An earth observation satellite launched by the Democratic People's Republic of Korea (DPRK) earlier Friday morning has failed to enter orbit, and scientists and technicians are now looking into the cause of the failure, the official KCNA news agency reported.

The Kwangmyongsong-3 satellite was launched at the Sohae Satellite Launching Station in Cholsan County, North Phyongan Province at 07:38 a.m. on Friday (2238 GMT Thursday), said the report.

"The earth observation satellite failed to enter its preset orbit.Scientists, technicians and experts are now looking into the cause of the failure," it said.

The DPRK's failed launch has aroused international concerns, with the United States, Japan and South Korea all condemning the move, which they viewed had breached relevant UN resolutions.

The DPRK has said that its launch is for peaceful purposes and would not harm the region and neighboring countries.
