The DPRK fired at least three short-range missiles on Saturday morning, according to South Korean and US military.
The missiles, flying more than 250 kilometers in the northeastern direction, were fired from a site in Kittaeryong in the eastern province of Gangwon at around 6:49 a.m. local time, according to South Korean military.
U.S. Pacific Command said the launches of three short-range ballistic missiles were detected, adding that the first and the third missiles failed in flight and the second "appears to have blown up almost immediately."
The U.S. military also said the launches did not pose a threat to Guam or north America.
Sources from Japanese government also confirmed the launches, adding that it did not directly affect to Japan, NHK reported.
The launch came one day after DPRK's Songun Day, a public holiday to celebrate the start of the "military first", or "Songun" policy. It also came a month after Pyongyang test-fired another intercontinental ballistic missile, which is capable of reaching the U.S. state of Alaska.
