Pyongyang already carried out two tests of what it said were hypersonic missiles this year
North Korea fired an unidentified projectile, South Korean and Japanese officials said Friday, the nuclear-armed country's third suspected weapons test in just over a week.
"North Korea fires unidentified projectile eastward," Seoul's Joint Chiefs of Staff said, without giving further details.
And Japan's coastguard said it detected "the launch from North Korea of what appears to be a ballistic missile or missiles at 14h55."
A coastguard spokesman said they were still analyzing where it fell and whether it was one object or multiple.
Despite international sanctions over its nuclear weapons program, Pyongyang already carried out two tests of what it said were hypersonic missiles this year, on January 5 and January 11.
After the second test, which was personally supervised by North Korean leader Kim Jong Un, the United States imposed sanctions on five people linked to the country's ballistic weapons program.
