According to the military statement, the weapons were presumed to be short-range ballistic missiles.
The missiles were launched on Thursday from an area near the eastern port city of Monsanto, the military said. They traveled up to 800 kilometers (497 miles) before splashing down in the sea.
South Korea is in close communication with both the United States and Japan to share information about the launch, it added.
Japan’s defense ministry stated that there was no impact on Japan from the North Korean missiles, according to Japanese public broadcaster NHK.
Is North Korea testing missiles for Russia to fire at Ukraine?
Under United Nations Security Council resolutions, North Korea’s ballistic missile program is prohibited.
However, in recent years, the nuclear-armed nation has made significant progress in developing missiles of all ranges.
The launch may have been conducted to test the performance and stability of missiles intended for export, as stated by the Joint Chiefs of Staff spokesperson for South Korea, Lee Sung-jun, at Thursday’s news briefing.
Experts have long warned that North Korea could be testing weapons for export to Russia to use against Ukraine.
Ukraine and South Korea have both accused North Korea of violating UN sanctions by supplying ballistic missiles to Russia.
A Reuters investigation from February claimed that North Korean-made ballistic missiles used by Russia against Ukraine have displayed a “marked improvement” in accuracy.
