North Korea launched a space rocket on Wednesday, presumably carrying its first spy satellite, triggering a civil defense alert on Japan’s Okinawa Island, APA reports citing Yonhap news agency.
The J-Alert system advised Okinawa residents to take shelter in buildings or under ground.
The Defense Ministry of Japan said a ballistic missile launch was carried out.
In turn, the South Korean military said the launch was presumably carried out in order to deliver a spy satellite to the orbit.
Meanwhile, residents of South Korea's capital Seoul were told to prepare for a possible evacuation.
