A satellite launched into space by North Korea on the weekend is in orbit around the Earth, news reports said Tuesday, although it was unclear whether it was functioning properly.
The three-stage rocket that carried the satellite had separated successfully before pushing the device into orbit on Sunday, Yonhap News Agency quoted a South Korean Defence Ministry official as saying.
The launch provoked international criticism and was condemned as a cover for a ballistic missile test.
Senior US defence officials told local media that the satellite appeared to be "tumbling in orbit," and therefore was not functioning properly.
Pyongyang said the mission was a "complete success" and that the Kwangmyongsong-4 satellite went into orbit nearly 10 minutes after the launch.
