Abe said in brief comment on the launch. "We continue to monitor North Korea's actions closely".
The Government mouthpiece, the KCNA, did not reveal details of the launch but said it was organised by the Academy of National Defence Science - an agency believed to be developing nuclear weapons. South Korea approved Friday, May 26, 2017, a civic group to contact North Korea over aid programs, the first such approval since North Korea's nuclear test in January 2016.
Schiff and Wilson, both members of the House Intelligence Committee, said North Korea has detained at least 17 Americans in the last decade, with four still imprisoned.
U.S. President Donald Trump had been briefed on the launch.
The North already has the ability to strike USA allies in the region, such as South Korea and Japan.
Earlier on Sunday, North Korean state media said Kim oversaw a test of a new anti-aircraft weapon system.
The missile was tracked for six minutes, US Pacific Command said, confirming that the projectile landed in the Sea of Japan.
Chinese State Councilor Yang Jiechi is scheduled to arrive in Tokyo on Monday for talks with Shotaro Yachi, the head of the National Security Council, Japan's foreign ministry said in a statement. "We don't have to wait until they have an intercontinental ballistic missile with a nuclear weapon on it to say that now it has manifested completely".
The Security Council statement emphasized "the vital importance" of North Korea "immediately showing honest commitment to denuclearization through concrete action". The United States and its allies have been carefully watching North Korea's tests, as well as its military parades, to monitor the progress of country's secretive missile program. But South Korea's Joint Chiefs of Staff said the missile traveled about 280 miles and could have reached the Japanese zone.
Pyongyang has been under mounting worldwide pressure over its missile and military nuclear programs. The Security Council first imposed sanctions on the DPRK in 2006 following five nuclear tests and two long-range rocket tests conducted by the socialist country.
In recent weeks tested its intermediate-range ballistic missile, making some technical advances.
