North Korea fired an unknown projectile, the South said

It is not clear how many projectiles were fired.

This comes just days after North Korea said successfully tested A hypersonic missile on Tuesday, the third alleged test of such a weapon by the Kim Jong Un regime.

“A possible ballistic missile fired from North Korea. We will notify you as soon as a follow-up report is available,” Japan’s government tweeted on Friday.

This is a developing story, with more to come.
