Seoul: North Korea claimed November 22 to have successfully placed a spy satellite into orbit with its third launch attempt this year, demonstrating the nation’s determination to build a space-based surveillance system during protracted tensions with the United States.

Though this claim could not immediately be independently confirmed. But the launch was certain to invite strong condemnation from the United States and its partners because the United Nations bans North Korea from conducting satellite launches, calling them covers for tests of missile technology.

The North’s space authorities said in a statement that its space launch vehicle placed the Malligyong-1 satellite into orbit on November 21 night following lift-off from the country’s main launch centre and an intended flight.

The statement said that leader Kim Jong Un observed the launch. It said the fired spy satellite would enhance North Korea’s war readiness in response to its rivals’ hostile military moves and that more would be launched at an early date.

South Korea and Japan said earlier that they detected the North Korean launch. The Japanese government briefly issued a J-Alert missile warning for Okinawa, urging residents to take shelter inside buildings or underground. South Korea’s military said it maintains its readiness in close coordination with the US and Japan.

“Even if North Korea calls it a satellite, the firing that uses ballistic missile technology is a clear violation to related United Nations Security Council resolutions,” Japanese Prime Minister Fumio Kishida said. “It is also a serious threat that affects the safety of the people.”
