SEOUL, Feb. 7 (Xinhua) -- The Democratic People's Republic of Korea (DPRK) on Sunday launched a long-range rocket as planned, Yonhap news agency reported citing South Korea's defense authorities.
The rocket was fired at about 9:30 a.m. local time (0030 GMT) from the DPRK's Tongchang-ri launch station on its west coast.
The South Korean military detected the rocket just a minute after the launch with its surveillance assets, seeing the rocket succeed in its first-stage separation.
The first stage of the rocket fell on western waters of South Korea. Additional debris landed on waters near the country's southern resort island of Jeju.
The rocket disappeared from radars of the South Korean military at 9:36 a.m., the military said, noting that more verification will be needed to confirm the final success of the rocket launch.
South Korean President Park Geun-hye called an emergency meeting of the National Security Council (NSC) right after the rocket launch to discuss countermeasures.
Seoul's foreign ministry reportedly requested an emergency meeting of UN Security Council, which bans the DPRK from testing any of its ballistic missile technologies.
There has been no damage reported from civil aircrafts and shipping, South Korea's transport ministry was quoted as saying.
South Korea and the United States are jointly assessing whether the DPRK's rocket launch succeeds.
