South Korean military has seen a rocket launched by the Democratic People's Republic of Korea (DPRK) successfully flying into orbit, Yonhap news agency reported citing a military official.
The military estimated that the DPRK rocket had entered into orbit, indicating a high possibility for a successful launch.
The official was quoted saying that additional analysis will be needed to determine whether the launched vehicle operates normally.
A South Korean defense ministry official told Xinhua that the success of the launch hasn't been determined yet. He said the final determination will be announced later in the day.
Pyongyang launched a rocket at about 9:30 a.m. (0030 GMT) on Sunday, just a day after the revised notification of its plan to move up the launch window to Feb. 7-14 from the previous Feb. 8-25.
The launch came about a month after what it claimed was its first H-bomb test on Jan. 6 in violation of UN Security Council resolutions.
