For the second time in three days, the Japanese military and South Korean media said that North Korea today launched a projectile from a submarine towards the Sea of Japan, whose nature was unknown, but it is likely that it was a short-range ballistic missile.

While the Japanese Coast Guard called on its ships to be alert and vigilant of any possible developments, the South Korean intelligence chief expected that Pyongyang would conduct a nuclear test before US President Joe Biden’s upcoming visit to Seoul on the twenty-first of May and to Japan on the twenty-second of it.
