North Korea may attempt a third spy satellite launch in Japanese territory as early as midnight on Wednesday (today)
Tokyo says Pyongyang has notified them of a nine-day window for the launch, which closes at 23:59 local time (14:59 GMT) on 30 November.
Japan will work with South Korea to “strongly urge” the North not to proceed with the launch, which they said would violate UN resolutions.
Pyongyang has twice failed this year to get a spy satellite into space.
The Japan Coast Guard said Pyongyang’s notification designated three maritime zones believed to be the areas where debris from the rocket carrying the satellite will fall.
Meanwhile, Kang Ho-pil, chief director of operations at the South Korean Joint Chiefs of Staff, warns that Seoul will take “necessary measures” should the launch proceed.
