North Korea fired two projectiles into the Sea of Japan on Thursday, officials in South Korea and Japan said, in the nuclear-armed country's 20th launch since May.

Japan's Defense Ministry said the North launched two “short-range missiles” that traveled 350-400 km and reached an altitude of about 100 km, adding that they were not believed to have fallen into Japan's exclusive economic zone or territory.

Pyongyang is banned from ballistic missile launches under U.N. Security Council resolutions.
