North Korea fired three ballistic missiles early on Wednesday morning, South Korea’s military has said.
Authorities in Seoul said the missiles were fired in the space of less than an hour from the Sunan area in Pyongyang.
It comes just a day after US President Joe Biden left the region, following a trip that saw him vowing to bolster measures to deter North Korea.
North Korea has been test-firing a flurry of ballistic missiles since the beginning of this year.
Japan confirmed at least two launches happened on Wednesday but acknowledged there may have been more.
