North Korea fired "unidentified projectiles" on Saturday morning. They ended up in the Japanese Sea, reports South Korean news agency Yonhap based on military information. The projectiles were launched from the eastern province of Hamgyŏng-namdo.
The launch follows a number of previous missile tests conducted by the Pyongyang regime.
North Korea has increased the number of missile trials after talks with the United States about the dismantling of the Pyongyang nuclear program have failed.
On Friday a top diplomat from the isolated country said North Korea is ready for both a dialogue and a confrontation with the United States.
North Korea has been conducting nine rocket tests since May. US President Donald Trump announced earlier this month not to worry about the tests.
