North Korea continues to flex their military muscles and attempt to intimidate the US and other opponents such as South Korea. In its latest missile test, North Korea has reportedly launched a projectile from a submarine, according to South Korea’s Yonhap news agency.

The launch occurred from a vessel in the Sea of Japan, off North Korea’s eastern coast, officials with South Korea’s Joint Chiefs of Staff told Yonhap. The test comes one day after the United States and South Korea launched joint military exercises on the peninsula. Pyongyang had warned against the drills, threatening to launch a preemptive nuclear strike. CONTINUE
